摘要:
A fuel battery includes an oxidant gas flow passage having a downstream section, in which a gas diffusion porous body is arranged. The fuel battery includes a fuel gas flow passage having a downstream section, in which a gas diffusion porous body is arranged. A cooling medium flow passage is formed between a first separator of each unit cell of the fuel battery and a second separator of a unit cell adjacent to the unit cell. The flowing direction of a cooling medium in the cooling medium flow passage is the same as that of oxidant gas in the oxidant gas flow passage. An upstream section of the cooling medium flow passage is located closer to a surface of a membrane-electrode assembly that faces the oxidant gas flow passage adjacent to the cooling medium flow passage as compared with a downstream section of the cooling medium flow passage.
