Claim:
1. A fuel cell system comprising: a fuel cell that generates power by an electrochemical reaction between hydrogen and oxygen contained in air; a compressor that supplies air to the fuel cell; and a controller that is programmed to wherein the controller is further programmed to detect a cell voltage or a cell group voltage, calculate the voltage condition on the basis of a result of the detection, determine as a calculation result determination, on the basis of a result of the calculation, whether a previous value of an air supply amount supplied intermittently to a cathode during the idle stop is excessive or insufficient, decide to reduce or increase the air supply amount relative to a preset fixed value or a previous supply amount in accordance with a result of the calculation result determination, and stop the air supply performed during the idle stop when the air supply amount reaches a predetermined value.
