が増すという欠点があった。(0) Prior Art The operating temperature of a cynic acid fuel cell is appropriately around 180°C, but it rises to over 200°C due to the heat of cell reaction, so cooling is required. It is well known that air or hydrogen gas is used as a cooling gas, but although air is superior in safety, it has inferior heat capacity compared to hydrogen, which increases the number of circulating air fish and requires large-capacity blowers and heat recovery equipment. On the other hand, although hydrogen gas improves the above-mentioned drawbacks of air cooling, hydrogen gas is flammable and contamination with oxygen gas increases the danger. There were drawbacks.

Gradually accumulated 11
There is a risk of explosion if 12 and 02 are mixed together.

It is introduced into a regular circulation path (7) via an on-off valve (8).

This catalyst (9) is made by supporting precious metals such as platinum and palladium on carbon vapor or carbon fiber carbon steel wire mesh. When wrapped in a net or the like and fixed to the inner wall of the cooling hydrogen gas outlet side manifold (4), the embodiment shown in FIG. 5) The case where the internal space is filled is shown.

During long-term operation of the battery, these reactive gases gradually accumulate in the circulation path (7) during long-term operation of the battery. Of the reactant gases that accumulate, hydrogen gas is of the same quality as the cooling gas, so there is no problem, but the accumulation of air is extremely dangerous since 02 and H2 are present in the circulation path (7). However, since this 02 easily reacts with H2 to generate water in the presence of a catalyst (9) such as platinum, 02 does not accumulate in the circulation path (7). The amount of water produced after the reaction is small, and the battery temperature is 160"
Although it is water vapor because it is higher than C, there is no risk of interfering with the cooling ability of hydrogen gas.

た水素ガス冷却を安全に採用することができる。(g) Effects According to the present invention, since a catalyst is installed in the circulation path of hydrogen gas that cools the battery stack, the oxygen gas in the reaction air leaking from the battery stack into the circulation path is converted into hydrogen gas by the action of the catalyst. There is no risk that oxygen gas will be mixed and accumulated in the path, and the risk of explosion can be prevented. Therefore, hydrogen gas cooling, which is more efficient than air cooling, can be safely employed.
