Description

  The present invention relates to a power supply device including a fuel cell.

  Conventionally, an apparatus has been proposed in which an organic hydride such as a hydrogenated aromatic is dehydrogenated to generate hydrogen, and the hydrogen is supplied to a fuel cell (see Patent Document 1).

Japanese Patent No. 4849775

  When a hydrogenated aromatic is dehydrogenated in a power supply device to generate hydrogen (hydrogen gas) as in Patent Document 1 and is supplied to a fuel cell to generate power, all hydrogen necessary for power generation is preliminarily high-pressure gas. The safety is improved as compared with the case where the power supply device is provided in this state. However, in the apparatus of Patent Document 1, hydrogen generated by dehydrogenation is temporarily stored in a buffer tank and supplied to the fuel cell.

  In order to improve the safety of this type of power supply device, it is desired to improve the device so that it can operate even if the buffer tank containing hydrogen is small or can operate without a buffer tank. This invention is made | formed in view of the above point, and aims at provision of the power supply device which can solve the said subject.

  The power supply device of the present invention made to achieve the above object includes a dehydrogenation unit that dehydrogenates at least part of an organic hydride to generate hydrogen and a liquid aromatic compound, and the dehydrogenation unit generates A fuel cell that generates power using hydrogen, a storage battery that stores the power generated by the fuel cell, a storage amount detection unit that detects a storage amount of the storage battery, and a storage amount that is detected by the storage amount detection unit are preset. When the stored amount of electricity is equal to or greater than the first stored amount of electricity, dehydrogenation in the dehydrogenation unit is stopped, and the stored amount of electricity detected by the stored amount of electricity detection unit is preset to a value equal to or less than the first stored amount of electricity. And a hydrogenation control unit that starts dehydrogenation in the dehydrogenation unit when it is less than the second power storage amount.

  In the power supply device of the present invention configured as described above, when the storage amount of the storage battery that stores the power generated by the fuel cell is equal to or greater than the first storage amount, dehydrogenation in the dehydrogenation unit is stopped, The dehydrogenation is started when the storage amount is less than a second storage amount (≦ first storage amount). For this reason, the dehydrogenation in the dehydrogenation unit is executed only to the extent necessary and sufficient to maintain the storage amount of the storage battery between the second storage amount and the first storage amount. Therefore, in the present invention, it is not necessary to store surplus hydrogen in the apparatus, and the hydrogen storage section in the power supply apparatus can be omitted or downsized.

  In the power supply device of the present invention, the fuel cell may further include a removable cartridge that stores water generated during power generation. In this case, since the storage part that stores the water generated during power generation by the fuel cell is removable as a cartridge, even if the capacity of the storage part (cartridge) is small, it can be dealt with by appropriately removing the cartridge. Therefore, the power supply device can be further miniaturized in combination with the effect of the present invention in which the hydrogen accommodating portion can be omitted or miniaturized as described above. The water stored in the cartridge may be used for other purposes such as drinking water.

  The power supply apparatus of the present invention may further include a water treatment unit that treats water generated during power generation by the fuel cell by vaporization or electrolysis. In this case, since the water generated during power generation by the fuel cell is processed by vaporization or electrolysis, the accommodating portion for accommodating the water can be downsized. Therefore, the power supply device can be further miniaturized in combination with the effect of the present invention in which the hydrogen accommodating portion can be omitted or miniaturized as described above.

In addition, the terminal 1 generally has a configuration other than that shown in FIG. 1, but these configurations are not directly related to the configuration of the terminal 1 as a power supply device. Illustration and description are omitted.

  The hydrogen supply unit 3 is configured to supply hydrogen to the fuel cell 5. The hydrogen supply unit 3 includes a first tank 17, a second tank 19, a dehydrogenation reactor 21 (an example of a dehydrogenation unit), a gas-liquid separator 23, an adsorber 25, a water tank 27, and pumps 29 and 31. , And pipes 33, 35, 37, 39, 43, and 44.

  The first tank 17 is a tank that can store liquid methylcyclohexane (an example of organic hydride; hereinafter referred to as MCH). The second tank 19 is a tank capable of containing a liquid containing toluene or the like sent out from the gas-liquid separator 23 as will be described later.

  The dehydrogenation reactor 21 is a unit that dehydrogenates at least a part of MCH supplied from the first tank 17 to generate gaseous hydrogen and liquid toluene. The dehydrogenation reactor 21 has a structure in which a metal tube is filled with a dehydrogenation catalyst.

  As the dehydrogenation catalyst, those described in Japanese Patent No. 4849775 can be used. As this dehydrogenation catalyst, for example, a porous γ-alumina carrier having specific physical properties, one or more kinds of catalytic metals selected from platinum, palladium, ruthenium, rhodium and iridium, lithium, sodium A catalyst on which one or more alkaline metals selected from Group 1A and Group 2A of the periodic table including potassium, rubidium, cesium, beryllium, magnesium, calcium, strontium, and barium are supported.

  Such a porous γ-alumina carrier having specific physical properties can be obtained, for example, by a production method disclosed in Japanese Patent Publication No. 6-72005. That is, it can be obtained by filtering and washing a slurry of aluminum hydroxide produced by neutralization of an aluminum salt, and dehydrating and drying the obtained alumina hydrogel, followed by firing at 400 to 800 ° C. for about 1 to 6 hours, Preferably, the pH value of the alumina hydrogel is alternately changed between the alumina hydrogel dissolution pH region and the boehmite gel precipitation pH region, and the alumina hydrogel-forming substance is subjected to pH change from at least one of the pH regions to the other pH region. It is preferable to be obtained through a pH swing process of adding alumina to grow alumina hydrogel crystals.

  The dehydrogenation reaction conditions in the dehydrogenation reactor 21 are preferably such that the reaction temperature is 250 ° C. or higher and 350 ° C. or lower, more preferably 290 ° C. or higher and 350 ° C. or lower. The liquid space velocity (LHSV) of the MCH passing through is 1.0 or more and 5.0 or less, preferably 2.0 or more and 4.0 or less.

  The dehydrogenation reactor 21 includes a heater 21A. The temperature of the dehydrogenation reactor 21 can reach the above-mentioned suitable reaction temperature by adjusting the heat generation amount of the heater 21 </ b> A by the controller 9.

  The gas-liquid separator 23 separates a substance (a mixture of a hydrogen-based gas and toluene and an unreacted MCH-based liquid) discharged from the dehydrogenation reactor 21 into a gas and a liquid. The gas-liquid separator 23 is composed of, for example, a coil made of a tube having a sufficient diameter, and is installed so that the axial direction of the coil is vertical. By introducing the substance discharged from the dehydrogenation reactor 21 into the gas-liquid separator 23 and cooling it, it can be separated into gas and liquid. The separated gas is sent to the adsorber 25, and the liquid is sent to the second tank 19.

  The adsorber 25 adsorbs and removes impurities other than hydrogen from the gas separated in the gas-liquid separator 23. As will be described later, the adsorber 25 has a structure in which a metal container is filled with an adsorbent 25A (see FIG. 3A). As the adsorbent 25A, for example, zeolite, silica, silica alumina, activated carbon and the like can be used. The gas (mainly hydrogen) from which impurities are removed by the adsorber 25 is supplied to the fuel cell 5.

  As shown in FIG. 1, the pipe 33 connects the first tank 17 and the dehydrogenation reactor 21, and the pump 29 is installed in the middle of the pipe 33. The MCH in the first tank 17 is supplied to the dehydrogenation reactor 21 by the pipe 33 and the pump 29.

  The pipe 35 connects the dehydrogenation reactor 21 and the gas-liquid separator 23. The pipe 37 connects the gas-liquid separator 23 and the adsorber 25. The pipe 39 connects the adsorber 25 and the fuel cell 5. A pump 31 is provided in the middle of the pipe 39. The pump 31 sends the gas (hydrogen) discharged from the adsorber 25 to the fuel cell 5. The pipe 43 sends the liquid discharged from the gas-liquid separator 23 to the second tank 19.

  The fuel cell 5 performs an electrochemical reaction using hydrogen supplied from the hydrogen supply unit 3 and air (oxygen) to generate a voltage. The fuel cell 5 generates water by the electrochemical reaction. The water is stored in the water tank 27. The water stored in the water tank 27 can be used for various purposes as described later. The pipe 44 sends water generated by the fuel cell 5 to the water tank 27.

  The control unit 9 includes a CPU 45, a ROM 47, and a RAM 49. The control unit 9 can control each unit of the terminal 1 and execute the same processing as that of a normal terminal. The control unit 9, the HDD 13, and the display 15 are driven by electric power generated by the fuel cell 5.

1.2. Configuration of Cartridge 53 and its Mounting Portion As shown in FIGS. 2A and 2B, the first tank 17 and the second tank 19 are provided in the cartridge 53. The cartridge 53 can be attached to and detached from the casing 55 of the terminal 1.

  The cartridge 53 is a hollow container having a substantially rectangular parallelepiped shape, and a closed space inside the cartridge 53 is partitioned into two closed spaces by a partition wall 54. These two closed spaces constitute a first tank 17 and a second tank 19, respectively.

