GAS FLOW PATH FORMING BODIES OF FUEL CELL, AND FUEL CELL

摘要

A plurality of gas flow passages (32, 132) and a plurality of water introducing passages (33, 133) are disposed on a gas flow passage forming body (31, 41) of a fuel cell (11). Linking passages (36, 136), which link adjacent gas flow passages (32, 132) and water introducing passages (33, 133) and through which water passes, are disposed between a gas flow passage (32, 132) adjacent to one of the water introducing passages (33, 133) and said one water introducing passage (33, 133). A facilitation part (39, 139), which facilitates the combining of water that is discharged from water discharge-side end sections of two water introducing passages (33, 133) that are adjacent to each other among the water introducing passages (33, 133), is disposed on the water discharge-side of the two water introducing passages (33, 133). Thus, the drainage performance of the water introducing passages (33, 133) of the gas flow passage forming body (31, 41) is improved, and water in the gas flow passages (32, 132) is reduced. As a result, the performance of the fuel cell improves due to an improvement in the diffusion of gas.
