2. Description of the Related Art In a fuel cell, a pair of electrodes are provided on both sides of an electrolyte which is an ion conductor, and one electrode (usually called an "air electrode") is provided with an oxidant (oxygen, air, or the like). A device that supplies air or oxygen-rich air and supplies a reducing agent (hydrogen or a hydrogen-containing component) to the other electrode (usually called a “fuel electrode”) to electrochemically generate power. And uses the reverse principle of electrolysis of water. In general, hydrogen is supplied to the fuel electrode by mixing water with a fuel such as alcohol or natural gas, or reforming the fuel with water. That is, as a basic principle of a fuel cell, hydrogen is generated from fuel and water supplied to the fuel electrode side of each cell usually arranged in a plurality of layers in the fuel cell, and hydrogen ions (protons) are converted into air through the electrolyte. An oxidation reaction with oxygen which is transferred to the electrode side and supplied to the air electrode side is performed, and an electromotive force is generated between the fuel electrode and the air electrode due to the reaction through this electrolyte. I have.

[0003] Fuel cells are generally classified into several types such as a phosphate type, a molten carbonate type, a solid oxide type, and a solid polymer type, depending on the type of electrolyte used. In recent years, research on solid electrolytes has been progressing, and the commercialization of more miniaturized fuel cells is expected. As a result of the miniaturization of the fuel cell, the fuel cell can be mounted on a vehicle, for example, as a power source of an electric vehicle, used as a portable power source for transportation, or used as a home power source.

[0004] In a power generation system using a fuel cell, the operating temperature of the fuel cell becomes considerably high (for example, as high as about 1000 ° C).
It is necessary to cool the fuel cell to a predetermined temperature or lower with cooling water.

[0005] In a large-scale power generation system using a fixed-installation type fuel cell, although there are some specific proposals for a cooling water system, a small-sized fuel cell mounted especially on a mobile body (for example, a fuel cell mounted on a vehicle) Battery)
This technology is expected to be developed in the future, and there are few proposals for specific structures.

[0006]

SUMMARY OF THE INVENTION The present invention proposes a novel structure especially for a cooling water system of a fuel cell mounted on a moving body. That is, the present invention provides a technology capable of solving various problems that occur or are expected to occur when the fuel cell power generation system is mounted on a moving body, and in particular, provide a novel technology for the cooling water system. .

In completing the present invention, consideration has been given to problems that occur in the cooling water system when the fuel cell power generation system is mounted on a moving body, or problems that are expected to occur.

First, in the fixed installation type fuel cell, it is possible to supply new cooling water as needed or to sequentially discharge old cooling water and replace it with new cooling water. However, when a fuel cell is mounted on a moving body, the water for cooling the fuel cell basically needs to be circulated and used, and it is necessary to constitute a cooling water circulation system with a cooler or a cooling mechanism.

In such a cooling water circulation system, the cooling water that has cooled the high-temperature fuel cell is cooled to a predetermined temperature by a suitable cooler or the like, and then is again used for cooling the fuel cell. The water will be recycled for a long time.

However, when the cooling water is circulated for a long period of time, for example, ions eluted from the casing of the fuel cell and substances eluted from various hoses, pipes, valves and the like existing in the cooling water circulation system are cooled. When mixed into water, the concentration of these impurities gradually increases during use. If the concentration of impurities increases, not only does the cooling efficiency decrease, but in some cases, the pipes may be clogged or corroded. Therefore, impurities in the cooling water must be removed as much as possible.

As an apparatus for removing such impurities,
Generally, an ion exchange device filled with an ion exchange resin is known. However, there is no example in which the ion exchange device is used in a cooling water system of a fuel cell power generation system mounted on a moving body. Further, in a generally known ion exchange apparatus, the entire amount of the water to be treated passing therethrough is treated, but if the ion exchange apparatus is used in the cooling water circulation system of the fuel cell as described above, In this case, it is conceivable that the entire amount of the circulated cooling water does not have to be treated each time. In other words, if part of the circulating cooling water is treated constantly,
It is possible to keep the amount of impurities in the cooling water of the entire cooling water circulation system below a certain level, and it is therefore likely that it will be considered sufficient. It is considered that the partial treatment instead of the treatment with the entire flow of water is a practically effective method because the size of the ion exchange device can be reduced and the life of the charged ion exchange resin can be extended.

