Classification: CPC H  Y | IPC H

Claim 3:
4. The fuel cell system according to claim 3, comprising:
a fuel supply part configured to supply the fuel to the anode channels of the plurality of fuel cells; and
an oxidant supply part configured to supply the oxidant to the cathode channels of the plurality of fuel cells,
wherein the control part sets electric power generation execution and electric power generation stoppage of each of the plurality of fuel cells according to an output requirement,
the control part executes electric power generation using the fuel and the oxidant remaining in each of the plurality of fuel cells by stopping supply of the fuel by the fuel supply part and supply of the oxidant by the oxidant supply part, and then
the control part determines whether the cross leak is present on the basis of the pressure difference or the change in the pressure difference for each of the plurality of fuel cells in a state in which supply of the fuel by the fuel supply part is executed while simultaneously setting the plurality of anode opening/closing parts to an open state and the plurality of cathode opening/closing parts to a closed state.
