ABSTRACT:
A fuel cell system comprises a fuel cell, a supply flow passage for flowing a fuel gas supplied from a fuel supply source to the fuel cell, a variable gas supply device for regulating the state of the gas on the upstream side of the supply flow passage to supply the gas to the downstream side, a discharge flow passage for flowing a fuel off gas discharged from the fuel cell, a discharge valve for discharging the gas from the discharge flow passage to the exterior, and a control part for closing the discharge valve when the discharge amount of the gas calculated while the discharge valve is opened exceeds a predetermined target discharge amount. The control part stops the gas supply from the variable gas supply device and simultaneously closes the discharge valve, when the discharge amount of the gas calculated while the discharge valve is opened exceeds the target discharge amount.