The ion exchange resin filled in the ion exchange device reaches its life sooner or later and needs to be regenerated or replaced. However, when the fuel cell power generation system is mounted on a mobile body, the ion exchange resin is not used. Since it is impractical to mount up to the regenerating device, the exchangeability of the ion exchange device, more specifically, the detachability, must always be considered.

Further, when considering mounting on a moving body, especially an automobile, it is conceivable to mount it in an engine room where space is not enough. In this case, the workability of attaching and detaching the ion exchange device is taken into consideration. There is a need to.

It is an object of the present invention to provide a novel fuel cell cooling water circulating apparatus which is optimal when a fuel cell power generation system is mounted on a moving body, and to solve various problems conceivable in that case. It is an object of the present invention to provide a cooling water circulating device for a fuel cell which can satisfy the above-mentioned demand.

[0015]

In order to solve the above problems, a cooling water circulating apparatus for a fuel cell according to the present invention comprises a cartridge type ion exchanger which is detachably attached to a cooling water circulating line of a fuel cell mounted on a moving body. Is provided.

The moving body is typically an automobile, but other vehicles and hulls, as well as a portable power supply and the like are also possible.

As described above, it is not necessary to treat the entire amount of the circulating cooling water every time, and it is considered that the concentration of impurities in the entire cooling water system may be suppressed to a predetermined level or less. A configuration having a desalination line provided with a cartridge type ion exchanger and a bypass line bypassing the desalination line can be adopted.

The cartridge type ion exchanger can be installed horizontally or vertically. When the cartridge type ion exchanger is installed horizontally, it is preferable that the cartridge type ion exchanger has an inlet and an outlet for cooling water at both ends thereof, thereby facilitating attachment and detachment. When the cartridge-type ion exchanger is installed vertically, it is preferable that the cartridge-type ion exchanger has an inlet and an outlet for cooling water on the lower surface side, thereby facilitating attachment and detachment.

Further, in the cartridge type ion exchanger,
Preferably, an air vent is provided. If this air vent is connected to the downstream of the cartridge type ion exchanger in the cooling water circulation line, the air is smoothly discharged into the downstream cooling water which does not cause any inconvenience.

In the circulating cooling water line, it is necessary to provide a cooler at any part thereof to cool the circulating cooling water to a predetermined temperature. Considering the heat resistance of the ion exchange resin filled in the cartridge type ion exchanger, it is preferable that this cooler is provided upstream of the cartridge type ion exchanger in the cooling water circulation line. Also,
It is also possible to install the above-mentioned cooler upstream of the cartridge type ion exchanger in the desalination line, or to further provide another cooler different from the above.

The cartridge type ion exchanger is filled with an ion exchange resin. The tree of the ion exchange resin may be appropriately determined according to the type of impurities to be removed. For example, ion exchange resins are anion exchange resins,
What is necessary is just to consist of at least 1 type of cation exchange resin and those mixed resin. Further, the ion-exchange resin to be filled may be arranged in a plurality of layers, and may be a mixed-bed configuration of a plurality of types of ion-exchange resins.

The internal structure of the cartridge type ion exchanger can take various forms.

For example, a structure in which a filter is provided at least on the upstream side of the ion exchange resin in the cartridge type ion exchanger, or a structure in which a filter is provided on the downstream side can be adopted. The filter is made of a porous material or the like.

