    摘要: A power generation cell includes a membrane electrode assembly and first and second metal separators sandwiching the membrane electrode assembly. The first metal separator is a thin metal plate. A first seal member is formed integrally around the outer end of the first metal separator. A portion defining an orifice is provided in an outer marginal region of the first metal separator. The thickness H1 of the first seal member in the area covering the portion defining the orifice is larger than the thickness of the H2 of the first seal member in the area covering other portions.

    摘要: A power generation cell includes an anode side seal member and a cathode side seal member. The anode side seal member is provided outside an anode of a membrane electrode assembly, and directly contacts a solid polymer electrolyte membrane. The cathode side seal member is provided outside the membrane electrode assembly. A space is formed between the anode side seal member and the cathode side seal member. First ribs are formed integrally with the anode side seal member. The first ribs protrude toward the space. Further, second ribs are formed integrally with the cathode side seal member. The second ribs protrude toward the space. The first ribs and the second ribs are arranged alternately.

    摘要: An assembling operation of a fuel cell is effectively simplified. With the simple and economical structure, the desired sealing function is achieved. The fuel cell (10) includes a membrane electrode assembly (14) and first and second metal separators (16, 18) sandwiching the membrane electrode assembly (14). Connection channels (28a, 28b) are provided on the first metal separator (16). The connection channels (28a, 28b) connect the oxygen-containing gas supply passage (20a) and the oxygen-containing gas discharge passage (20b) to the oxygen-containing gas flow field (26). The membrane electrode assembly (14) has first overlapping portions (66a, 66b) overlapped on the connection channels (28a, 28b) for sealing the connection channels (28a, 28b). The first overlapping portions (66a, 66b) comprise, in effect, a gas diffusion layer.

    摘要: A fuel cell includes a membrane electrode assembly, and a first separator and a second separator sandwiching the membrane electrode assembly. The membrane electrode assembly has a resin frame member, and an inlet buffer is provided on the resin frame member adjacent to the fuel gas supply passage. The inlet buffer includes a first buffer area adjacent to the fuel gas supply passage and a second buffer area adjacent to a fuel gas flow field. The opening dimension of the first buffer area in a stacking direction is larger than the opening dimension of the second buffer area in the stacking direction.
