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 oxygen-containing gas supply ports or oxygen-containing gas discharge ports to change the flow direction of an oxygen-containing gas in an oxygen-containing gas flow field continuously.
