Description

  The present invention relates to a heating system for heating a hydrogen gas generation unit for generating hydrogen gas to be supplied to a fuel cell, and an electromagnetic induction heating unit and a hydrogen gas generation system used in this system.

  A fuel cell is an energy source that is attracting attention because it has higher power generation efficiency than other power generation systems and does not generate substances that pollute the atmosphere. In order to generate power in the fuel cell, air (oxygen) is supplied to the cathode and hydrogen is supplied to the anode. Hydrogen becomes hydrogen ions and electrons by the catalytic reaction at the anode, and the hydrogen ions move through the electrolyte and react with oxygen by the catalytic reaction at the cathode to become water. On the other hand, the electrons travel through the external circuit and move to the cathode. Electric energy is generated by the movement of the electrons.

  As described above, it is necessary to supply hydrogen as a fuel to the fuel cell. Accordingly, various apparatuses for generating hydrogen are known and disclosed in, for example, Patent Documents 1 and 2 below. These all generate hydrogen by decomposing hydrocarbons. The hydrogen generators in Patent Documents 1 and 2 are constituted by a cylindrical reactor as well as a cylindrical heat supply device.

  In addition, a hydrogen gas generation unit disclosed in Patent Document 3 below includes a tank for containing water, a reaction vessel containing a metal that generates hydrogen by a chemical reaction with water, and a proximity to the reaction vessel. Heating means, an introduction pipe for introducing water contained in the tank into the reaction container, a return pipe for introducing hydrogen generated in the reaction container and unreacted water into the tank, hydrogen in the tank and And a discharge pipe for discharging water.

  In the case of these hydrogen gas generation units, in order to efficiently perform the reaction in the reaction vessel, it is necessary to heat to a temperature suitable for the reaction. For this purpose, a heating means is also provided in the prior art. In Patent Document 3, it is disclosed that a heater by resistance heating, a positive temperature coefficient thermistor, a heater using oxidation heat of chemical reaction, a heater by catalytic combustion, or a heater by induction heating is used as this heating means. Yes. In Patent Document 3, in order to start the operation of the hydrogen gas generation unit, a reaction vessel (corresponding to a hydrogen generation unit) for generating hydrogen gas is mounted between a pair of heating means. By heating by this heating means, water vapor and metal are chemically reacted to generate hydrogen gas, which is supplied to the fuel cell. When the metal in the reaction vessel is oxidized and the generation efficiency of hydrogen gas decreases, the operation of the hydrogen gas generation unit is stopped and the reaction vessel is taken out between the pair of heating means. Then, a new metal is filled in the reaction container and then mounted again. In this way, the generation of hydrogen gas by the hydrogen gas generation unit can be continued.

  On the other hand, the fuel cell can be used for various electronic devices, for example, it can be used as a power source for notebook computers. In this case, it is preferable that the fuel battery cell and the hydrogen gas generation unit are separately installed in a notebook computer, and only the hydrogen gas generation unit is detachable from the notebook computer. This is because when metal or water used for a chemical reaction that generates hydrogen gas is consumed, it is necessary to replace them with new ones. Moreover, in order to start the chemical reaction in the hydrogen gas generation unit, it is necessary to heat the chemical reaction efficiently. In this case, it can be heated by driving a heater provided in the notebook computer, but if the notebook computer is not used for a long time, it may not be heated by the heater inside the notebook computer. This is because the secondary battery provided in the notebook computer is not charged, and the heater cannot be driven by the secondary battery. Therefore, in such a case, there is a problem that it is difficult to smoothly start up the hydrogen gas generation unit.

In the system disclosed in Patent Document 3, the reaction vessel is configured to be detachable with respect to the heating means, but it is always used together with the heating means except when filling with metal. Therefore, it is inconvenient to be incorporated into a small device such as a notebook personal computer, and even if it is incorporated, there remains a problem when it is not used for a long time. Although only a hydrogen gas generation unit can be installed separately from the notebook computer and heated using a commercial power supply, it is difficult to use.

  The present invention has been made in view of the above circumstances, and its problem is to provide a heating system for a hydrogen gas generation unit, an electromagnetic induction heating unit, and a hydrogen gas generation unit for efficiently starting a hydrogen gas generation unit mounted on a device. Is to provide.

In order to solve the above problems, a heating system for a hydrogen gas generation unit according to the present invention includes:
A heating system for heating a hydrogen gas generation unit for generating hydrogen gas to be supplied to a fuel cell,
A hydrogen generation unit provided in the hydrogen gas generation unit for generating hydrogen gas by a chemical reaction;
A hydrogen gas generation unit is detachably formed, and an electromagnetic induction heating unit for heating the hydrogen generation unit;
And a control unit that detects that the hydrogen generating unit is heated to a predetermined temperature and displays the hydrogen generating unit externally.

