<P>PROBLEM TO BE SOLVED: To provide a fuel cell making flow of reaction gas through a blocked clearance passage difficult and making the generation of a gap between a seal and a gas diffusion layer difficult, enhancing sealing effect, and effectively enhancing power generation efficiency when the clearance passage short-circuiting a manifold inlet and a manifold outlet is blocked with the seal. <P>SOLUTION: In the fuel cell comprising a polymer electrolyte membrane arranged between a pair of electrodes; the gas diffusion layers arranged on both sides of the polymer electrolyte membrane; a seal member installed integrally with the gas diffusion layer in the periphery of the gas diffusion layer; and a separator in which a reaction gas induction passage passing from the manifold inlet to the outlet is installed, a thin part is installed in the periphery of the gas diffusion layer and an elastic projection is installed on the both sides of the thin part. <P>COPYRIGHT: (C)2008,JPO&INPIT |
