摘要：The present invention provides a membrane electrode assembly that enhancesthe reliability, mechanical strength, and handling characteristics of a seal in a solidpolymer electrolyte fuel cell. The membrane electrode assembly of the presentinvention comprises a membrane-electrode structure having electrode layers and gasdiffusion layers on both sides of a polymer electrolyte membrane, and a resin frameprovided in such a manner as to fully enclose the outer periphery of the electrolytemembrane and to enclose at least portions of the outer peripheries of the gas diffusionlayers, the resin frame being provided so as to enclose the electrolyte membrane side.The gas diffusion layer and electrode layer on one side are stacked on a surface of theelectrolyte membrane so that a surface region of the electrolyte membrane is leftexposed. The gas diffusion layer on the opposite side extends all around the outerperiphery of the electrolyte membrane. The resin frame is attached fixedly to at least aportion to the surface region.
