    摘要: A fuel cell stack. A fuel cell stack, an example of the fuel cell stack, is configured by alternately overlaying first electricity generating units and second electricity generating units in the horizontal direction. The first electricity units are each provided with a first fuel gas flow path, a first oxidant gas flow path, a second fuel gas flow path, and a second oxidant gas flow path, and the flow paths are set to the same phase in the overlaying direction. The second electricity generating units are each provided with a first fuel gas flow path, a first oxidant gas flow path, a second fuel gas flow path, and a second oxidant gas flow path which are set to the same phase in the overlaying direction and are set to a phase different from the phase of the flow paths of the first electricity generating units.

    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: 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: A fuel cell is formed by stacking a membrane electrode assembly and separators alternately. Each of the separators includes first and second metal plates. A coolant flow field is formed between the first metal plate of the fuel cell and the second metal plate of the adjacent fuel cell. A folded section is provided around a coolant supply passage by folding the second metal plate. The folded section forms an inlet which enlarges the sectional area of an opening as a fluid passage between the coolant supply passage and the coolant flow field.
