Abstract
A processing method for a fuel cell system including a fuel cell stack configured to generate electric power when supplied with an anode gas and a cathode gas is started in a state in which the fuel cell stack is not supplied with the anode gas and the cathode gas and generation of electric power in the fuel cell stack is stopped. The processing method includes: a first process of starting supply of the cathode gas; a second process of starting supply of an inert gas to an anode when a voltage of the fuel cell stack increases and then becomes equal to or less than a predetermined first voltage; and a third process of stopping the supply of the inert gas when the voltage of the fuel cell stack increases and then becomes equal to or less than a predetermined second voltage after the second process.