The ion exchange resin may be housed in a bag made of a cloth having water permeability. Also, a configuration in which a rectifying plate is provided in a cartridge type ion exchanger, a configuration in which a meandering passage of cooling water is formed in an ion exchange resin filling portion in the cartridge type ion exchanger, a cartridge type ion exchanger Within
A configuration in which a pressing means for pressing the charged ion exchange resin in the axial direction of the ion exchanger is provided.In the cartridge type ion exchanger, the charged ion exchange resin is placed radially inward of the ion exchanger. And a configuration in which a plurality of baffle plates extending in a comb shape toward the charged ion exchange resin are provided in the cartridge type ion exchanger.

Further, the cartridge type ion exchanger is
It is also possible to comprise an ion exchanger integrated with a cooling mechanism. The integrated cooling mechanism can be provided on the outer periphery of the ion exchanger, and can be provided on the upstream side of the ion exchange resin in the cartridge type ion exchanger.

In the cooling water circulating apparatus for a fuel cell according to the present invention as described above, since a removable cartridge type ion exchanger is provided in the cooling water circulating line, the circulating cooling water is removed by the cartridge type ion exchanger. The salt treatment removes ions as impurities in the cooling water, and when the filled ion exchange resin reaches the end of its life, it is replaced together with the cartridge type ion exchanger, and in some cases, only the ion exchange resin is replaced. After the replacement, the circulation of the necessary cooling water is continued. Since the cartridge-type ion exchanger is detachable, the exchange is very easy.

Further, if a cartridge type ion exchanger is provided in the desalination line, part of the cooling water which is diverted and passed through the desalination line is treated, and the rest is passed through the bypass line. As a result, while maintaining the impurity concentration of the cooling water as a whole below a predetermined level, the amount of water flowing to the ion exchange resin filled in the cartridge type ion exchanger can be suppressed small, and the life thereof can be greatly extended. The replacement frequency of the cartridge type ion exchanger can be reduced.

Further, as shown in the specific embodiments described later, by optimizing the installation posture of the cartridge type ion exchanger, the position of the entrance / exit, the air release and the internal structure, etc. Even in an installation place with a small extra space as described above, it is possible to ensure good detachability, exchangeability, performance of the ion exchanger itself, and the like.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a cooling water circulation device for a fuel cell according to one embodiment of the present invention, and 1 shows a fuel cell, particularly a housing thereof. Cooling water is circulated through the cooling water circulation line 2 in the fuel cell 1 to cool the inside of the casing. The fuel cell 1 and the cooling water circulation line 2 are mounted on a moving body, in this embodiment, in an engine room of an automobile.

The cooling water circulation line 2 is provided with a main cooler 3 for controlling the temperature of the heat generating portion of the fuel cell 1 to, for example, 1%.
When the temperature is about 000 ° C., the main cooler 3
The circulated cooling water is preferably cooled to, for example, about 125 ° C. As the main cooler 3, a dedicated cooler may be installed, but a radiator mounted on an automobile can also be used.

The cooling water from the main cooler 3 is supplied to a circulation pump 4
Is sucked and pumped. In the present embodiment, on the downstream side of the circulation pump 4, the cooling water circulation line 2 is connected to the desalination line 5.
And a bypass line 6 that bypasses the desalination line 5, and the desalination line 5 and the bypass line 6 join again on the downstream side. The flow ratio of the cooling water divided into the desalination line 5 and the bypass line 6 is, for example, 1:
It is set to about 3 to 1:30. It is not necessary to strictly set the flow rate ratio, and it is sufficient that the circulated cooling water partially flows through the desalination line 5. Therefore, the setting of the flow rate ratio is maintained at the initial mechanical design by utilizing the pressure loss difference in the cooling water circulation device itself between the relatively large pressure loss in the desalination line 5 and the small pressure loss in the bypass line 6. It is possible to do it all the time. Alternatively, it is also possible to provide a throttle or a flow control valve at the branch between the desalination line 5 and the bypass line 6 so as to allocate the water with higher accuracy.

