Abstract
A fuel cell separator includes a separator body configured to be arranged between membrane electrode assemblies and includes recesses and projections formed in the separator body. The projections include first projections that are configured to face an electrode layer of the membrane electrode assembly. A thin film is arranged on a surface of each of the first projections. The recesses include first recesses that open in a protruding direction of the first projections. Each of the first recesses is configured to form a passage through which oxidizing gas or fuel gas is supplied to the electrode layer. A portion of each of the thin films that is in contact with the electrode layer of the membrane electrode assembly includes a groove, the groove connecting to at least one of the passages located on opposite sides of one of the first projections that includes the thin film.
