description A fuel cell system is provided having at least one fuel cell including an oxidant electrode, a fuel electrode, and an electrolyte membrane interposed between the oxidant electrode and the fuel electrode. The fuel cell system includes a temperature detector which detects a temperature of the fuel cell and a controller which operates the fuel cell, controls a potential of the oxidant electrode, and determines whether to perform a performance recovery operation in which an impurity on the oxidant electrode is oxidized. When the performance recovery operation is to be performed, the controller controls the potential of the oxidant electrode to be a desired potential based on the temperature detected by the temperature detector.