  One end face 53A of the cartridge 53 is provided with an opening 57 for communicating the inside of the first tank 17 and the outside, and an opening 59 for communicating the inside of the second tank 19 and the outside. . Further, in the end face 53 </ b> A, a cylindrical insertion portion 61 is erected outward around the opening 57, and a cylindrical insertion having a larger diameter than the insertion portion 61 is provided around the opening 59. The part 63 is erected outward.

  A shutter 65 for opening and closing the opening 57 is provided in the cartridge 53. The shutter 65 is rotatable about a rotation shaft 65A provided around the opening 57 in the cartridge 53. Therefore, the shutter 65 can be rotated between a position where the shutter 65 rotates inside the cartridge 53 to open the opening 57 as shown in FIG. 2A and a position where the opening 57 is closed as shown in FIG. 2B. It is. However, the shutter 65 is biased toward a position for closing the opening 57 by a spring (not shown), and is in a position for closing the opening 57 unless an external force is applied.

  A shutter 67 that opens and closes the opening 59 is provided in the cartridge 53. The shutter 67 is rotatable around a rotation shaft 67A provided around the opening 59 inside the cartridge 53. Therefore, the shutter 67 can rotate between a position where the shutter 67 rotates inside the cartridge 53 to open the opening 59 as shown in FIG. 2A and a position where the opening 59 closes as shown in FIG. 2B. It is. However, the shutter 67 is biased toward a position for closing the opening 59 by a spring (not shown), and is in a position for closing the opening 59 unless an external force is applied.

  The housing 55 is formed with a recess 69 into which the cartridge 53 can be inserted with the end surface 53A as the head. A bottom surface 71 is provided on the back side of the recess 69, and two openings 73 and 75 are formed in the bottom surface 71. A pipe 33 (see FIG. 1) is connected to the far side of the opening 73, and a pipe 43 (see FIG. 1) is connected to the far side of the opening 75. The opening 75 and the inner diameter of the pipe 43 are configured to be larger than the inner diameter of the opening 73 and the pipe 33 in accordance with the difference in the diameters of the insertion portions 61 and 63.

  A shutter push-out rod 77, which is an L-shaped rod-like member, is attached to the inner wall of the pipe 33, and its tip 77A passes through the opening 73 and protrudes toward the inlet of the recess 69. A shutter push-out rod 79, which is an L-shaped rod-like member, is attached to the inner wall of the pipe 43, and its tip 79A passes through the opening 75 and protrudes toward the inlet of the recess 69.

  In the housing 55, locking portions 81 and 83, which are a pair of rod-like members, are erected around the recess 69. The locking portions 81 and 83 are opposed to each other with the recess 69 interposed therebetween. The locking portion 81 includes a claw portion 81A that protrudes in the direction of the locking portion 83 at the tip. The locking portion 83 includes a claw portion 83A that protrudes in the direction of the locking portion 81 at the tip. The interval between the claw portion 81A and the claw portion 83A is smaller than the width of the cartridge 53 (the length in the vertical direction in FIGS. 2A and 2B). The locking portions 81 and 83 are made of an elastically deformable member (for example, resin), and can be elastically deformed outward (in the direction of arrow H1 in FIG. 2B).

  As shown in FIG. 2B, in a state where the cartridge 53 is removed from the housing 55, the shutters 65 and 67 are closed, so that the MCH accommodated in the first tank 17 does not leak from the opening 57. The liquid containing toluene or the like stored in the second tank 19 does not leak from the opening 59.

  When the cartridge 53 is attached to the housing 55, the cartridge 53 is inserted into the recess 69 with the end surface 53A at the head, and is pushed in until the end surface 53A contacts the bottom surface 71 as shown in FIG. 2A. At this time, the insertion portion 61 is inserted into the opening 73, and the shutter push-out rod 77 pushes the shutter 65 to open the opening 57, so that the inside of the first tank 17 and the pipe 33 communicate with each other. Moreover, since the insertion part 63 is inserted in the opening 75 and the shutter push-out rod 79 pushes the shutter 67 and opens the opening 59, the inside of the second tank 19 and the pipe 43 communicate with each other.

  In the middle of inserting the cartridge 53 into the recess 69, the locking portions 81 and 83 are pushed outward (in the direction of arrow H1 in FIG. 2B) by the cartridge 53. When the cartridge 53 is inserted until the end surface 53A comes into contact with the bottom surface 71, the claw portion 81A and the claw portion 83A reach the front side (left side in FIG. 2A) from the cartridge 53, as shown in FIG. No force in the outward direction from the cartridge 53 is received. Then, the locking portions 81 and 83 are displaced in the inner direction (the direction of the arrow H2 in FIG. 2A), and the claw portion 81A and the claw portion 83A lock the front end surface 53B of the cartridge 53. As a result, it becomes difficult for the cartridge 53 to fall off the housing 55. When removing the cartridge 53, first, the locking portions 81 and 83 are pushed and spread in the direction of the arrow H1 with a finger, and then the cartridge 53 is pulled out of the recess 69. When the cartridge 53 is pulled out from the recess 69, the shutter push-out rods 77 and 79 are separated from the shutters 65 and 67, so that the shutters 65 and 67 are automatically closed.

1.3. Configuration of Cartridge 153 and its Mounting Portion As shown in FIGS. 3A and 3B, the water tank 27 and the adsorber 25 are provided in a cartridge 153 as a metal container (an example of the cartridge in the invention according to claim 2). Yes. The casing 55 of the terminal 1 is formed with a recess 169 into which the cartridge 153 can be inserted with the one end surface 153A of the cartridge 153 as the head. The cartridge 153 can be attached to and detached from the recess 169. Of the configurations related to the cartridge 153 and the recess 169, the same reference numerals used in FIGS. 2A and 2B are used in FIGS. Description is omitted.

  In the housing 55, locking portions 81 and 83 are erected around the recess 169 in the same manner as the recess 69. The interval between the claw portions 81A and 83A provided at the tips of the locking portions 81 and 83 is smaller than the width of the cartridge 153 (the length in the vertical direction in FIGS. 3A and 3B). Therefore, in the middle of inserting the cartridge 153 into the recess 69, the locking portions 81 and 83 are pushed outward (in the direction of the arrow H1 in FIG. 3B) by the cartridge 153. When the cartridge 153 is inserted to a position where the end surface 153A contacts the bottom surface 171 of the recess 169, the claw portion 81A and the claw portion 83A reach the front side (left side in FIG. 2A) of the cartridge 153 as shown in FIG. 3A. . Then, the locking portions 81 and 83 are displaced in the inner direction (the direction of the arrow H2 in FIG. 2A), and the claw portion 81A and the claw portion 83A lock the front end surface 153B of the cartridge 153. As a result, the cartridge 153 is unlikely to fall off the housing 55. When removing the cartridge 153, first, the locking portions 81 and 83 are pushed and spread in the direction of the arrow H1 with a finger, and then the cartridge 153 is pulled out of the recess 69.

  The cartridge 153 is a hollow container having a substantially rectangular parallelepiped shape, and a closed space inside the cartridge 153 is partitioned into two closed spaces by a partition wall 154. These two closed spaces constitute the water tank 27 and the adsorber 25, respectively. The closed space constituting the adsorber 25 is filled with the adsorbent 25A leaving a gap on the end face 153A side and the end face 153B side. Note that the adsorbent 25A may be, for example, one in which the above-described zeolite, silica, silica alumina, activated carbon, or the like is supported inside steel wool, a wire mesh, or the like. The closed space constituting the water tank 27 is filled with the superabsorbent polymer 27A leaving a gap on the end face 153A side. The superabsorbent polymer 27A is a well-known polymer used for sanitary napkins and the like.

  The end surface 153A of the cartridge 153 is provided with an opening 157 that connects the inside of the water tank 27 and the outside, and an opening 159 that connects the inside of the adsorber 25 and the outside. Further, in the end surface 153A, a cylindrical insertion portion 161 is provided to stand outward around the opening 157, and a cylindrical insertion having a larger diameter than the insertion portion 161 is provided around the opening 159. The part 163 is erected outward.

  In addition, the same shutters 65 and 67 as the cartridge 53 are provided in the cartridge 153. That is, the shutters 65 and 67 can be rotated around the rotation shafts 65A and 67A. As shown in FIG. 3A, the positions where the openings 157 and 159 are opened, and the openings 157 and 157 as shown in FIG. It can be rotated between the position where 159 is closed. The shutters 65 and 67 are biased toward a position for closing the openings 157 and 159 by a spring (not shown), and are in a position for closing the openings 157 and 159 unless an external force is applied.

  A bottom surface 171 is provided on the back side of the recess 169, and two openings 173 and 175 are formed on the bottom surface 171. A pipe 144 is connected to the further back side of the opening 173, and a pipe 39 (see FIG. 1) is connected to the further back side of the opening 175. Note that the inner diameter of the opening 175 and the pipe 39 is configured to be larger than the inner diameter of the opening 173 and the pipe 144 in accordance with the difference in the diameters of the insertion portions 161 and 163.

  On the inner wall of the pipe 144, the pipe 44 (see FIG. 1) protrudes as an L-shaped pipe, and the tip 44 </ b> A of the pipe 44 passes through the opening 173 and protrudes toward the inlet of the recess 169. The pipe 144 is further closed on the back side than the protruding portion of the pipe 44. A pipe 37 (see FIG. 1) protrudes from the inner wall of the pipe 39 as an L-shaped pipe, and a tip 37 A of the pipe 39 passes through the opening 175 and protrudes toward the inlet of the recess 169.

