Abstract

A fuel cell includes an electrolyte electrode assembly and a pair of first and second separators. First through fourth oxygen-containing gas holes, first through fourth coolant holes, and first through fourth fuel gas holes extend through the fuel cell. The first through fourth oxygen-containing gas holes are selectively used as an oxygen-containing gas supply port or an oxygen-containing gas discharge port to cause an oxygen-containing gas to flow circularly along an electrode surface in an oxygen-containing gas flow field.
