    摘要： The present invention provides a membrane electrode assembly that enhances the reliability, mechanical strength, and handling characteristics of a seal in a solid polymer electrolyte fuel cell. The membrane electrode assembly of the present invention comprises a membrane-electrode structure having electrode layers and gas diffusion layers on both sides of a polymer electrolyte membrane, and a resin frame provided in such a manner as to fully enclose the outer periphery of the electrolyte membrane and to enclose at least portions of the outer peripheries of the gas diffusion layers, 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 the electrolyte membrane so that a surface region of the electrolyte membrane is left exposed. The gas diffusion layer on the opposite side extends all around the outer periphery of the electrolyte membrane. The resin frame is attached fixedly to at least a portion to the surface region.

    摘要： The durability of a solid polymer electrolyte fuel cell can be enhanced by inhibiting deterioration of a polymer electrolyte membrane of a solid polymer electrolyte fuel cell without impairing power generation performance. The production process of a polymer electrolyte membrane for a solid polymer electrolyte fuel cell of the present invention is characterized by preparing a solution or dispersion of an alkoxide of a transition element or a rare earth element having a catalytic ability that decomposes peroxides, and (1) preparing a solution of a polymer electrolyte, uniformly mixing the solution or dispersion of the alkoxide with the solution of the polymer electrolyte, and forming a polymer electrolyte membrane, in which the transition metal or the rare earth metal is uniformly dispersed, from the mixed solution, or (2) preparing a polymer electrolyte membrane for a solid polymer electrolyte fuel cell, uniformly permeating the solution or dispersion of the alkoxide into the polymer electrolyte membrane, and forming a polymer electrolyte membrane in which the transition element or rare earth element is uniformly dispersed by hydrolyzing and condensing the alkoxide.