  When the cartridge 153 is attached to the housing 55, the cartridge 153 is inserted into the recess 169 with the end surface 153A at the head, and is pushed in until the end surface 153A contacts the bottom surface 171 as shown in FIG. 3A. At this time, the insertion portion 161 is inserted into the opening 173, and the pipe 44 pushes the shutter 65 to open the opening 157, so that the inside of the water tank 27 and the pipe 44 communicate with each other. For this reason, the water produced | generated by the fuel cell 5 is sent to the inside of the water tank 27 via the piping 44, and is absorbed by the super absorbent polymer 27A.

  Thus, the highly water-absorbing polymer 27A can be opened by the pipe 44, and the end surface 44A is not in contact with the highly water-absorbing polymer 27A even if the end surface 153A is in contact with the bottom surface 171. The water tank 27 is filled with a gap left on the 153A side.

  When the cartridge 153 is attached to the housing 55, the insertion portion 163 is inserted into the opening 175, and the pipe 37 pushes the shutter 67 to open the opening 159. Therefore, the inside of the adsorber 25 and the pipe 37 , 39 communicate with each other. The protruding amount of the pipe 37 with respect to the inlet direction of the concave portion 169 is larger than the protruding amount of the pipe 44 with respect to the inlet direction of the concave portion 169. When the cartridge 153 is attached to the housing 55, the tip 37A of the pipe 37 passes through a through hole 25B formed in advance in the center of the adsorbent 25A and reaches the end surface 153B side of the adsorbent 25A. For this reason, the gas sent from the gas-liquid separator 23 to the adsorber 25 through the pipe 37 is sent from the end face 153B side of the adsorber 25 to the pipe 39 through the inside of the adsorbent 25A. The inner diameter of the through hole 25B is designed such that the gap formed between the pipe 37 and the pipe 37 has a width that does not substantially affect the removal of the impurities.

  Thus, the adsorbent 25A can be opened to the end surface 153A side so that the shutter 37 can be opened by the pipe 37 and the end 37A can penetrate the adsorbent 25A when the end surface 153A comes into contact with the bottom surface 171. The adsorber 25 is filled with a gap left on the end face 153B side.

  When the locking portions 81 and 83 are pushed and spread in the direction of the arrow H1 with a finger, and the cartridge 153 is pulled out from the recess 69, the pipes 37 and 44 are separated from the shutters 65 and 67. Therefore, the shutters 65 and 67 are automatically close up.

2. Processing Performed by Terminal 1 FIG. 4 is a block diagram showing the configuration of the control system of terminal 1. As shown in FIG. 4, the control unit 9 includes the input unit 11, HDD 13, display 15, heater 21 </ b> A, pumps 29 and 31, and a storage amount sensor 8 </ b> A that detects the storage amount of the storage battery 8 (FIG. 4). 1 reference: an example of a storage amount detection unit).

  When the terminal 1 is used, the cartridge 53 in which the MCH is accommodated in the first tank 17 and the second tank 19 is empty is attached to the terminal 1 in advance. In addition, a cartridge 153 having an empty water tank 27 and having a sufficient adsorption function for the adsorbent 25 </ b> A is also attached to the terminal 1.

  When the main power supply of the terminal 1 is ON, in the control unit 9, the CPU 45 reads the program stored in the ROM 47 so that the processing shown in the flowchart of FIG. 5 is repeatedly executed.

  In this process, first, in S1 (S represents a step: the same applies hereinafter), the storage amount CH of the storage battery 8 is acquired via the storage amount sensor 8A. In subsequent S2, it is determined whether or not the charged amount CH acquired in S1 is greater than or equal to a preset upper limit value. If the charged amount CH is less than the upper limit value (S2: N), it is determined in S3 whether the charged amount CH is equal to or less than a preset lower limit value. If the charged amount CH is larger than the lower limit (S3: N), the process is temporarily terminated as it is, and if the charged amount CH is less than or equal to the lower limit (S3: Y), the process proceeds to S4.

  In S4, the energization of the heater 21A and the pump 29 is started to start the dehydrogenation reaction (dehydrogenation) as follows, and the energization of the pump 31 is started to start the fuel cell 5 Once started, the process ends once. Note that if the energization of the heater 21A and the pumps 29 and 31 has already been started when the process proceeds to S4, the energization is continued in S4.

  In response to the process of S4, the following reaction is started inside the terminal 1. As shown in FIG. 1, the pump 29 supplies the MCH in the first tank 17 to the dehydrogenation reactor 21 via a pipe 33. In the dehydrogenation reactor 21, heat is supplied from the heater 21A to cause MCH dehydrogenation reaction to generate gaseous hydrogen and liquid toluene. Some MCH remains unreacted. Those substances are sent to the gas-liquid separator 23 via the pipe 35.

  The speed of the dehydrogenation reaction in the dehydrogenation reactor 21 depends on the amount of heat supplied from the heater 21A. The control unit 9 controls the dehydrogenation reaction speed to an appropriate value by adjusting the amount of current supplied to the heater 21A by a process different from the process shown in FIG.

  In the gas-liquid separator 23, the substance sent from the dehydrogenation reactor 21 is separated into a gas and a liquid. The separated gas is sent to the adsorber 25 through the pipe 37. Further, the separated liquid is sent to the second tank 19 through the pipe 43.

  In the adsorber 25, impurities other than hydrogen contained in the gas sent from the gas-liquid separator 23 are adsorbed by the adsorbent 25A. Thereafter, the gas (mainly hydrogen) is supplied to the fuel cell 5 by the pump 31 and the pipe 39. The electric power generated by the fuel cell 5 is stored in the storage battery 8. Therefore, when the energization of the pumps 29, 31 and the heater 21A is started by the process of S4, the storage amount CH of the storage battery 8 increases.

  Returning to FIG. 5, when the charged amount CH of the storage battery 8 exceeds the upper limit value due to such a reaction (S2: N), the process proceeds to S5. In S5, the energization to the heater 21A and the pump 29 is stopped, the dehydrogenation reaction is stopped, the energization to the pump 31 is stopped, the fuel cell 5 is stopped, and the process is temporarily ended. If the energization of the heater 21A and the pumps 29 and 31 has already been stopped when the process proceeds to S5, the energization stop is continued in S5. Further, the stop of energization of the pump 31 by S5 is performed so that the hydrogen generated in the dehydrogenation reactor 21 after the energization of the heater 21A and the pump 29 is stopped is sufficiently consumed by the fuel cell 5. The timing may be slightly delayed from the stop of energization of the heater 21A.

3. Effects produced by the terminal 1 (1) In the terminal 1, by performing the process of FIG. 5, the dehydrogenation reaction in the dehydrogenation reactor 21 maintains the storage amount CH of the storage battery 8 between the lower limit value and the upper limit value. It is executed only to the extent necessary and sufficient to do. Therefore, it is not necessary to provide a hydrogen storage part such as a buffer tank in the terminal 1. Therefore, the safety of the terminal 1 is improved, and the terminal 1 can be reduced in size favorably. Therefore, the configuration (hydrogen supply unit 3, fuel cell 5, storage battery 8, and control unit 9) as the power supply device in the terminal 1 is also good for a mobile phone charger or the like that is highly needed for safety improvement and downsizing. Can be applied to. In addition, the configuration of the terminal 1 as a power supply device can be favorably applied to various other devices such as electric vehicles (including hybrid vehicles) and household appliances.

  (2) As shown in FIG. 3, the cross-sectional area of the flow path of the pipe 39 is extremely larger than the cross-sectional area of the flow path of the pipe 37. For this reason, it is assumed that the hydrogen generated in the dehydrogenation reactor 21 after the energization of the pump 29 and the heater 21A is stopped in the process of S5 is not sufficiently consumed by the fuel cell 5, and the internal pressure of the pipe 39 is increased. However, the influence of the internal pressure can be mitigated well.

  (3) The terminal 1 includes a water tank 27 for storing water generated during power generation by the fuel cell 5 inside the removable cartridge 153. For this reason, even if the cartridge 153 is reduced in size, it can be filled with water by removing and replacing the cartridge 153. Therefore, the terminal 1 can be further downsized in combination with the effect that the hydrogen storage portion can be omitted as described above. The water stored in the water tank 27 of the cartridge 153 may be used for other purposes such as drinking water.

  (4) The cartridge 153 is provided with the adsorber 25 together with the water tank 27. The adsorber 25 is also a member that needs to be replaced when the dehydrogenation reaction is performed over a certain amount. Therefore, it is desirable to design in advance so that the timing at which the water absorption force of the superabsorbent polymer 27A decreases and the timing at which the adsorption force of the adsorbent 25A decreases. In that case, by replacing the cartridge 153, the water tank 27 that has reached the replacement time and the adsorber 25 that has reached the replacement time can be replaced simultaneously. Therefore, in that case, the maintenance of the terminal 1 becomes easy.

  The replacement time of the cartridge 153 is calculated based on the operation time of the CPU 45, and when the replacement time is reached, notification may be made via the display 15 or the like. Further, the replacement time of the cartridge 153 may be detected by providing a sensor for weighing the superabsorbent polymer 27A.

