Abstract
A seal member is formed integrally on surfaces of a metal separator of a fuel cell. The seal members include an outer seal provided near the outer edge of the separator, and an inner seal spaced inwardly from the outer seal by a predetermined distance. When a load is applied to the outer seal and the inner seal in a stacking direction, the outer seal and the inner seal are deformed substantially equally in the stacking direction to the same extent.