The desalting line 5 is provided with a removable cartridge type ion exchanger 7. The cartridge type ion exchanger 7 is filled with an ion exchange resin, and desalinates the cooling water that is passed through. The ion exchange resin to be filled can be composed of at least one of an anion exchange resin, a cation exchange resin, and a mixed resin thereof. The ion exchange resin is a mixed bed in which a plurality of layers, particularly, a plurality of different resin layers are arranged. It can also be filled as a formula. In this embodiment, the cartridge type ion exchanger 7 is installed horizontally, and has an inlet 7a and an outlet 7b at both ends thereof.

In this embodiment, the cooling water passed through the desalination line 5 is cooled before flowing into the cartridge type ion exchanger 7 on the upstream side of the cartridge type ion exchanger 7 in the desalination line 5. A sub-cooler 8 is provided. This subcooler 8 can be omitted when the ion exchange resin filled in the cartridge type ion exchanger 7 has high heat resistance. Due to the cooling by the subcooler 8, the temperature of the cooling water flowing into the cartridge type ion exchanger 7 is sufficiently low (for example, 6 ° C.) in view of the heat resistance of the ion exchange resin filled.
0 ° C. or less).

As shown in FIG. 2, for example, as shown in FIG.
Is preferably provided. The air vent 9 may be provided on the upper wall of the horizontally disposed cartridge type ion exchanger 7, that is, above the charged ion exchange resin 10, and within the cartridge type ion exchanger 7 above the ion exchange resin 10. The air that has gathered in the air is vented through the air vent 9. The air vent 9 is communicated with the cooling water circulation line 2 downstream of the cartridge type ion exchanger 7 via a pipe 11, and the vented air is released into the cooling water circulation line 2. The connection destination of the pipe 11 may be any of a position in the desalination line 5 and a position after the desalination line 5 and the bypass line 6 are joined. Further, the air vent pipe may be built in the ion exchanger.

Inlet 7a of cartridge type ion exchanger 7
The side, the outlet 7b side, and the air vent 9 side are connected to each pipe by detachable means. As the detachable means, besides a simple mating flange structure, a substantially one-touch known joint mechanism can be adopted.

In the cooling water circulating apparatus for a fuel cell according to the present embodiment, the fuel cell 1 is cooled to a desired temperature by the cooling water circulated through the cooling water circulating line 2. Since the device is mounted on a moving object and the cooling water is circulated and used without substantial replacement,
In the circulating cooling water, elutes from the casing of the fuel cell 1 and the piping of the circulating system are mixed as impurities, and the concentration tends to gradually increase.

However, since the cartridge type ion exchanger 7 is provided in the desalination line 5 of the cooling water circulation line 2, the circulating cooling water is continuously desalted.
Impurities in the cooling water are removed. The cooling water circulated is
Although the water is diverted into the desalination line 5 and the bypass line 6 and actually subjected to the desalination treatment only in the desalination line 5, the cooling water used for cooling the fuel cell 1 requires less severe control of impurities. Since it is unnecessary, even in the case of partial desalination of cooling water, the circulated cooling water as a whole is maintained at a sufficiently low impurity concentration. As a result, the desired good cooling performance of the fuel cell 1 is ensured, and at the same time, problems such as blockage of the cooling water circulation line 2 and accumulation of impurities in the piping are prevented.

Further, since the cartridge type ion exchanger 7 is provided in the desalination line 5, only a part of the total amount of the circulating cooling water is desalted continuously.
Ion exchange resin 10 in cartridge type ion exchanger 7
Can be appropriately extended, and the frequency of replacement of the cartridge ion exchanger 7 can be reduced.

Furthermore, since the ion exchanger 7 is of a cartridge type and is configured to be detachable, the exchange can be performed very easily. In particular, in this embodiment, the cartridge-type ion exchanger 7 is installed horizontally, and has an inlet 7a and an outlet 7b at both ends thereof. It is possible to easily perform the attachment / detachment work at the inlet 7a, the outlet 7b, and the air vent 9 without being hindered by the above.

