The flow is diverted to carry out a cell reaction with the fuel gas of the counter electrode and cool the stack. The air that has taken heat from the stack to raise its temperature is
External discharge flow (15) and circulation flow (16) due to damper (14)
This circulating flow is sent to the stack again together with the fresh air flow (17) introduced from the outside in proportion to the external discharge amount. The partial discharge of the heated air and the introduction of fresh air compensate for the decrease in the temperature of the air supplied to the stack and the decrease in the oxygen partial pressure in the air.

価値はきわめて大きい。(G) Effect of the Invention According to the present invention, since the cross flow type fan is installed in the inlet side manifold of the battery stack, it is possible to reduce the space volume of the system by eliminating the need for piping between them. In addition, due to the characteristics of the cross flow type fan, the vertical distribution of the gas sucked into the manifold is made uniform, and the lateral distribution is of course uniform. Therefore, it is possible to provide a fuel cell equipped with a cooling gas supply device that has a selected function that also serves as a cooling gas or a reaction gas, such as the need for a conventional rectifying plate, and so its industrial value is extremely large.
