    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 includes a membrane electrode assembly and first and second metal separators sandwiching the membrane electrode assembly. Connection channels are provided on the first metal separator. The connection channels connect the oxygen-containing gas supply passage and the oxygen-containing gas discharge passage to the oxygen-containing gas flow field. The membrane electrode assembly has first overlapping portions overlapped on the connection channels for sealing the connection channels. The first overlapping portions comprise, in effect, a gas diffusion layer.

    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 plurality of metal clip members for holding outer regions of first and second metal separators at a plurality of positions. Each of the metal clip member includes a side plate and first and second holding portions. The side plate is curved at opposite ends, and the first and second holding portions are extending from the opposite ends of the side plate. The first and second holding portions generates a predetermined elastic force for holding the first and second metal separators. The outer ends of the first and second metal separators are covered by insulating sections, and the insulating sections are held between the first and second holding portions so that the entire unit cell is tightened by the predetermined elastic force.
