Abstract
A power generation cell includes a resin film equipped MEA and a first metal separator. The first metal separator includes an oxygen-containing gas flow field, an outer peripheral bead, and a first bypass stopping convex portion. An oxygen-containing gas flows across the oxygen-containing gas flow field along an electrode surface. The outer peripheral bead surrounds the oxygen-containing gas flow field to prevent leakage of a reactant gas. The first bypass stopping convex portion extends from the outer peripheral bead. A corner of a cathode on at least one end in the flow field direction of the oxygen-containing gas flow field is overlapped with an apex portion of the first bypass stopping convex portion.
