    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 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 fuel cell includes a membrane electrode assembly and first and second metal plates sandwiching the membrane electrode assembly. The first metal plate has positioning ribs for positioning the outer region of the membrane electrode assembly. The first and second metal plates are positioned in alignment with each other by the first and second insulating bushings attached to first and second positioning holes of the first and second metal plates. Further, the first and second metal plates sandwiching the membrane electrode assembly are fastened together by a plurality of metal clip members.

    摘要: A cell unit of a fuel cell includes a first membrane electrode assembly, a first metal separator, a second membrane electrode assembly, and a second metal separator. A resin frame member is provided integrally with an outer circumference of the first membrane electrode assembly. An oxygen-containing gas supply passage, a fuel gas supply passage, a coolant supply passage, an oxygen-containing gas discharge passage, a fuel gas discharge passage, and a coolant discharge passage extend through the resin frame member in a stacking direction. At each of both ends of the resin frame member in a longitudinal direction, a pair of projections are provided. The projections protrude toward both sides in a lateral direction.

    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.
