Abstract
A separator is stacked on each of both surfaces of a membrane electrode assembly to form a fuel cell. This separator includes a base part extending in the form of a surface, and a bead continuous with the base part and protruding from the base part in a stacking direction. The bead includes, in plan view, a straight section extending straight and a curved section continuous with the straight section and curved from the straight section. In the separator, the height from the base part to a top part of the curved section is configured to be lower than the height from the base part to a top part of the straight section.
