A fuel cell system characterized by including: a fuel cell (1) that generates electricity through electrochemical reactions between a hydrogen gas and an oxidizing gas; a hydrogen supply device (2) for supplying the hydrogen gas to the fuel cell; a hydrogen supply passage (21) through which the hydrogen gas supplied from the hydrogen supply device passes; an anode off-gas passage (22) through which an anode off-gas discharged from the anode side of the fuel cell passes; a hydrogen concentration sensor (3) provided on at least one of the hydrogen supply passage (21) and the anode off-gas passage (22); and a correction device (4) that reduces impurities in the passage provided with the hydrogen concentration sensor, measures hydrogen concentration using the hydrogen concentration sensor and corrects a reference point of the hydrogen concentration sensor based on the measured hydrogen concentration. |
