５を介して外部の熱交換器６に接続さｎている。Since fuel cells generate heat through reactions, it is necessary to extract this heat to the outside, and for this reason a cooling device as shown in Figures 1A and 2 is provided. In these figures, l is a unit cell consisting of an air electrode, a fuel electrode, and an electrolyte interposed between them. A manifold 2 for supplying or discharging (air, oxygen, etc.) is provided. In addition, a cooler cell 3 is inserted for every appropriate number of unit batteries 1, and each cooling pipe 4 arranged in the groove of the cooler cell 3 is connected to a cooling main pipe 5 arranged in the manifold 2. It is connected to an external heat exchanger 6 via this cooling main pipe 5.

う欠点があった。However, in such a conventional cooling system, since there is only one cooling system consisting of the cooling main pipe 5 and the cooling pipe 4, the reliability against failure of the cooling system is low, and at low load,
That is, it is difficult to efficiently control the refrigerant flow rate across all layers of cells when the amount of heat generated is small. -Also, since all the cooling pipes 4 are drawn out into one manifold 2 and connected to the cooling main pipes 5 there, the intervals between the cooling main pipes 5 are narrowed, as shown in FIG. The disadvantage is that not only the flow of fuel or oxidant gas 7 that is supplied or discharged through the manifold 2 is disturbed by the cooling bus pipe 5, but also the workability of connecting the cooling pipe 4 and the cooling bus pipe 5 is poor. was there.

信頼性の高い燃料電池を提供することにある。An object of the present invention is to overcome the drawbacks of the prior art described above, to control the flow rate of refrigerant at low loads, to supply and discharge fuel or oxidizing gas, and to
Another object of the present invention is to provide a highly reliable fuel cell in which connection work between a cold maple pipe and a cooling main pipe can be performed satisfactorily.

たこと全特徴とする。In order to achieve this object, the present invention divides a cooling system consisting of a cooling bus pipe and a cooling pipe into at least two parts, and all of the cooling bus pipes of each cooling system are divided and arranged in separate manifolds. As a result, the space between each cooling main pipe is narrowed.
以下、本発明の一実施例を第３図および第４図について
説明する。なおこれら図中、第１図および第２図と同一
符号は同一物または相当物を示す。An embodiment of the present invention will be described below with reference to FIGS. 3 and 4. In these figures, the same reference numerals as in FIGS. 1 and 2 indicate the same or equivalent parts.
この実施例が前記した従来例と異なる点は、冷却母管お

ており、第１．第２の冷却系統の各冷却母管５Ａ、５Ｂ
が互に対向する側面を覆うマニホールド２内に分割して
配置され、かつ第１．第２の冷却系統の冷却管４Ａ。The difference between this embodiment and the conventional example described above is that the cooling system consisting of a cooling bus tube and a cooling tube is different from the first cooling system consisting of a cooling bus tube 5A and a cooling tube 4A, and a first cooling system consisting of a cooling bus tube 5B and a cooling tube 4B. The second cooling system is divided into two parts, the first and second cooling systems. Each cooling bus pipe 5A, 5B of the second cooling system
are arranged separately in the manifold 2 covering mutually opposing sides, and the first . Cooling pipe 4A of the second cooling system.
４Ｂが同一クーラーセル３上において交互に配置さｎて
いることである。図中、８は冷却系統を循環する冷媒で
ある。4B are arranged alternately on the same cooler cell 3. In the figure, 8 is a refrigerant that circulates in the cooling system.

の冷却母管５Ａ。Therefore, according to this embodiment, even if one cooling system fails, the other cooling system can provide cooling, and it is possible to prevent the battery from becoming abnormally high temperature. Moreover, the cooling main pipe 5A is located on both sides of the cooling pipes 4A and 4B located on the same cooler cell 3.
５Ｂより冷媒を供給するようになっているため、１つの

Ａ。Since the refrigerant is supplied from the cooling bus tubes 5B, the flow rate of the refrigerant flowing through each cooling bus tube 5A, 5B may be small, and the pipe diameter of the cooling bus tubes 5A, 5B can be made smaller than before. As a result, the space between each cooling bus tube 5A, 5B can be widened, so that the flow n of the fuel or oxidizing gas 7 is not obstructed by the cooling bus tubes 5A, 5B, and this nAk can be circulated well. At the same time, the cooling pipe 4

冷却系統のみで冷却することにより、負荷変動に応じて
効率よく冷却することができる。4B and the cooling bus pipes 5A and 5B become easier to connect. Furthermore, when the load is low, one cooling system is closed and cooling is performed only by the other cooling system, thereby allowing efficient cooling in response to load fluctuations.
第５図は本発明の他の実施例を示す。この実施例では、
第１．第２の冷却系統の冷却管４Ａ。FIG. 5 shows another embodiment of the invention. In this example,
1st. Cooling pipe 4A of the second cooling system.
４Ｂが互に異なりクーラーセル３上に配置されている。4B are different from each other and arranged on the cooler cell 3.
その他の構造は第３図および第４図の実施例と同じであ

４Ｂの管径は従来と同じであるが、両側のマニホールド
２内に分割して配置されるため、１つのマニホールド２
内に配置される冷却母管４Ａ、４Ｂの数が１／２に減少

信頼性を向上し、かつ低負荷時に効率よく冷却し得るこ
とも、前記実施例と同様である。The pipe diameter of 4B is the same as before, but it is divided into manifolds 2 on both sides, so one manifold 2
The number of cooling bus tubes 4A and 4B disposed within the cooling head tubes 4A and 4B is reduced to 1/2, and the interval between them can be widened. As a result, as in the embodiment described above, the flow of fuel or oxidant gas is improved, and the work of connecting the cooling pipe and the cooling main pipe becomes easy. Further, since the cooling system is a double system, reliability against failure is improved and cooling can be performed efficiently at low loads, as in the previous embodiment.
