A fuel cell system according to the present invention comprises a control apparatus which performs performance restoration processing for a catalyst layer by decreasing the output voltage of a fuel cell to a predetermined voltage. When an oxide film formed on the catalyst layer during power generation of the fuel cell contains, in addition to a first oxide film that can be removed by decreasing the output voltage of the fuel cell to a first oxide film removal voltage, a second oxide film that can be removed by decreasing the output voltage of the fuel cell to a second oxide film removal voltage which is lower than the first oxide film removal voltage, the control apparatus estimates the amount of the second oxide film and performs performance restoration processing with a set voltage being equal to or lower than the second oxide film removal voltage only when it determines that the estimated amount exceeds a predetermined amount A.
