Abstract
A fuel cell includes a membrane electrode assembly, a separator, a reactant gas channel, a reactant gas manifold, and a buffer portion. The buffer portion includes a first buffer region and a second buffer region. The second buffer region is located in a vicinity of the reactant gas manifold and is deeper than the first buffer region in a stacking direction. Embossed portion groups are arranged in a plurality of rows in the second buffer region between the reactant gas manifold and the first buffer region. Each of the embossed portion groups includes a plurality of embossed portions. A disposition density of the plurality of embossed portions of one of the embossed portion groups in a vicinity of the reactant gas manifold is lower than a disposition density of the plurality of embossed portions of another of the embossed portion groups in a vicinity of the first buffer region.
