1. A resin-framed membrane electrode assembly for a fuel cell, comprising:
a stepped membrane electrode assembly including
a solid polymer electrolyte membrane,an anode electrode disposed on one of surfaces of the solid polymer electrolyte membrane, the anode electrode including an anode catalyst layer and an anode diffusion layer, anda cathode electrode disposed on the other surface of the solid polymer electrolyte membrane, the cathode electrode including a cathode catalyst layer and a cathode diffusion layer, the cathode electrode having a size in plan view that is smaller than that of the anode electrode; and a resin frame member surrounding an outer periphery of the solid polymer electrolyte membrane and including an inner protruding portion that protrudes from an inner peripheral base portion toward the cathode electrode and that has a small thickness, the inner protruding portion being provided with an adhesive application portion formed from an adhesive that is applied so as to surround a part of the inner protruding portion, the part being in contact with the membrane electrode assembly, wherein a thickness of the cathode diffusion layer is larger than a thickness of the anode diffusion layer, and wherein the thickness of the inner protruding portion of the resin frame member is larger than the thickness of the cathode diffusion layer. |