  The operation and effect of the heating system having such a configuration will be described. The hydrogen gas generation unit includes a hydrogen generation part and has a function of generating hydrogen gas by a chemical reaction. For example, hydrogen gas can be generated by reacting pure iron and water vapor, but heating is necessary to efficiently perform this chemical reaction. Therefore, an electromagnetic induction heating unit is provided, and the hydrogen gas generation unit is detachable. For example, when used for a notebook computer, the hydrogen gas generation unit is removed from the notebook computer, and this unit is attached to the electromagnetic induction heating unit. If a hydrogen gas generation unit is attached to the electromagnetic induction heating unit, the hydrogen generation unit can be heated to start a chemical reaction efficiently. Further, it is possible to detect that the hydrogen generating part has been heated to a predetermined temperature and display that the predetermined temperature has been reached. Based on this display, the hydrogen gas generation unit can be removed from the electromagnetic induction heating unit and mounted again on a device such as a notebook computer. As a result, it is possible to provide a hydrogen gas generation unit that efficiently activates the hydrogen gas generation unit mounted on the device.

  The hydrogen gas generation unit according to the present invention preferably includes a heat insulating portion that covers the periphery of the hydrogen generating portion. When heating by the heating means is performed, the structure in which the heat easily escapes to the outside reduces the heating efficiency and consumes useless energy. For example, the appropriate temperature when hydrogen gas is generated by reacting iron and water is 100 ° C. to 300 ° C., but it is desirable that the temperature be as close to 300 ° C. as possible in order to perform the reaction efficiently. Therefore, a structure that does not allow heat to escape is required. Then, it can be set as the structure which heat does not escape by providing the heat insulation part which covers the circumference | surroundings of a hydrogen generation part.

  It is preferable that the hydrogen generation unit is configured to be detachable from the heat insulating unit. When the metal material filled in the hydrogen generation unit is exhausted, the hydrogen generation unit can be attached or detached easily so that a new metal material can be filled or a new hydrogen generation unit can be attached (replaced). it can.

  The heat insulating part according to the present invention is preferably vacuum heat insulating. For example, the heat insulation part can be formed inside the housing part by evacuating the inside of the housing part. Thereby, the heat which heated the hydrogen generating part can be made hard to be transmitted outside.

  In the present invention, it is preferable that a heater is disposed at a boundary portion between the heat insulating portion and the hydrogen generating portion. The start-up of the hydrogen gas generation unit is performed by an electromagnetic induction heating unit, but is performed by a heater after the hydrogen gas generation unit is once mounted on the device. This heater can be efficiently heated by the heater by being arranged at the boundary between the heat insulating portion and the hydrogen generating portion.

  In the present invention, it is preferable that the cover member constituting the hydrogen generating part is made of a metal material that is easily heated by electromagnetic induction, and the cover member constituting the heat insulating part is made of a material that is not heated or hardly heated by electromagnetic induction.

  When the hydrogen gas generation unit is heated, it becomes difficult to touch with a hand if the cover member becomes hot. Therefore, the cover member constituting the hydrogen generating part is made of a material that is easily heated by electromagnetic induction (for example, stainless steel), and the cover member constituting the heat insulating part is made of a material that is not heated by electromagnetic induction or is hardly heated (for example, aluminum). To do. Thereby, since the outermost cover member is not heated by the electromagnetic induction heating unit (it is difficult to be heated), it can be easily touched by hand and can be easily attached to the device.

  A preferred embodiment of a heating system for a hydrogen gas generation unit according to the present invention will be described with reference to the drawings. First, a configuration example when a fuel cell module including a hydrogen gas generation unit is mounted on a notebook computer will be described with reference to FIG.

<Installation of fuel cell in notebook computer>
In FIG. 1, the notebook computer includes a fixed main body portion 10 and a movable main body portion 11, and the movable main body portion 11 is attached to the fixed main body portion 10 so as to be openable and closable. The movable main body 11 is opened. The movable main body 11 is supported by two hinge portions 12 so as to be rotatable with respect to the fixed main body 10. Inside the fixed main body 10, a CPU and a memory as a computer control unit, a mother board on which these are mounted, a hard disk and a controller thereof, a device for driving an external storage medium, and the like are incorporated. A liquid crystal display panel 14 is mounted on the movable main body 11 as a display panel. In order to connect the wiring for driving the liquid crystal display panel 14 from the fixed main body 10, the wiring connection portion 13 is also provided.

  The notebook computer of this embodiment can be driven not only by a commercial power supply but also by a fuel cell module mounted inside the notebook computer. The fuel cell module includes a power generation unit 20 mounted on the back side of the liquid crystal display panel 14 of the movable main body 11, a hydrogen gas generation unit 21 mounted at an appropriate location in the fixed main body 10, and a hydrogen gas generation unit. A gas supply tube 22 (corresponding to a gas supply path) for supplying the fuel gas generated by 21 to the power generation unit 20 is provided. The gas supply tube 22 is connected via the wiring connection portion 13. The hydrogen gas generation unit 21 is detachably attached to the fixed main body 10.

<Fuel cell module>
FIG. 2 is a diagram showing the configuration of the fuel cell module. As already described, the fuel cell module includes the power generation unit 20 mounted on the movable main body 11 and the hydrogen gas generation unit 21 mounted on the fixed main body 10. The power generation unit 20 has eight fuel cells S arranged in a plane and is connected to a circuit board 23 (corresponding to a flat support board). The fuel cell S has a flat plate shape, and by arranging the fuel cells S in a plane, the output voltage can be increased and the entire power generation unit 20 can be reduced in thickness. In the present invention, the number of fuel cells S to be mounted can be determined as appropriate.

  An electronic circuit is mounted on the surface of the circuit board 23 opposite to the surface on which the fuel cell S is mounted, and a booster circuit and a constant voltage circuit are mainly mounted. Since the electrical output from one fuel cell S is very small, the output voltage can be increased by connecting a plurality of fuel cells S in series. By further boosting this output voltage, a voltage value suitable for driving the computer can be obtained. Moreover, since the output of the fuel cell S is not stable, a stable voltage can be supplied to the computer by providing a constant voltage circuit for stabilizing the output. The circuit board 23 is provided with electrodes (positive electrode and negative electrode) (not shown), and power is supplied to the computer through these electrodes.

<Configuration of hydrogen gas generation unit>
Next, the configuration of the hydrogen gas generation unit 21 will be described with reference to FIGS. The hydrogen gas generation unit 21 is configured to be detachable from the notebook computer. Pure iron and water are used to generate hydrogen gas, but these are consumables and need to be replaced with new ones. In order to facilitate the work for that, only the hydrogen gas generation unit 21 is configured to be removable from the notebook computer.

  The hydrogen gas generation unit 21 is roughly composed of a hydrogen generation unit 30 and a vacuum heat insulation unit 31. As shown in FIG. 4, the hydrogen generating unit 30 is configured to be detachable from the vacuum heat insulating unit 31. As described above, when exchanging consumables or the like, only the hydrogen generating unit 30 is removed from the vacuum heat insulating unit 31. This is because the vacuum heat insulating portion 31 is not a consumable item and need not be replaced with a new one. When pure iron or water is consumed (pure iron becomes iron oxide), the entire hydrogen generating unit 30 is replaced with a new one, or only pure iron and water are replaced. Even when the entire hydrogen generation unit 30 is replaced, the old hydrogen generation unit 30 is not discarded but is reused. Iron oxide can be returned to the original pure iron by reduction.

  The hydrogen generation unit 30 includes an iron storage unit 32 and a water storage unit 33. The iron container 32 is filled with pure iron powder or pure iron tablet. The tablet is obtained by putting pure iron powder in a mold and compression molding. A connection tube 34 connected to the gas supply tube 22 on the notebook computer side is attached to the upper portion of the iron housing portion 32. The distal end portion 21 a of the connection tube 34 is connected to the gas supply tube 22. When the hydrogen gas generation unit 21 is detached from the notebook computer, it is preferable that the tip end portion 21a is closed.

  Absorbent cotton 35 is provided on the opposite side of the iron accommodating portion 32 from the connection tube 34. This absorbent cotton 35 functions as a water holding member. A space in which the absorbent cotton 35 is provided and a space in which pure iron is enclosed are partitioned by a net-like member 36. Thereby, the pure iron in the iron accommodating part 32 is prevented from moving to the absorbent cotton 35 side. An opening 37 is formed so that water is supplied to the absorbent cotton 35. The water enclosed in the water storage unit 33 is supplied through the opening 37. The water accommodation part 33 is arranged so as to cover almost the entire periphery of the iron accommodation part 32. In addition, arrangement | positioning of the water accommodating part 33 is not limited to this. The cover member 38 constituting the water accommodating part 33 and the cover member 39 constituting the iron accommodating part 32 are formed of a magnetic material such as stainless steel. This corresponds to a metal material that is easily heated by electromagnetic induction heating. Examples of preferable metal materials other than stainless steel include iron, iron-based alloys, nickel, and nickel-based alloys.

