Abstract

Provided is a method for inspecting a current leak of a fuel cell, which is provided with an anode electrode, a cathode electrode, and an electrolyte membrane sandwiched between the anode electrode and the cathode electrode, the method including: a first process in which a first voltage, which is a limit voltage of the electrolyte membrane, is applied to the fuel cell; a second process in which a second voltage, which is lower than the first voltage, is applied to the fuel cell after the first process; a third process in which a third voltage, which is lower than the second voltage, is applied to the fuel cell after the second process; and a determination process in which a value of a current flowing through the fuel cell in the third process is detected, and whether the detected current value is lower than a prescribed current value is determined.
