Abstract
In a fuel cellincluding a membrane electrode assemblywhich includes a reinforcing-membrane-type electrolyte membraneA, a dry-up on the anode side is suppressed by actively forming a water content gradient in the electrolyte membrane to enhance water back-diffusion effect from the cathode side to the anode side. For that purpose, two sheets of expanded porous membranesandhaving different porosities are buried, as reinforcing membranes, in electrolyte resinto obtain the reinforcing-membrane-type electrolyte membraneA. The reinforcing-membrane-type electrolyte membraneA is used to form the membrane electrode assembly, which is sandwiched by separatorsandsuch that the side of a reinforcing membranewith a larger porosity becomes the cathode side, thus obtaining the fuel cell. When one sheet of the reinforcing membrane is buried, the reinforcing membrane is offset to the anode side to be buried in the electrolyte resin.