The internal structure of the cartridge type ion exchanger 7 can be configured in various modes.

For example, in the embodiment shown in FIG. 3, filters 22a and 22b made of, for example, a porous material are provided on the inlet side and the outlet side inside the cartridge type ion exchanger 21. The exchange resin 23 is disposed in a state of being housed in a bag 24 formed of a cloth having water permeability. It is preferable that the cloth having water permeability further has elasticity, and for example, a bag body 24 formed of stretch yarn is preferable.

In such a configuration, the ion-exchange resin 23 is held in the form by the bag 24, and the cooling water passed through can be more reliably subjected to desalination by the ion-exchange resin 23. Also, when the volume of the filled ion exchange resin 23 changes as a whole,
The entire amount of the ion-exchange resin 23 can be appropriately held by the bag 24.

In the embodiment shown in FIG. 4, filters 32a and 32b are provided in the cartridge type ion exchanger 31, and rectifying plates 34a, 34b and 34c are provided in the filling portion of the ion exchange resin 33 therebetween. Have been. Each of the straightening plates 34a, 34b, 34c is, for example, as shown in FIG.
As shown in (1), a large number of through-holes 35 are formed in the filling portion of the ion-exchange resin 33 on the lower side, and the upper end 36 side is blind.

In such a configuration, the flow of the cooling water in the cartridge type ion exchanger 31 is appropriately rectified, and the cooling water flows stably in the ion exchange resin 33 and contacts the ion exchange resin 33. The area is secured sufficiently wide. Further, by employing the arrangement structure of the through holes 35 as shown in FIG. 5, it is possible to appropriately supply the cooling water only to the filling portion of the ion exchange resin 33, and to change the volume of the ion exchange resin 33 during use. Can be appropriately dealt with.

In the embodiment shown in FIG. 6, filters 42a, 4a,
2b and the ion exchange resin 4
3 are provided with partial partitions 44a to 44e extending alternately from both upper and lower sides, and the partial partitions 44a to 44e are provided.
Thus, a meandering passage 45 of the cooling water is formed.

In such a configuration, the chance of contact between the flowing cooling water and the charged ion exchange resin 43 is greatly increased, and the efficiency of desalination treatment can be improved.

In the embodiment shown in FIG. 7, filters 52a and 52b are provided in a cartridge type ion exchanger 51, and an ion exchange resin 53 is filled between them. Then, the perforated plate 54 and the perforated plate 54 are urged toward the filter 52a on the side of the one filter 52a (that is, the cartridge type ion exchanger 5).
A spring 55 is provided.

In such a configuration, even if the ion exchange resin 53 undergoes a volume change (especially shrinkage) during use, the filter 52a is pressed by the axial pressing means including the spring 55 and the porous plate 54. Through ion exchange resin 5
3 is pressed so as to be compressed in the axial direction, so that the proper filling state of the ion exchange resin 53 is maintained, and the occurrence of an inappropriate short path of cooling water is prevented. Therefore, stable desalination treatment is continued.

In the embodiment shown in FIG. 8, filters 62a and 62b are provided in the cartridge type ion exchanger 61, and a flexible gas as shown in FIG. Are arranged horizontally, and an ion exchange resin 64 is provided inside the cylinder 63.
Is filled. The pressure of the pressurized gas to be sealed may be about 2 kg / cm ² .

In such a configuration, the form of the ion-exchange resin 64 is maintained by the flexible cylinder 63, and even when the ion-exchange resin 64 changes in volume, the cylinder 63 is filled with the sealed gas. Since the pressure appropriately presses the ion exchange resin 64 inward in the radial direction, the shape of the ion exchange resin 64 is maintained in an appropriate shape.
Therefore, stable desalination treatment is continued.

Further, in the embodiment shown in FIG. 10, filters 72a and 72
b, and ion exchange resin 73
Is filled. In particular, a plurality of comb-shaped baffles 74 extending downward from the upper wall in the cartridge-type ion exchanger 71 toward the filling portion of the ion-exchange resin 73 are provided between the filters 72a and 72b and the baffle 74. Further, spaces that do not communicate with each other are formed between the baffle plates 74.

