Abstract:
1. A fuel cell, comprising: a plurality of overlaying single cells, each of which includes a reaction membrane including an electrolyte membrane and a catalyst layer disposed on each side of the electrolyte membrane, a pair of a gas diffusion layers disposed so as to envelop the reaction membrane, and a pair of a facing surfaces of a pair of separators disposed so as to envelop all of the former, wherein the pair of separators, at a location outward from a placement region for the reaction membrane, has respectively disposed a passage hole that forms a part of each of a manifold that passes through the overlaying direction of the single cells, wherein an elastic body is integrally disposed at a periphery of the pair of a gas diffusion layers, wherein the pair of separators each include a recessed section around a region that includes the passage hole, and formed a plurality of channels so as to pass through the recessed section and that form a flow route between the passage hole and the gas diffusion layer, and each separator of the pair of separators also possess passage holes that form a part of each manifold, and provides a plate member that is attached within the recessed section so as to cross over the plurality of channels, said plate member having a passage hole therein, and wherein the elastic body includes:
