    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: A polymer electrolyte fuel cell is provided with a conductive separator having one or more gas flow channels for supplying and exhausting a gas to and from an electrode of the fuel cell. The gas flow channels are connected to and in fluid communication with an inlet manifold on the separator. The cell also includes a gas supply connection in fluid communication with the inlet manifold of the separator. Water accumulation in the cell can be advantageously reduced by configuring the connections to the inlet manifold so that the lowermost part of any gas flow channel connections with the inlet manifold is above the uppermost part of the gas supply connection to the inlet manifold.

    摘要: In a fuel cell composed of a pair of separators with a membrane electrode assembly sandwiched therebetween, gas passages having a plurality of generally linear passage portions, and bent passage portions each of which makes one end portion of the linear passage portions communicated with the other end portion of the linear passage portions, are formed so as to be communicative from a gas introducing port to a discharge port. In inner wall surfaces of the groove portions of the separators constituting the linear passage portions, water-retaining groove portions capable of retaining inside thereof at least part of water generated in the gas passage are formed in such a grooved configuration as to be substantially continuous along the passage portion. As a water drop generated within the gas passage makes contact with retained water within the water-retaining groove portions, growth of the water drop is suppressed to avoid any blockage of the gas passage, by which the anti-flooding property is improved.