  A lid 40 is provided around the connection tube 34 of the hydrogen generator 30, and the internal space 40 a of the lid 40 constitutes a heat insulating part by vacuum heat insulation. As a result, the heat generated when the hydrogen generating unit 30 is heated has a structure in which it is difficult to escape to the outside easily. The cover member 41 constituting the lid 40 is made of a nonmagnetic material such as aluminum so that heating by electromagnetic induction is not performed. Thereby, it is set as the structure which heat does not escape from the hydrogen generating part 30 easily. Preferable materials other than aluminum include titanium, ceramic, heat resistant resin and the like.

  The vacuum heat insulation part 31 is arrange | positioned so that the circumference | surroundings (except the part in which the cover part 40 is provided) of the hydrogen generation part 30 may be covered, and the internal space 31a is vacuum-insulated. The vacuum heat insulating part 31 is formed with an accommodation recess 31 b for accommodating the hydrogen generation part 30. The housing recess 31b is set to have a slightly larger size than the hydrogen generator 30. A film heater 42 is attached to the inner wall surface of the housing recess 31b. The film heater 42 has a function of performing a heating action on the hydrogen generator 30. By using the film heater 42, the thickness can be reduced, and there is no problem when the film heater 42 is attached to a notebook computer. A heating circuit for driving the film heater 42 is provided inside the notebook computer, and a terminal (not shown) for connection to the heating circuit is provided in the vacuum heat insulating portion 31. That is, the film heater 42 is driven only when the hydrogen gas generation unit 21 is attached to the notebook computer. The cover member 43 constituting the vacuum heat insulating portion 31 is preferably made of a nonmagnetic metal such as aluminum. Thereby, it is possible to prevent the vacuum heat insulating portion 31 from being heated by electromagnetic induction.

  Next, a chemical reaction when generating hydrogen gas in the hydrogen generator 30 will be described. Pure hydrogen is generated by reacting pure iron accommodated in the iron accommodating part 32 with water or water vapor. The generated hydrogen is supplied to the fuel cell S through the gas supply tube 22 connected to the connection tube 34.

The chemical reaction for generating hydrogen is as shown in the following formula.
[Chemical 1]
4H ₂ O + 3Fe → Fe ₃ O ₄ + 4H ₂
That is, when water (steam) is supplied to pure iron, they react to produce iron oxide and hydrogen gas. This chemical reaction does not generate gases that adversely affect the environment, such as carbon dioxide and carbon monoxide. In other words, it can be said that it is clean energy. Only hydrogen gas (pure hydrogen) is supplied to the fuel cell S. Although water is accommodated in the water accommodating part 33, it is possible to generate water vapor by heating and supply it to the iron accommodating part 32.

  The chemical reaction in the iron accommodating part 32 is performed at about 100 ° C to 400 ° C. In order to make the iron accommodating part 32 become the said temperature range, the film heater 42 mentioned above is provided. The film heater 42 has the purpose of accelerating the reaction between pure iron and water vapor, and the purpose of changing the water in the water storage part 33 to water vapor.

<Heating system for hydrogen gas generation unit>
Next, a system for heating the hydrogen gas generation unit will be described. In order to generate hydrogen gas in the hydrogen gas generation unit 21, heating is performed by the film heater 42. However, when the hydrogen gas generation unit 21 is started up after the notebook personal computer is not used for a long time, heating by the film heater 42 is performed. There are things you can't do. For example, the secondary battery provided in the notebook computer is not stored and cannot be used. In such a case, a heating system for smoothly starting up the hydrogen gas generation unit 21 is required. Therefore, a heating system using an electromagnetic induction heating unit 50 as shown in the embodiment of FIG. 5 is used.

  An electromagnetic coil 45 is provided as a heating means for heating the hydrogen generator 30. The electromagnetic coil 45 is accommodated in the accommodation case 46. The housing case 46 is formed with a housing recess 46a, and the hydrogen gas generation unit 21 can be inserted detachably. The size of the housing recess 46 a is set to be slightly larger than the outer size of the hydrogen gas generation unit 21. The electromagnetic induction heating unit 50 is provided with an outlet for connection to a commercial power source, and can be handled in the same manner as a charger for home appliances, for example.