  (5) In the cartridges 53 and 153, the insertion parts 63 and 163 are configured to have a larger diameter than the insertion parts 61 and 161, and the inner diameters of the openings 75 and 175 vary depending on the difference in diameter. It is configured to be larger than the inner diameter. For this reason, it is possible to satisfactorily suppress the cartridge 53 or 153 from being connected to the housing 55 upside down from the state shown in FIG. 2 or 3.

4). Modifications (1) If necessary, the terminal 1 may be provided with a buffer tank or the like for storing hydrogen in the pipe 39. Also in this case, the buffer tank and the like can be reduced in size as compared with the case where the processing of FIG. 5 is not performed. Therefore, also in this case, the safety of the terminal 1 is improved, and the terminal 1 can be reduced in size favorably.

  (2) The water tank 27 may be a tank that does not have the superabsorbent polymer 27A and has a hollow inside. When the water stored in the water tank 27 is reused as drinking water or the like, it may be more advantageous.

  (3) The water tank 27 does not have the superabsorbent polymer 27A and may be provided with a filter 27C as shown in FIGS. 6A and 6B. As shown in FIGS. 6A and 6B, the filter 27C is provided near the end surface 153A inside the water tank 27, and a portion closer to the end surface 153B than the filter 27C inside the water tank 27 is a water storage chamber 27D. The water stored in the water storage chamber 27D is discharged from the pipe 44 and then passes through the filter 27C. The filter 27C removes impurities from the water discharged from the pipe 44, so that the water has a water quality suitable for drinking. For this reason, the water accommodated in the water storage chamber 27D can be used satisfactorily as drinking water. As described above, the cartridge 153 containing water suitable for drinking may be collected as charitable activities as if the cap of the PET bottle is currently collected, and sent to an area where water is low.

  When the filter 27C is provided in this way, the length of each part is designed so that the tip 44A of the pipe 44 contacts the filter 27C when the cartridge 153 is attached to the housing 55 as shown in FIG. 6A. Is desirable.

(4) The water tank 27 and the adsorber 25 may be detachable as separate cartridges. In that case, when the configuration (3) (the configuration of the water tank 27 shown in FIGS. 6A and 6B) is adopted, drinking water can be collected more easily. Further, the water tank 27 and the adsorber 25 may not be formed into a cartridge and may not be attachable / detachable.
<Second Embodiment>
1. Configuration of Terminal 201 The configuration of the terminal 201, which is an embodiment of the power supply apparatus, will be described with reference to FIG. The terminal 201 is configured in the same manner as the terminal 1 in many parts. Therefore, the same reference numerals used in FIG. 1 to FIG. 6 are used in FIG. 7 for the portions configured in the terminal 201 in the same manner as the terminal 1, and detailed description thereof is omitted, and only the differences will be described.

  As shown in FIG. 7, the terminal 201 includes an MCH production unit 240 (an example of a hydrogen addition unit) that produces MCH by reacting toluene with hydrogen in the hydrogen supply unit 3. That is, the MCH production unit 240 produces MCH by hydrogenating toluene by a well-known method. As an example of a method for producing MCH, there is a method in which hydrogen is added to toluene in the presence of a hydrogenation catalyst such as Pt in a known hydrogenation apparatus.

  The terminal 201 includes pipes 244, 245, 246, a pump 248, and a three-way valve 249 in the hydrogen supply unit 3 in association with the MCH production unit 240. The pipe 244 connects the second tank 19 and the MCH production unit 240, and a pump 248 is provided in the middle thereof. When the pump 248 is driven, the liquid in the second tank 19 is sent to the MCH production unit 240 through the pipe 244. On the other hand, when the pump 248 is stopped, the liquid does not flow through the pipe 244.

  The three-way valve 249 is provided between the pump 31 and the fuel cell 5 in the pipe 39. The pipe 245 connects the three-way valve 249 and the MCH manufacturing unit 240. The three-way valve 249 supplies the hydrogen supplied from the pump 31 through the pipe 39 as it is to the fuel cell 5 through the pipe 39 or toward the MCH production unit 240 through the pipe 245. The solenoid valve is controlled to either one of the above. The pipe 246 connects the MCH production unit 240 and the first tank 17.

  Therefore, when the pumps 31 and 248 are energized to drive the pumps 31 and 248 and the hydrogen supply direction by the three-way valve 249 is set to the MCH production unit 240 side, the first tank 17 Can be supplied with MCH. That is, MCH can be produced by the MCH production unit 240 from toluene sent by the pump 248 via the pipe 244 and hydrogen sent by the pump 31 via the three-way valve 249 and the pipe 245. This MCH is supplied to the first tank 17 via the pipe 246. Further, in the terminal 201, a liquid amount sensor 19 </ b> A that detects the amount of liquid in the second tank 19 is provided in the second tank 19.

2. Processing Performed by Terminal 201 FIG. 8 is a block diagram showing the configuration of the control system of terminal 201. As shown in FIG. 8, the input unit 11, HDD 13, display 15, heater 21 </ b> A, pumps 29 and 31, and storage amount sensor 8 </ b> A are connected to the control unit 9 of the terminal 201 as in the case of the terminal 1. 248, the three-way valve 249, and the liquid amount sensor 19A are connected.

  Even when the terminal 201 is used, the cartridge 53 in which the MCH is accommodated in the first tank 17 and the second tank 19 is empty is attached to the terminal 1 in advance. In addition, a cartridge 153 having an empty water tank 27 and having a sufficient adsorption function for the adsorbent 25 </ b> A is also attached to the terminal 201.

  When the main power supply of the terminal 201 is ON, in the control unit 9, the CPU 45 reads the program stored in the ROM 47 so that the processing shown in the flowchart of FIG. 9 is repeatedly executed.

  In this process, first, in S21, the storage amount CH of the storage battery 8 and the liquid amount L in the second tank 19 are acquired via the storage amount sensor 8A and the liquid amount sensor 19A. In subsequent S23, it is determined whether or not the charged amount CH acquired in S21 is equal to or lower than a preset lower limit value. When the charged amount CH is equal to or lower than the lower limit (S23: Y), the process proceeds to S24.

  In S24, the hydrogen supply direction by the three-way valve 249 is set to the fuel cell 5 side. In subsequent S25, the power supply to the pump 248 is stopped, whereby the production of MCH is stopped. If the energization of the pump 248 has already been stopped at the time when the process proceeds to S25, the energization stop is continued in S25. In S26, the dehydrogenation reaction is started by energizing the heater 21A and the pump 29, and the fuel cell 5 is started by energizing the pump 31, as in S4 described above. As a result, the fuel cell 5 starts generating power and the electric power is stored in the storage battery 8 as in the case where the process of S4 described above is executed.

  If the charged amount CH is larger than the lower limit value (S23: N), it is determined in S27 whether or not the charged amount CH is equal to or higher than a preset upper limit value. If the charged amount CH is less than the upper limit value (S27: N), the process is temporarily terminated as it is, and if the charged amount CH is equal to or greater than the upper limit value, the process proceeds to S30.

  In S30, the hydrogen supply direction by the three-way valve 249 is set to the MCH production unit 240 side. Then, the supply of hydrogen to the fuel cell 5 is stopped, and the power generation by the fuel cell 5 is also stopped. Further, since the dehydrogenation reaction is continued at this time, hydrogen is supplied to the MCH production unit 240.

  In subsequent S31, it is determined whether or not the liquid amount L in the second tank 19 is less than the lower limit value. This lower limit value is set in advance as a lower limit value at which a liquid containing toluene from the second tank 19 can be sent to the MCH production unit 240 to produce MCH. If the liquid amount L is equal to or greater than the lower limit (S31: N), the process proceeds to S33. In S33, when the energization of the pump 248 is started, the MCH manufacturing unit 240 starts manufacturing the MCH, and the process is temporarily ended. In addition, when the energization to the pump 248 has already been started when the process proceeds to S33, the energization is continued in S33.

  Moreover, when the liquid amount L is less than a lower limit (S31: Y), a process transfers to S35. In S35, the dehydrogenation reaction is stopped by stopping energization of the heater 21A and the pump 29. In subsequent S37, the energization of the pumps 31 and 248 is stopped to stop the production of MCH, and the process is temporarily ended.

  If the energization of the heater 21A and the pump 29 has already been stopped when the process proceeds to S35, the energization stop is continued in S35. Further, if the energization of the pumps 31 and 248 has already been stopped when the process proceeds to S37, the energization stop is continued in S37. Thereafter, when the charged amount CH of the storage battery 8 becomes equal to or lower than the lower limit value due to power consumption (S23: Y), the processing of S24 to S26 described above is executed, and the second hydrogenation reaction (S26) of the processing causes the second The liquid amount L in the tank 19 also increases.

3. Effects Produced by the Terminal 201 (1) The terminal 201 includes the same configuration as the terminal 1, and the processing in FIG. 9 includes the same processing as the processing in FIG. Therefore, the terminal 201 has the same effect as the terminal 1.

