Abstract:
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.

Claim (Index 1):
A fuel cell system including a fuel cell that outputs electrical energy through an electrochemical reaction between fuel gas and oxidant gas, the fuel cell being a polymer electrolyte fuel cell, the fuel cell system comprising:\n a low-frequency superimposition section configured to superimpose a low-frequency signal on the fuel cell, the low-frequency signal being at a low frequency that is equal to or lower than a specified reference frequency; an impedance computation section configured to compute impedance of the fuel cell at a time when the low-frequency superimposition section superimposes the low-frequency signal on the fuel cell; a diagnosing section configured to diagnose a degree of dryness inside the fuel cell on the basis of the impedance computed by the impedance computation section; and an oxidant gas amount adjustment section configured to adjust an amount of the oxidant gas in the fuel cell, wherein\n the diagnosing section is configured to diagnose the degree of dryness inside the fuel cell on the basis of the impedance when the oxidant gas amount adjustment section adjusts the amount of the oxidant gas to be equal to or smaller than a specified reference gas amount.