In such a configuration, the baffle 74 prevents water from short-circuiting over the charged ion exchange resin 73, and the air inside the cartridge type ion exchanger 71 A space for air removal or air storage is appropriately formed, and stable desalination treatment can be performed.

In each of the above embodiments, the example in which the cartridge type ion exchanger is arranged horizontally is shown. However, in the present invention, the cartridge type ion exchanger can be installed vertically. However, also in this case, it is necessary to ensure easy attachment and detachment.

For example, it can be configured as shown in FIG. In FIG. 11, reference numeral 81 denotes a cartridge type ion exchanger installed vertically, and an ion exchange resin 83 is filled on a porous plate 82 provided inside. On the lower surface side of the cartridge type ion exchanger 81, an inlet 84 and an outlet 85 of the cooling water are provided, and the cooling water introduced from the inlet 84 is sent upward through the introduction pipe 86,
Cooling water supplied to the ion exchange resin 83 from a distributor 87 having, for example, a slit-shaped opening provided at the tip thereof and desalinated in the ion exchange resin 83 is discharged from the outlet 85 through the perforated plate 82. It has become. An air vent 88 is provided on the upper wall of the cartridge type ion exchanger 81.

The above cartridge type ion exchanger 81 comprises:
For example, as shown in FIG. 12, it is installed vertically in the desalination line 5 described above. Cartridge type ion exchanger 81
Attach 84 parts of inlet, 85 parts of outlet, air bleed 88
In the part, it may be performed via a mating flange or a one-touch joint. The pipe 89 from the air vent 88 may be connected to the downstream side of the cooling water circulation line.

In such a configuration, the cartridge-type ion exchanger 81 is installed vertically,
For example, a cartridge type ion exchanger 81 is attached to or detached from the desalination line 5 from above, and an inlet 84 and an outlet 85 arranged on the lower surface thereof can be easily attached to and detached from a predetermined joint of the desalination line 5. Therefore, the cartridge type ion exchanger 81 can be easily mounted or replaced even in an engine room or the like where there is little extra space, with the hood open.

Further, in the present invention, particularly when the heat resistance of the ion exchange resin to be filled is relatively low, or when the cooling water cannot be sufficiently cooled before reaching the inlet of the cartridge type ion exchanger. It is also possible to configure the cartridge type ion exchanger as an ion exchanger integrated with a cooling mechanism.

For example, as shown in FIG. 13, a cartridge type ion exchanger 91 is provided with filters 92a, 9a inside.
2b, between which an ion exchanger 94 filled with an ion exchange resin 93 is formed around a cooling water jacket structure 95, through which dedicated cooling water separate from the circulating cooling water flows. A configuration provided with a cooling mechanism can be employed.

Alternatively, as shown in FIG. 14, the inside of the cartridge type ion exchanger 101 is divided into an upstream cooling mechanism section 102 and a downstream ion exchange resin filling section 103 in the circulating cooling water flow direction, and the cooling section is cooled. The mechanism unit 102 is configured as, for example, a meandering cooling jacket unit 104, and a porous filter 105 is provided therein, and the porous filter 1 is provided.
In addition to cooling the circulating cooling water passing through the inside of the fuel cell 05, the ion-exchange resin filling unit 103 is filled with the ion-exchange resin 106, and a filter 107 is disposed downstream of the ion-exchange resin filling unit 103, and the cooling through the ion-exchange resin 106 is performed. It can be configured to desalinate water. Since the cooling water sufficiently cooled by the cooling mechanism 102 is subjected to the desalination treatment, the problem regarding the heat resistance of the ion exchange resin 106 is solved.

As described above, the structure of the cartridge type ion exchanger itself can take various forms. As long as the cartridge-type ion exchanger is detachable, it can be easily replaced on the moving body.