  (2) In addition, in the terminal 201, when the storage amount CH reaches the upper limit (S27: Y), the dehydrogenation reaction is not necessarily stopped immediately, but the hydrogen obtained by the dehydrogenation reaction It may be diverted to manufacture MCH (S33). The MCH thus produced is supplied to the first tank 17 and can be used again for the dehydrogenation reaction. Accordingly, the number of times that the terminal 201 must be replenished with a new MCH may be reduced compared to the number of times that the terminal 1 must be replenished with a new MCH. Therefore, maintenance of the terminal 201 is further facilitated.

  (3) In the terminal 201, when the dehydrogenation reaction is stopped (S35), the hydrogen supply direction is set to the MCH production unit 240 side (S30). For this reason, even when a dehydrogenation reaction is not stopped immediately, the raise of the internal pressure of the piping 39 can be suppressed. The configuration of the terminal 201 as a power supply device (hydrogen supply unit 3, fuel cell 5, storage battery 8, and control unit 9) is similar to the configuration of the power supply device in terminal 1 as well as a mobile phone charger, The present invention can be favorably applied to various other devices such as automobiles (including hybrid vehicles) and household appliances.

4). Modifications (1) For the terminal 201, a modification similar to the modification described for the terminal 1 can be considered. In other words, a buffer tank or the like is provided in the pipe 39, the superabsorbent polymer 27A of the water tank 27 is omitted, a filter 27C is provided in the water tank 27, and the water tank 27 and the adsorber 25 are separate cartridges. It is possible to implement a modified example in which the 27 and the adsorber 25 are not cartridges. And in those modified examples, the same further effect as having demonstrated the modified example of the terminal 1 arises.

  (2) The MCH sent from the MCH manufacturing unit 240 to the first tank 17 may have a lower purity than the MCH initially filled in the first tank 17. However, even in that case, the yield of hydrogen obtained by the dehydrogenation reaction is merely reduced, and the operation of the terminal 1 is not significantly affected.

  However, if the purity of MCH in the first tank 17 decreases, the amount of stored electricity CH increases due to the execution of the process of S26 and a negative determination is made in S23, and then an affirmative determination is made in S27. It may take a long time to complete. Therefore, when the period reaches a predetermined value set in advance, the control unit 9 may execute processing for displaying a message prompting the replacement of the cartridge 53 on the display 15 or the like.

  (3) In addition, by providing the first tank 17 with a sensor for detecting the concentration of MCH, how much hydrogen is attached to the benzene ring, how much double bond exists, etc. The purity of MCH may be detected, and the detection result may be reflected in the control. In that case, power generation by the fuel cell 5 can be performed more stably, and the terminal 201 can be used stably even when the storage capacity of the storage battery 8 is small.

  (4) Further, considering the fact that the purity of MCH in the first tank 17 varies as in (2) above, the first tank 17 and the second tank 19 are not distinguished, and the partition wall An integral tank that is not partitioned by 54 or the like may be used. In that case, the dehydrogenation reaction by the dehydrogenation reactor 21 and the hydrogenation reaction by the MCH production unit 240 are performed on the liquid in which MCH and toluene are mixed.

(5) Similarly to the terminal 1, the terminal 201 can be various terminals such as a stationary terminal such as a desktop personal computer and an in-vehicle car navigation system, and a portable terminal such as a notebook personal computer and a mobile phone. The configuration of the terminal 201 as a power supply device can also be applied to various other devices such as a mobile phone charger, an electric vehicle (including a hybrid vehicle), and a home appliance.
<Cartridge variants and MCH supply facility>
1. Configuration of Cartridge 253 and Outlet 300 Each of the terminals 1 and 201 adopts a configuration in which the first tank 17 and the second tank 19 are housed in the cartridge 53 and are exchanged when the MCH is consumed. On the other hand, the cartridge 53 of the terminals 1 and 201 may be replaced with a cartridge 253 (see FIG. 10) to which MCH is supplied from the indoor outlet 300 via the hose 270 as follows. Since the cartridge 253 is configured in the same manner as the cartridge 53 except for the following points, the reference numerals used in FIG. 2 are also used in FIG. Detailed description is omitted. Hereinafter, differences will be described.

  The cartridge 253 shown in FIG. 10 is different from the cartridge 53 in that the following openings 257 and 259 and insertion portions 261 and 263 are provided on the end surface 53B. That is, the end face 53B is provided with an opening 257 for communicating the inside of the first tank 17 and the outside, and an opening 259 for communicating the inside of the second tank 19 and the outside. Further, in the end face 53B, a cylindrical insertion portion 261 is erected outward around the opening 257, and a cylindrical insertion portion 263 is erected outward around the opening 259. Has been. Note that the outer diameters of the insertion portions 261 and 263 are the same and are smaller than the insertion portions 61 and 63.

  The hose 270 is configured by bundling two hoses 271 and 273, and one end of the hose 271 is externally fitted to the insertion portion 261. One end of the other hose 273 is fitted on the insertion portion 263. The other end of the hose 271 is externally fitted to a cylindrical insertion portion 331 provided in the plug 330, and the other end of the hose 273 is externally fitted to a cylindrical insertion portion 333 provided in the plug 330. . Hereinafter, the configuration of the outlet 300 and the plug 330 will be described.

  Inside the indoor wall W (inside seen from the inside, that is, the outside of the room), a pipe 281 for supplying MCH in the indoor direction and a pipe 283 for collecting a liquid containing toluene and the like from the indoor side are laid. . The outlet 300 includes plugs 301 and 303 connected to the pipes 281 and 283, and a recess 310 formed by excavating the wall W into a rectangular parallelepiped shape. In addition, please refer to FIG. 11 because the configuration of the outlet 300 is schematically shown in a perspective view. In FIG. 11, the insertion parts 301 and 303 are drawn larger for convenience of explanation.

  The pipes 281 and 283 are configured as prismatic pipes having a rectangular cross section as a whole, and are divided into a pipe 281 and a pipe 283 by a partition wall 284 formed along a plane connecting the centers of the long sides of the rectangular cross section. ing. The end portion on the indoor side of the pipe 281 is narrowed down to a small diameter by the throttle portion 285, and is the insertion portion 301 having the same shape as the insertion portion 61. The insertion portion 301 protrudes from a bottom surface 311 provided on the back side of the recess 310. An end portion on the indoor side of the pipe 283 is narrowed to a small diameter by a narrowing portion 287, and is an insertion portion 303 having the same shape as the insertion portion 63. This insertion portion 303 also protrudes from the bottom surface 311.

  The diaphragm unit 285 is provided with a shutter 295 that changes the communication state between the insertion unit 301 and the pipe 281. Similarly to the shutter 65, the shutter 295 is a member that can rotate about the rotation shaft 295A, and is in contact with the inner surface of the throttle portion 285 to block communication between the insertion portion 301 and the pipe 281; The insertion portion 301 and the communication position where the pipe 281 communicates can be rotated. However, the shutter 295 is biased by an unillustrated spring toward the inner surface of the aperture 285, that is, toward the blocking position, and is in the blocking position unless an external force is applied.

  The diaphragm unit 287 is provided with a shutter 297 that changes the communication state between the plug-in unit 303 and the pipe 283. Similarly to the shutter 67, the shutter 297 is a member that can rotate about the rotation shaft 297A, and is in contact with the inner surface of the throttle portion 287 to block the communication between the insertion portion 303 and the pipe 283, and The insertion portion 303 and the communication position where the pipe 283 communicates can be rotated. However, the shutter 297 is urged by an unillustrated spring toward the inner surface of the aperture 287, that is, toward the blocking position, and is in the blocking position unless an external force is applied.

  The opening with respect to the wall W of the recessed part 310 is comprised by the rectangle which has a long side parallel to the direction where the insertion parts 301 and 303 adjoin. A pair of leaf springs 315 and 315 that are rounded in a direction facing each other are fixed to the pair of inner wall surfaces 313 and 313 of the recess 310 corresponding to the short side of the opening via screws 317 and 317. Has been.

  The end surface 335 of the plug 330 opposite to the insertion portions 331 and 333 (that is, the side inserted into the concave portion 310) is configured in a rectangular shape that is similar to the shape of the opening portion of the concave portion 310 and slightly smaller. The plug 330 is provided with a pipe 337 that is fitted in the insertion portion 301 in a liquid-tight manner when the end surface 335 contacts the throttle portions 285 and 287. The tube 337 opens to the end surface 335 and communicates with the internal space of the insertion portion 331 within the plug 330. Further, the plug 330 is provided with a pipe 339 which is fitted in the insertion portion 303 in a liquid-tight manner when the end surface 335 contacts the throttle portions 285 and 287. The tube 339 opens to the end surface 335 and communicates with the internal space of the insertion portion 333 within the plug 330.

  On the outer surface of the plug 330, concave portions 341 and 341 are formed that engage with the leaf springs 315 and 315 when the tubes 337 and 339 are inserted into the concave portion 310 to the positions where they are fitted into the insertion portions 301 and 303. ing. A state in which the tube 337 is externally fitted to the insertion portion 301 by the engagement of the leaf springs 315 and 315 and the recesses 341 and 341, and the tube 339 is externally fitted to the insertion portion 303 Is maintained.

  A shutter push-out bar 347, which is an L-shaped bar member, is attached to the inner wall of the tube 337, and its tip 347A projects outward from the end surface 335. In addition, a shutter push-out rod 349 that is an L-shaped rod-like member is attached to the inner wall of the tube 339, and the tip 349A projects outward from the end surface 335.