  The drive circuit 47 is configured by an electronic circuit or the like for driving the electromagnetic coil 45. The mounting sensor 48 is a sensor that detects that the hydrogen gas generation unit 21 is mounted on the electromagnetic induction heating unit 50. For example, it is composed of a reflective optical sensor. The attachment detection unit 49 detects whether or not the hydrogen gas generation unit 21 is attached based on the detection result of the attachment sensor 48. The timer setting unit 54 is provided to detect that the hydrogen generating unit 30 is heated to a predetermined temperature, and predetermined time data is set. When it is detected that the hydrogen gas generation unit 21 is mounted, the controller 51 gives a command to the drive circuit 47 to drive the electromagnetic coil 45.

  The display lamp 53 displays that the hydrogen gas generation unit 21 has been installed or that the hydrogen generation unit 30 has reached a predetermined temperature. As the display lamp 53, for example, an LED can be used. The display drive circuit 52 is configured by an electronic circuit or the like for performing display control of the display lamp 53. The control unit 51 can perform display control for the display lamp 53 based on the mounting detection unit 49 and the timer setting unit 54. The display form (for example, lighting and blinking) of the display lamp 53 is controlled so as to change according to the contents to be displayed.

<Heating operation>
Next, the operation when the hydrogen generating unit 30 is heated using the heating system of the hydrogen gas generating unit shown in FIG. 5 will be described. The hydrogen gas generation unit 21 is taken out from the notebook computer and attached to the electromagnetic induction heating unit 50. When the mounting is completed, the mounting sensor 48 detects the hydrogen gas generation unit 21 and starts driving the electromagnetic coil 45. At the same time, the display lamp 53 is displayed blinking, for example. This blinking display shows that the hydrogen generating unit 30 is being heated. Since the cover members 38 and 39 of the hydrogen generating unit 30 are made of stainless steel, they are heated by the electromagnetic coil 45, but the cover member 43 of the heat insulating unit 31 is made of aluminum and thus hardly heated. Thereby, only the hydrogen generation part 30 in the hydrogen gas generation unit 21 can be heated.

  The water in the water storage portion 33 is heated by the heating of the electromagnetic coil 45 and becomes water vapor. This water vapor is supplied to the iron accommodating part 32 and reacts with pure iron. Thereby, hydrogen gas is generated. Since the heating by the electromagnetic coil 45 is transmitted also to the iron accommodating part 32, the chemical reaction which generates hydrogen gas can be performed efficiently. When the predetermined time set in the timer setting unit 54 arrives, the control unit 51 gives a command to the drive circuit 47 so as to stop the heating by the electromagnetic coil 45. A command is also given to the display drive circuit 52 to switch the display mode of the display lamp 53 from blinking to lighting. Thereby, it can be recognized that the heating has ended. Therefore, the hydrogen gas generation unit 21 is taken out from the electromagnetic induction heating unit 50 and attached to the notebook computer again. At this time, since the outermost cover member 43 is not (almost) heated, there is no problem even if it is touched by hand.

  Once attached to the notebook computer, the hydrogen generator 30 can be heated by the film heater 42. If the notebook personal computer has not been used for a long time, the hydrogen gas generation unit 21 may be taken out again and set in the electromagnetic induction heating unit 50.

  Further, when pure iron or water in the hydrogen gas generation unit 21 is consumed, as shown in FIG. 4, only the hydrogen generation unit 30 may be taken out and replaced with a new one.

<Another embodiment>
In the present embodiment, the configuration example when the fuel cell is used in a notebook computer has been described. However, the present invention is not limited to this, and the present invention can also be applied when used in any device other than a notebook computer. It is. The fuel cell S shown in FIG. 2 shows an example, and the present invention can be applied to other types of fuel cells.

  The configuration of the hydrogen gas generation unit is not limited to that of this embodiment. For example, the overall shape of the hydrogen gas generation unit 21 is arbitrary, and can be a shape that matches the equipment, such as a rectangular parallelepiped, a cube, or a cylinder. In the case of a portable device such as a notebook computer, a thin rectangular parallelepiped (flat plate) is preferable. The shape of the hydrogen generation unit 30 and the shapes of the iron storage unit 32 and the water storage unit 33 may be arbitrary. You may comprise the iron accommodating part 32 and the water accommodating part 33 so that each can be replaced | exchanged independently. The structure which connects the iron accommodating part 32 and the water accommodating part 33 with a pipe may be sufficient. Further, a pump may be provided on the pipe path to supply water. When heating water and supplying with water vapor | steam, it can supply with water vapor pressure.

  The display location of the display lamp 53 is not limited to that shown in FIG. The mounting sensor 48 may also be installed at a place other than the bottom of the housing recess 46a.

  In the present embodiment, the detection of the predetermined temperature is performed based on the time set in the timer setting unit 54. Alternatively, the temperature of the hydrogen generation unit 30 may be detected by a temperature sensor.
