<P>PROBLEM TO BE SOLVED: To suppress the stay of liquid water at the blocked downstream end of a first passage connected to a gas supply port. <P>SOLUTION: A gas passage is separated into: a first passage connected to a gas supply port at the upstream end and blocked at the downstream end; and a second passage blocked at the upstream end and connected to a gas exhaust port at the downstream end. A folded-back surface is formed in the blocking surface at the downstream end of the first passage so that the flow of a reaction gas of the first passage is folded back in an oblique direction from the blocking surface, and is directed in the gas diffusion layer direction. <P>COPYRIGHT: (C)2012,JPO&INPIT |