  When the plug 330 is disconnected from the outlet 300, no external force is applied to the shutters 295 and 927, and the communication between the plugs 301 and 303 and the pipes 281 and 283 is blocked as described above. For this reason, the MCH supplied to the pipe 281 does not leak through the insertion part 301. Even if there is a liquid containing toluene or the like inside the tube 283, the liquid will not leak through the plug-in portion 303.

  When the plug 330 is attached to the outlet 300, the plug 330 is inserted into the recess 310 with the end face 335 at the top, and is pushed in until the leaf springs 315 and 315 engage with the recesses 341 and 341 as shown in FIG. . At this time, the tube 337 is fitted on the insertion portion 301 and the shutter push-out bar 347 pushes the shutter 345 to open, so that the tube 337 and the tube 281 communicate with each other via the insertion portion 301. In addition, the tube 339 is fitted to the insertion portion 303 and the shutter push-out rod 349 pushes the shutter 397 to open, so that the tube 339 and the tube 283 communicate with each other through the insertion portion 303. As a result, the pipe 281 and the first tank 17 communicate with each other, and the pipe 283 and the second tank 19 communicate with each other.

  When the plug 330 is pulled out of the recess 310 against the engagement force between the leaf springs 315 and 315 and the recesses 341 and 341, the shutter push-out rods 347 and 349 are separated from the shutters 295 and 297, so that the shutters 295 and 297 are automatically used. Close.

2. Configuration of MCH Supply Facility 350 FIG. 12 is an explanatory diagram showing the configuration of the MCH supply facility 350 that supplies MCH to the pipe 281. As shown in FIG. 12, the MCH supply facility 350 has a configuration as a wind power generator in which a generator 354 is connected to a shaft 352 having a wind turbine 351 connected to one end via a clutch 353. The shaft 352 rotates integrally with the windmill 351. When the clutch 353 is in the connected state, the rotation of the shaft 352 is transmitted to the generator 354, and the generator 354 generates power.

  The rotation of the shaft 352 is transmitted to the crank 357 via the speed reducer 355. Note that the speed reducer 355 is a well-known device that can be adjusted in speed reduction rate by combining appropriate configurations from belts, gears, chains, and the like. The crank 357 reciprocates the first piston 362 inserted in the first cylinder 361 in accordance with the rotation of the crank 357 in the first cylinder 361, and the second piston 236 inserted in the second cylinder 363. The piston 364 is reciprocated in the second cylinder 363. Note that the crank 357 reciprocates the first piston 362 and the second piston 364 so that the phases thereof are different from each other by 180 °. Further, a heater 365 for heating the internal space of the first cylinder 361 is provided outside the first cylinder 361. A heater 366 that heats the internal space of the second cylinder 363 is provided outside the second cylinder 363.

  A first catalyst carrier 367 carrying the aforementioned dehydrogenation catalyst is inserted into the first cylinder 361. Regardless of the reciprocating motion of the first piston 362, the first catalyst carrier 367 has the dehydrogenation catalyst disposed in the entire space surrounded by the first piston 362 and the first cylinder 361. The dehydrogenation catalyst is supported on a metal configured in a spring shape. Inside the second cylinder 363, a second catalyst carrier 368 carrying the above-described hydrogenation catalyst is inserted. Regardless of the reciprocating motion of the second piston 364, the second catalyst carrier 368 is spring-shaped so as to be disposed in the entire space surrounded by the second piston 364 and the second cylinder 363. The hydrogenation catalyst is supported on the configured metal.

  In FIG. 12, the configurations of the first catalyst support 367 and the second catalyst support 268 are simplified, but the first catalyst support 367 and the second catalyst support 268 are meshed. It is desirable that the shape of the catalyst, such as a cotton shape, is such that the catalyst is more favorably disposed throughout the space. A heat pipe 369 is provided between the first cylinder 361 and the second cylinder 363.

  Further, the MCH supply facility 350 includes a hydrogen tank 371 that stores hydrogen in a high-pressure gas state, an MCH tank 372 that stores MCH, and a toluene tank 373 that stores a liquid containing toluene. Further, the MCH supply facility 350 includes pipes 374, 375, 376, 377, 378, 379 and valves 381, 382, 383, 386, 387, 388 in relation to the tanks 371-373. .

  The pipe 374 connects the inside of the first cylinder 361 and the hydrogen tank 371, and the valve 381 is opened or closed to permit or block the flow of fluid (mainly hydrogen) in the pipe 374. The pipe 375 connects the inside of the first cylinder 361 and the MCH tank 372, and the valve 382 is opened or closed to permit or block the flow of the fluid (mainly MCH) in the pipe 375. The pipe 376 connects the inside of the first cylinder 361 and the toluene tank 373, and the valve 383 is opened and closed to permit or block the fluid (mainly toluene) in the pipe 376.

  The pipe 377 connects the inside of the second cylinder 363 and the hydrogen tank 371, and the valve 386 is opened or closed to permit or block the fluid (mainly hydrogen) in the pipe 377. The pipe 378 connects the inside of the second cylinder 363 and the MCH tank 372, and the valve 387 is opened or closed to permit or block the flow of the fluid (mainly MCH) in the pipe 378. The pipe 379 connects the inside of the second cylinder 363 and the toluene tank 373, and the valve 388 is opened or closed to permit or block the flow of fluid (mainly toluene) in the pipe 379.

  As the crank 357 rotates and the internal volumes of the first cylinder 361 and the second cylinder 363 change, the valves 381 to 388 are opened and closed as follows. The valves 381 to 388 may be opened and closed by operation of a cam or the like as in a gasoline engine. When solenoid valves are employed as the valves 381 to 388, they may be opened and closed by computer control. It may be opened and closed. A part of the electric power generated by the generator 354 is also sent to a well-known electrolytic cell 390 that electrolyzes water into oxygen and hydrogen, and the hydrogen is sent to a hydrogen tank 371.

  As shown in FIG. 13, in the first cylinder 361, the reaction proceeds in the following two cycles. When the volume of the first cylinder 361 increases, the valves 381, 383 are closed and the valve 382 is opened. Then, MCH is sucked into the first cylinder 361 from the MCH tank 372 via the pipe 375. Note that the pipe 375 and the valve 382 have a certain flow path resistance, and at this time, the inside of the first cylinder 361 is in a reduced pressure atmosphere. Since the dehydrogenation reaction of MCH is promoted in a reduced-pressure atmosphere, the dehydrogenation reaction proceeds well if the interior of the first cylinder 361 is heated to an appropriate temperature by the heater 365.

  When the volume of the first cylinder 361 decreases, the valves 381, 383 are opened and the valve 382 is closed. Then, the liquid containing hydrogen and hydrogen generated by the dehydrogenation reaction are discharged from the first cylinder 361 through the pipes 374 and 376. The pipe 374 is connected to the uppermost part of the first cylinder 361 outside the reciprocating motion range of the first piston 362. On the other hand, the pipe 376 is connected to the lowermost portion outside the reciprocating motion range of the first piston 362 with respect to the first cylinder 361. For this reason, gaseous hydrogen is sent to the hydrogen tank 371 via the pipe 374, and a liquid containing toluene is sent to the toluene tank via the pipe 376. Needless to say, a gas-liquid separator may be provided between the pipes 374 and 376 to separate hydrogen and toluene better.

  In the inside of the first cylinder 361, in this way, every time the first piston 362 reciprocates due to the rotation of the crank 357, the suction and dehydrogenation reaction of MCH and the discharge of hydrogen and toluene are repeatedly executed. .

  In the second cylinder 363, the reaction proceeds in the following four cycles. First, when the volume of the second cylinder 363 increases (second cycle in FIG. 13), the valves 386 and 388 are opened and the valve 387 is closed. Then, hydrogen is sucked into the second cylinder 363 from the hydrogen tank 371 via the pipe 377 and liquid containing toluene is sucked from the toluene tank 373 via the pipe 379. The flow path resistances of the pipes 377 and 379 and the valves 386 and 388 are designed such that hydrogen and toluene are sucked into the second cylinder 363 at a ratio suitable for the hydrogenation reaction.

  Next, when the volume of the second cylinder 363 decreases, the valves 386, 387, and 388 are all closed. Then, hydrogen and toluene sucked into the second cylinder 363 in the previous cycle are placed in a pressurized atmosphere. Since the hydrogenation reaction of toluene is promoted in a pressurized atmosphere, the hydrogenation reaction proceeds well if the inside of the second cylinder 363 is heated to an appropriate temperature by the heater 366. At this time, an MCH dehydrogenation reaction takes place inside the first cylinder 361. The toluene hydrogenation reaction is an exothermic reaction, and the MCH dehydrogenation reaction is an endothermic reaction. For this reason, heat is exchanged between the first cylinder 361 and the second cylinder 363 via the heat pipe 369, and both reactions can proceed well.

  Next, when the volume of the second cylinder 363 increases, the valve 386 is opened and the valves 387 and 388 are closed. Then, hydrogen is sucked from the hydrogen tank 371 through the pipe 377. Then, the hydrogenation reaction with respect to unreacted toluene advances. However, hydrogen remains in the second cylinder 363 in a gas state to some extent.

