    摘要: A fuel cell includes a membrane electrode assembly and a metal separator. The metal separator is stacked with the membrane electrode assembly. A reactant gas passage is provided between the membrane electrode assembly and the metal separator to supply a reactant gas along an electrode surface. The metal separator includes a reactant gas communication hole to communicate with the reactant gas passage. The metal separator further includes a plurality of groove groups each having a plurality of grooves press-formed to allow the reactant gas communication hole to communicate with the reactant gas passage. The grooves adjacent to each other are spaced apart by a first distance. The groove groups adjacent to each other are spaced apart by a second distance larger than the first distance.

    摘要: A fuel cell includes a plurality of power generation cells each having a first separator. The separator has a fuel gas flow field. A fuel gas supply passage extends through one corner of the power generation cell in the stacking direction, a fuel gas flowing through the fuel gas supply passage into a fuel gas flow field. An inlet buffer is provided upstream of the fuel gas flow field. The fuel gas supply passage and the inlet buffer are connected by a plurality of inlet connection grooves. The inlet connection grooves are inclined from a direction perpendicular to a wall surface of the fuel gas supply passage toward the center of the fuel gas flow field.
