摘要： A polymer electrolyte fuel cell of the present invention includes a membrane-electrode assembly (5) and separators (6A, 6B). A plurality of reactant gas channels are formed on a main surface of at least one of the separator (6A, 6B) and a gas diffusion layer (3A, 3B). In a case where among the plurality of reactant gas channels, a reactant gas channel overlapping the peripheral portion of the electrode (4A, 4B) twice is defined as a first reactant gas channel, and a reactant gas channel formed to overlap the peripheral portion of the electrode (4A, 4B) and formed such that the length of a portion overlapping the peripheral portion is longer than a predetermined length is defined as a second reactant gas channel, the second reactant gas channel is formed such that the flow rate of a reactant gas flowing therethrough is lower than that of the reactant gas flowing through the first reactant gas channel or the second reactant gas channel does not exist.

摘要： A method for producing an electrode-membrane-frame assembly according to the present invention includes arranging a previously molded first molded body on a circumferential region of first catalyst layer close to first gas diffusion layer, arranging a previously molded second molded body on a circumferential region of second catalyst layer close to second gas diffusion layer, and forming a third molded body by injection molding so as to integrally connect the first molded body and the second molded body and not to be directly in contact with an inner side region of second main surface of a polymer electrolyte membrane positioned on an inner side of an outer edge part of the second molded body when viewed from a thickness direction of the polymer electrolyte membrane, whereby a frame having the first, second, and the third molded body is formed. Thus, the polymer electrolyte membrane can be prevented from deteriorating.
