Abstract
A fuel cell joint separator includes a passage bead and an outer bead. In a dual seal section where the passage bead and the outer bead extend next to each other, a ridge protruding from one surface of a metal separator is formed integrally with the metal separator, between the passage bead and the outer bead. The height of the ridge is smaller than the height of the bead seal compressed by the tightening load. A joining line is provided between the outer bead and the ridge.
