Abstract
A first outer peripheral seal in a first metal separator of a fuel cell stack includes a first peripheral metal bead. A first bypass stopper is provided in a space between a first end ridge and a first outer peripheral seal. The first bypass stopper prevents bypassing of an oxygen-containing gas by blocking part of the space. A gap is provided between the first bypass stopper and the first metal bead of a first outer peripheral seal. The gap separates the first bypass stopper from the first metal bead.