  Next, when the volume of the second cylinder 363 decreases, the valve 387 is opened and the valves 386, 388 are closed. Here, the pipe 378 is connected to the lowermost part outside the reciprocating motion range of the second piston 364 with respect to the second cylinder 363. For this reason, when the volume of the second cylinder 363 decreases, the MCH generated by the hydrogenation reaction is discharged through the pipe 378 so as to be pushed out by the hydrogen remaining in the second cylinder 363, and the MCH tank 372. At this time, a part of hydrogen may be mixed into the MCH and sent to the MCH tank 372, but no major problem occurs. Rather, when unreacted toluene is sent to the MCH tank 372, a hydrogenation reaction may occur due to the mixed hydrogen.

  The speed reducer 355 adjusts the rotational speed of the crank 357 so that each reaction proceeds smoothly. The rotation speed of the crank 357 is also adjusted by connecting a generator 354 to the shaft 352 via the clutch 353. A part of the electric power generated when the generator 354 is connected to the shaft 352 is supplied to the electrolytic cell 390, and hydrogen generated according to the electric power supply is supplied to the hydrogen tank 371.

  The MCH tank 372 supplies MCH to the above-described pipe 281 through the pipe 397. The toluene tank 373 is supplied with a liquid containing toluene from the above-described tube 283 through the tube 398. Therefore, in the MCH supply facility 350, the cross-sectional areas of the first cylinder 361 and the second cylinder 363 are designed so that the reaction proceeds in the direction of converting toluene into MCH as a whole. And the hydrogen consumed at that time is replenished from the electrolytic cell 390 as mentioned above. Note that hydrogen may be supplied to the hydrogen tank 371 from a tank truck or the like. Further, the pair of pipes 397 and 398 is laid as a laying pipe 399 in the same manner as a city gas laying pipe under a road or the like.

3. Effects produced by the cartridge 253 and the MCH supply facility 350 (1) In the cartridge 253, by connecting the plug 330 to the outlet 300, the MCH is supplied in the same manner as when using city gas or electricity, and a liquid containing toluene is supplied. Can be discharged. For this reason, when the cartridge 253 is mounted on the terminal 1 or 201, it becomes easier to continue to use the terminal 1 or 201 continuously while maintaining the above-described effects described for the terminal 1 or 201 as they are.

  (2) In the MCH supply facility 350, the first piston 362 and the second piston 364 are reciprocated using wind power, and the heat pipe 369 is interposed between the first cylinder 361 and the second cylinder 363. Since heat is exchanged, toluene is efficiently converted to MCH. Therefore, the energy efficiency of the city provided with the MCH supply facility 350 and the laying pipe 399 can be improved.

4). Modification (1) The main process of the MCH supply facility 350 is a process of converting toluene into MCH. Therefore, the first cylinder 361 and the first piston 362 may be omitted. However, in that case, a plurality of second cylinders 363 and a plurality of second pistons 364 are provided in order to suppress variation in the rotational load of the crank 357 due to the rotation phase of the crank 357. It is desirable that the rotational phases are shifted by equal angles.

  (2) A plurality of the first cylinders 361 and the second cylinders 363 may be provided. Further, the first cylinder 361 and the second cylinder 363 may be replaced with the same configuration as the combustion chamber of the rotary engine.

  (3) The outlet 300 may be provided in a fuel cell vehicle that travels by acquiring hydrogen from the MCH and supplying it to the fuel cell. Moreover, the hose 270 may protrude directly into the cabin of such a fuel cell vehicle. That is, a fuel cell vehicle that travels by acquiring hydrogen from MCH includes a tank for supplying MCH and a tank for recovering a liquid containing toluene. Therefore, the fuel cell vehicle may be used like a tank truck that supplies MCH and collects a liquid containing toluene to the terminals 1, 201 or various devices having the same configuration.

(4) The crank 357 of the MCH supply facility 350 may be rotated by an internal combustion engine or may be rotated by human power. If the structure of the MCH supply facility 350 is reduced in size and mounted in a portable terminal 1 or the like, the liquid containing toluene in the second tank 19 is converted to MCH by turning the handle by hand and rotating the crank 357. Thus, it can be supplied to the first tank 17.

The sensor 27B and the notification device 420 are connected.

  When the main power supply of the terminal 201 is ON, the control unit 9 causes the CPU 45 to read the program stored in the ROM 47 so that the above-described processing of FIG. 5 and the processing shown in the flowchart of FIG. Is done.

  In the process of FIG. 16, first, in S61, the water amount Lm of the water tank 27 is acquired via the water amount sensor 27B. In continuing S63, it is judged whether the water quantity Lm acquired by S61 is more than the preset upper limit.

In S64, it is notified that the water is full via the notification device 420, and the process is temporarily ended.

3. Effects produced by the terminal 401 (1) Also in the terminal 401, the process of FIG. 5 similar to that of the terminal 1 is performed, so that the dehydrogenation reaction in the dehydrogenation reactor 21 reduces the storage amount CH of the storage battery 8 to the lower limit value and the upper limit value. It is executed only to the extent necessary and sufficient to maintain between. Therefore, it is not necessary to provide a hydrogen storage unit such as a buffer tank in the terminal 401. Therefore, the safety of the terminal 401 is improved, and the terminal 401 can be reduced in size favorably.

  (2) In the terminal 401, when the notification is made by the notification device 420, the owner opens the valve 411 and discharges the water inside the water tank 27 to the outside, so that the water tank 27 can be fully filled. it can. Accordingly, the configuration of the terminal 401 is further simplified, the manufacturing cost is further reduced, and the miniaturization is further facilitated.

4). Modifications (1) The notification device 420 can be replaced with a device that notifies the owner by various methods such as voice and low-frequency stimulation in addition to a device that notifies by vibration. Moreover, when the water accommodated in the water tank 27 can be used as drinking water, a drinking mouth may be provided in a portion exposed to the outside of the terminal 401 of the drain pipe 410.

<Fourth Embodiment>
1. Configuration of Terminal 501 A configuration of a terminal 501 that is an embodiment of the power supply apparatus will be described with reference to FIG. Note that the terminal 501 is configured in the same manner as the terminal 1 in many parts. Therefore, in the terminal 501, the same reference numerals used in FIGS. 1 to 6 are used in FIG. 17 for the parts configured similarly to the terminal 1, and detailed description is omitted, and only the differences are described.

  As shown in FIG. 17, the terminal 501 does not have a configuration in which the adsorber 25 and the water tank 27 are housed in the cartridge 153, similarly to the terminal 401. It is attached to. Note that at least one of the adsorber 25 and the water tank 27 may not be replaceable. Further, the terminal 501 includes an electrolytic cell 530 (an example of a water treatment unit), an ozone water tank 533, a pump 534, and pipes 535, 536, 537, and 538 in the hydrogen supply unit 3.

  The electrolytic cell 530 is a well-known one that electrolyzes water to generate ozone water and hydrogen as described in, for example, Japanese Patent Application Laid-Open No. 2005-336607. That is, the electrolytic cell 530 is provided with an anode chamber and a cathode chamber (not shown) with a solid polymer film sandwiched therebetween, and a porous or mesh-like anode (not shown) is provided on the surface of the solid polymer film on the anode chamber side. A porous or reticulated cathode (not shown) is provided on the surface of the solid polymer film on the chamber side. For example, Nafion (registered trademark) is used as the solid polymer film. In such an electrolytic cell 530, water containing hydrogen gas is supplied to the cathode chamber and water containing hydrogen gas is supplied to the anode chamber by supplying water to the anode chamber and the cathode chamber and applying an appropriate voltage between the anode and the cathode. Ozone water is generated respectively.

  The pipe 535 connects the electrolytic cell 530 and the water tank 27. The pipe 535 is branched in two on the electrolytic cell 530 side so that water can be supplied to the anode chamber and the cathode chamber of the electrolytic cell 530, respectively. A pump 534 is provided on the upstream side of the water flow direction.

  The pipe 356 connects the cathode chamber of the electrolytic cell 530 and the ozone water tank 533. The pipe 537 branches from a branch portion 539 provided in the middle of the pipe 536 and is connected to the pipe 35. The pipe 538 connects the pipe 536 between the branch part 539 and the ozone water tank 533 and the anode chamber of the electrolytic cell 530.

  Therefore, when the pump 534 is energized, the water in the water tank 27 is supplied to the anode chamber and the cathode chamber of the electrolytic cell 530, and at that time, the current is energized between the anode and the cathode of the electrolytic cell 530. If so, ozone water is generated in the anode chamber, and water and hydrogen are generated in the cathode water. The branch part 539 is configured such that the pipe 537 is disposed upward in the gravity direction and the pipe 536 is disposed horizontally or downward in the gravity direction. For this reason, the hydrogen generated in the cathode chamber is sent to the pipe 35 via the pipe 536, the branch portion 539, and the pipe 537 in this order. Then, the hydrogen is used for power generation in the fuel cell 5 as described above.

