In a fuel cell, a plurality of supply gas passages (6a, 7a) and a plurality of discharge gas passages (6b, 7b) are formed in a separator. Communication between the supply gas passages and the discharge gas passages is not permitted. In the thus configured fuel cell, a member (2) of the separator, which forms portions between the gas passages is porous. Thus, water generated at electrodes (3, 4) can be absorbed in the porous members (2). It is therefore possible to suppress occurrence of blockage in the catalytic layer and the diffusion layer due to water existing at the electrodes (3, 4). Namely, flooding can be prevented. As a result, it is possible to increase an area in the fuel cell, where a reaction actually occurs, and therefore increase a power density of the fuel cell. |
