Abstract:
In a power generation cell, first bypass stop protrusions for preventing bypassing of an oxygen-containing gas are provided between an end of an oxygen-containing gas flow field in a flow field width direction and an outer peripheral bead. An end wavy ridge includes curves recessed away from the outer peripheral bead. The first bypass stop protrusions are provided between the recessed curves and the outer peripheral bead. A first metal separator has first support protrusions for supporting a cathode, between the recessed curves and the first bypass stop protrusions.

Claim (Index 1):
A power generation cell comprising:\n a membrane electrode assembly formed by providing electrodes on both sides of an electrolyte membrane; and metal separators provided on both sides of the membrane electrode assembly, the power generation cell having a plurality of wavy ridges extending from one end to the other end of the metal separators, and a plurality of wavy flow grooves formed between the plurality of wavy ridges, wherein a reactant gas flow field is formed in the power generation cell, for allowing a reactant gas to flow from the one end to the other end of the metal separators along a power generation surface; a bead seal configured to prevent leakage of the reactant gas is provided around the reactant gas flow field; a bypass stop protrusion configured to prevent bypassing of the reactant gas is formed between an end of the reactant gas flow field in a flow field width direction and the bead seal; the bypass stop protrusion is provided between a recessed curve recessed away from the bead seal at the end of the wavy ridges in the flow field width direction, and the bead seal; and at least one of the metal separators includes a support protrusion configured to support the electrode, between the recessed curve and the bypass stop protrusion.