  Further, the water sent out from the cathode chamber of the electrolytic cell 530 is sent to the ozone water tank 533 through the pipe 536. At that time, the ozone water sent out from the anode chamber through the pipe 538 joins the water sent out from the cathode chamber, and the ozone water tank 533 is made into ozone water having an ozone concentration suitable for washing the body and dishes. Is housed in. The ozone concentration of the ozone water can be adjusted by adjusting the voltage applied to the electrolytic cell 530 and the water supply speed by the pump 534.

  In the terminal 501, the water tank 27 is provided with a water amount sensor 27 </ b> B that detects the amount of water inside the water tank 27. The ozone water tank 533 includes an ozone water sensor 533A for detecting the amount of ozone water inside the ozone water tank 533, and a drain pipe for discharging ozone water inside the ozone water tank 533 to the outside of the terminal 501. 540. Further, the drain pipe 540 is provided with a valve 541 that opens or closes to permit or block the flow of water in the drain pipe 540. The valve 541 is a valve that can be manually opened and closed. Further, similarly to the terminal 401, the terminal 501 is provided with a notification device 420 that notifies the owner by vibration.

2. Processing Performed by Terminal 501 FIG. 18 is a block diagram showing the configuration of the control system of terminal 501. As shown in FIG. 15, the input unit 11, the HDD 13, the display 15, the heater 21 </ b> A, the pumps 29 and 31, and the charged amount sensor 8 </ b> A are connected to the control unit 9 of the terminal 501, as well as the terminal 1. Sensor 27B, notification device 420, ozone water sensor 533A, and pump 534 are connected.

  When the main power supply of the terminal 201 is ON, in the control unit 9, the CPU 45 reads out the program stored in the ROM 47, so that the process of FIG. 5 and the process shown in the flowchart of FIG. Is done.

  In the process of FIG. 19, first, in S71, the water amount Lm of the water tank 27 is acquired via the water amount sensor 27B, and the ozone water amount Lo of the ozone water tank 533 is acquired via the ozone water sensor 533A. In subsequent S72, it is determined whether or not the amount of ozone water Lo acquired in S71 is equal to or greater than a preset upper limit value. When the amount of ozone water Lo is less than the upper limit value (S72: N), the process proceeds to S73.

  In S73, it is determined whether or not the amount of water Lm acquired in S71 is greater than or equal to a preset lower limit value. When the amount of water Lm is less than the lower limit (S73: N), the process proceeds to S75. In S75, energization to the electrolytic cell 530 and the pump 534 is stopped, whereby water flow to the electrolytic cell 530 is stopped, and electrolysis in the electrolytic cell 530 is stopped. Note that the lower limit value is set as the lower limit water amount at which water in the water tank 27 can be sent to the electrolytic cell 530 and electrolysis can be performed. In addition, when energization to the electrolytic cell 530 and the pump 534 has already been stopped at the time when the process proceeds to S75, the energization stop is continued in S75.

  On the other hand, when it is determined in S73 that the water amount Lm is equal to or greater than the lower limit (S73: Y), the process proceeds to S77. In S77, energization to the electrolytic cell 530 and the pump 534 is started, whereby water flow to the electrolytic cell 530 is started, and electrolysis in the electrolytic cell 530 is started. In addition, when the energization to the electrolytic cell 530 and the pump 534 has already been started when the process proceeds to S77, the energization is continued in S77.

  If it is determined in S72 that the amount of ozone water Lo is equal to or greater than the upper limit (S72: Y), the process proceeds to S78. In S78, it is notified that the water is full via the notification device 420. In subsequent S79, energization to the electrolytic cell 530 and the pump 534 is stopped as in S75, and the process is temporarily ended.

3. Effects produced by the terminal 501 (1) Also in the terminal 501, the dehydrogenation reaction in the dehydrogenation reactor 21 is performed by setting the storage amount CH of the storage battery 8 to the lower limit value and the upper limit value by performing the same processing as FIG. It is executed only to the extent necessary and sufficient to maintain between. Therefore, it is not necessary to provide a hydrogen storage unit such as a buffer tank in the terminal 501. Therefore, the safety of the terminal 501 is improved, and the terminal 501 can be reduced in size favorably.

  (2) In the terminal 501, since the water inside the water tank 27 is sent to the electrolytic cell 530, the water tank 27 can be prevented from becoming full. And the ozone water produced | generated in the electrolytic vessel 530 is discharged | emitted outside via the drain pipe 540, when an owner opens the valve 541 as needed. For this reason, the owner can use the ozone water for disinfection and sterilization of the body and tableware.

  (3) When notification by the notification device 420 is made, the owner opens the valve 541 and discharges the ozone water inside the ozone water tank 533 to the outside, so that the ozone water tank 533 can be filled up. . As the ozone water is discharged in this way, the amount of ozone water Lo becomes less than the upper limit value (S72: N), the electrolysis of the water in the water tank 27 is resumed (S77), and the water tank 27 becomes full. It is also suppressed.

  (4) The terminal 501 can electrolyze the water stored in the water tank 27 and supply the obtained hydrogen to the fuel cell 5 again. Therefore, the number of replacements of the cartridge 53 is reduced, and the maintenance of the terminal 501 becomes easier. Note that a gas-liquid separator similar to the gas-liquid separator 23 may be provided in the branch portion 539 so that the gas component (hydrogen) may be sent to the pipe 37. In that case, hydrogen obtained by electrolysis may be able to be recovered more efficiently.

4). Modifications (1) In the terminal 501 as well as the terminal 401, the notification device 420 can be replaced with a device that notifies the owner by various methods such as voice and low-frequency stimulation in addition to a device that notifies by vibration. .

  (2) Similarly to the terminal 1, the terminal 501 can be various terminals such as a stationary terminal such as a desktop personal computer and an in-vehicle car navigation system, and a portable terminal such as a notebook personal computer and a mobile phone. Further, the configuration of the power supply device in the terminal 501 (hydrogen supply unit 3, fuel cell 5, storage battery 8, control unit 9, drain pipe 540, and valve 541) includes a mobile phone charger and an electric vehicle (hybrid vehicle). And other various devices such as household appliances.

(3) The electrolytic cell 530 may be replaced with one that electrolyzes water into gaseous oxygen and hydrogen. In that case, configurations such as the ozone water tank 533 and the pipe 536.553738 are unnecessary, and the apparatus can be further downsized. However, in that case, it is impossible to generate ozone water at the terminal 501.
<Other embodiments>
(1) The present invention is not limited to the above-described embodiment, and can be implemented in various forms without departing from the gist of the present invention. For example, the configurations of the terminals 1 to 501 and the modifications thereof can be appropriately combined or partly omitted. Further, the pump 31 may be omitted. In this case, whether or not hydrogen is supplied to the fuel cell 5 varies depending on the reaction state in the dehydrogenation reactor 21, but there is a margin in the upper limit value and lower limit value of the storage amount CH in the process of FIG. 5 or FIG. If it has, it will be difficult to cause a big problem. In addition to MCH, various organic hydrides such as cyclohexane, decalin, and methyl decalin can be used as the organic hydride. Even in that case, dehydrogenation can be performed in the dehydrogenation reactor 21.

  (2) Further, in the terminals 1 to 501 and the modifications thereof, the storage battery 8 may be capable of storing power from an external power source such as a commercial AC power source or a car cigarette lighter. In particular, when the water stored in the water tank 27 is used as drinking water or used as ozone water, there is also a usage method in which the storage battery 8 is charged from an external power source for the purpose of generating the drinking water or ozone water. Conceivable.

  (3) Moreover, as shown in FIG. 20, the water accommodated in the water tank 27 may be sent to the following heat sink 700, and may be used for cooling CPU45 grade | etc.,. The heat sink 700 (an example of a water treatment unit) has a water tank 703 inside a base 702 on which a large number of fins 701 are erected in the same manner as a general heat sink. Further, a capillary 705 communicating with the inside of the water tank 703 is formed in a tree shape on the fin 701, and the capillary 705 opens on the surface of the fin 701. The water tank 27 and the water tank 703 are connected by a pipe 741, and a pump 743 is provided in the pipe 741.

  For this reason, the water accommodated in the water tank 27 is sent to the water tank 703 via the pipe 741 by the pump 743. The water sent to the water tank 703 reaches the surface of the fin 701 through the capillary tube 705 and vaporizes, thereby cooling the CPU 45. Further, the vaporization is promoted by the generation of the CPU 45. The driving power of the pump 743, that is, the water supply speed to the water tank 703 may be controlled to be proportional to the amount of heat generated by the CPU 45.

  Therefore, when such a heat sink 700 is used, the water stored in the water tank 27 can be vaporized to prevent the water tank 27 from becoming full, and the CPU 45 can be cooled at the same time. The heat sink 700 may be provided in the storage battery 8 and used to cool the storage battery 8. In the MCH production unit 240, an exothermic reaction occurs as described above. Therefore, if the heat sink 700 is provided in the MCH production unit 240, the water stored in the water tank 27 can be efficiently vaporized. Furthermore, when the fins 701 of the heat sink 700 are arranged so as to be exposed to the room, water vapor is emitted from the openings of the capillaries 705 in the fins 701, so that the room can be humidified.

  Note that various configurations other than the configuration of the heat sink 700 can be applied as the configuration for cooling the CPU 45 and the like using the water stored in the water tank 27. For example, the CPU 45 may be water-cooled by providing a pipe around the CPU 45 and circulating the water through the pipe.
