摘要： A fuel cell stack includes a first power generation unit and a second power generation unit. Wave-like first fuel gas flow passages of the first power generation unit and wave-like first fuel gas flow passages of the second power generation unit are set to mutually different phases. The ends of the first fuel gas flow passages form linear flow passage grooves that linearly extend in the wavelength direction from the center of the width of the wave-form amplitude.

摘要： A fuel cell includes a membrane electrode assembly and a separator. The separator includes a water accumulation portion including at least one of a buffer portion, a lowermost channel groove, a channel junction portion, and a bypass channel. The buffer portion is connected to a reactant gas channel through which a reactant gas is to flow along a power generation surface of the membrane electrode assembly. The channel groove is provided in the reactant gas channel and located at a lowest position in the reactant gas channel in a direction of gravity when the membrane electrode assembly and the separator are in an upright position. Channel grooves of the reactant gas channel are joined in the channel junction portion. The membrane electrode assembly includes a water impermeable layer which is disposed outside of a power generation region and which faces the water accumulation portion.
