Abstract
A fuel cell system () of the present invention includes a fuel cell stack () including plural single fuel cells () stacked on each other, each single fuel cell being supplied with hydrogen gas and air to an anode electrode () and a cathode electrode (), respectively, to generate electricity. The system () further includes a voltage applying device (C) that applies voltage to the fuel cell stack () after oxygen present in the cathode electrode () is reduced. The system () further includes a cross-leakage diagnosis device (C) that diagnoses, based on voltage of the single fuel cells () when the voltage applying device (C) applies the voltage to the fuel cell stack (), whether hydrogen gas in the anode electrode () is cross-leaked to the cathode electrode () in each single fuel cell ().
