A fuel cell system includes: a low-frequency superimposition section superimposing a the low-frequency signal on a fuel cell; and an impedance computation section configured to compute low-frequency impedance of the fuel cell at a time when the low-frequency superimposition section superimposes the low-frequency signal on the fuel cell. The fuel cell system includes: a diagnosing section diagnosing a degree of dryness inside the fuel cell on the basis of low-frequency impedance; and an oxidant gas amount adjustment section configured to adjust an amount of oxidant gas in the fuel cell. The diagnosing section is configured to diagnose the degree of dryness inside the fuel cell on the basis of the low-frequency impedance when the oxidant gas amount adjustment section adjusts the amount of the oxidant gas to be equal to or smaller than a reference gas amount.
