摘要：
A seal member is formed integrally on surfaces of a metal separator of a fuel cell. The seal member includes an outer seal and an inner seal provided on a surface of the metal separator. A plurality of closure seals are formed integrally with an inner edge of the inner seal. The closure seals close a space between the inner seal and a protrusion forming a fuel gas flow field.
