1. An inspection method of a fuel cell in which an electrolyte membrane is sandwiched between an anode-side electrode and a cathode-side electrode, comprising:

  • supplying a hydrogen gas to one of the anode-side electrode and the cathode-side electrode and supplying the hydrogen gas or an inert gas to the other electrode;

    applying a current from an external power supply to the one electrode and the other electrode so that the other electrode has a higher potential, and measuring a potential difference between the one electrode and the other electrode; and

    inspecting a performance of the fuel cell based on the potential difference between the one electrode and the other electrode measured when the current of a predetermined current value is applied from the external power supply to the one electrode and the other electrode, and an initial potential difference which is a potential difference between the one electrode and the other electrode before applying the current from the external power supply to the one electrode and the other electrode.
