Claim 1:
2. The fuel cell system according to claim 1, comprising:
a fuel supply part configured to supply the fuel to the anode channel; and
an oxidant supply part configured to supply the oxidant to the cathode channel,
wherein the control part executes electric power generation using the fuel and the oxidant remaining in the fuel cell 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 in a state in which supply of the fuel by the fuel supply part is executed while the anode opening/closing part is set to an open state and the cathode opening/closing part is set to a closed state.
