摘要： In the method of the invention for producing an electrode-membrane-frame assembly, its principal part is formed by laying a first catalyst layer onto one of surfaces of an electrolyte membrane, arranging a first gas diffusion layer onto the surface of the first catalyst layer and inside the circumferential region of the electrolyte membrane, laying a second catalyst layer onto the other surface of the electrolyte membrane, and arranging a second gas diffusion layer onto the surface of the second catalyst layer and inside the circumferential region of the electrolyte membrane so as to make the position of the outer circumference of the second gas diffusion layer different from that of the outer circumference of the first gas diffusion layer. Then, in the state that an outer circumferential portion of either the first gas diffusion layer or the second gas diffusion layer, the portion being positioned outside a region of the first and second gas diffusion layers wherein the two layers are opposed to each other, is opposed to a portion of a flat region located inside the frame of a frame-form primary molded body, the circumferential region of the principal part is arranged on the flat region, and subsequently a secondary molded body is formed to cover the circumferential region of the electrolyte membrane with the second molded body together with the primary molded body, in order to prevent the polymer electrolyte membrane from being broken or deformed.

摘要： In an electrode-membrane-frame assembly production method, a principal part is formed by an electrolyte membrane, first and second catalyst layers and first and second gas diffusion layers, with the first and second gas diffusion layers arranged with their outer circumferences at different positions. The principal part is arranged in a molding die with a circumferential region of the principal part disposed on a flat region of a primary molded body. A circumferential portion of one of the gas diffusion layers is arranged to oppose a flat region of the primary molded body so that the membrane is interposed between the circumferential portion and the flat region. Subsequently, a secondary molded body is formed to integrate with the primary molded body and the principal part.

摘要： A close attachment region is provided on the outer side relative to an outer edge portion of a gas diffusion layer and on the inner side relative to the inner edge portion of a gasket as seen from the thickness direction of a polymer electrolyte membrane, such that separators and a frame member are closely attached to each other. Thus, it becomes possible to suppress an increase in the manufacturing cost and a reduction in the power generation performance, which is attributed to the impurity eluted from the gasket and flowing toward the gas diffusion layer.
