    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.

    摘要: An oxygen-containing gas flow field for supplying an oxygen-containing gas from an oxygen-containing gas supply passage to an oxygen-containing gas discharge passage is formed on a first metal plate. The oxygen-containing gas flow field includes oxygen-containing gas flow grooves as serpentine flow grooves having two turn regions T1, T2. The oxygen-containing gas flow grooves have substantially the same length. The oxygen-containing gas flow grooves are connected to an inlet buffer and an outlet buffer at opposite ends. The inlet buffer and the outlet buffer have a substantially triangular shape, and are substantially symmetrical with each other.
