Abstract
A fuel cell separator (first and second separators) of a fuel cell stack is formed in a plate shape, and includes a passage bead (projection) configured to form a seal that prevents leakage of fluid. The passage bead is formed integrally with a surface of the separator in a manner so as to project from the surface, and when viewed in cross section, is formed in a multistage trapezoidal shape.
