Abstract
A power generating cell is equipped with an MEA to which a resin frame is attached, and a first metal separator. In the first metal separator, there are provided an oxygen-containing gas flow field through which an oxygen-containing gas flows along an electrode surface, an outer peripheral bead surrounding the oxygen-containing gas flow field and which prevents leakage of a reaction gas, and a plurality of first bypass stopping convex portions that prevent bypassing of the reaction gas. Intermediate convex portions that support the resin film are provided between mutually adjacent ones of the first bypass stopping convex portions.
