Abstract
A resin-framed membrane electrode assembly for a fuel cell includes a stepped membrane electrode assembly and a resin frame member. The stepped membrane electrode assembly includes a solid polymer electrolyte membrane, an anode electrode, and a cathode electrode. The resin frame member surrounds an outer periphery of the solid polymer electrolyte membrane and includes an inner protruding portion that protrudes from an inner peripheral base portion toward the cathode electrode and that has a thickness. The inner protruding portion has an adhesive application portion to which an adhesive is applied so as to surround a part of the inner protruding portion. The part is in contact with the stepped membrane electrode assembly. A thickness of a cathode diffusion layer is larger than a thickness of an anode diffusion layer.
