Abstract
A fuel cell system includes a fuel cell stack configured to supply power to an electric motor for driving a vehicle as well as generating power by an electrochemical reaction between a fuel gas and an oxidant gas, a discharge circuit and the discharge control circuit. The discharge circuit may form a plurality of discharge paths through which power generated in the fuel cell stack is discharged switching elements switching the connection relationships between resistance elements. The discharge control circuit form a second discharge path whose resistance value is smaller than the resistance value of the first discharge path and to switch the discharge through a first discharge path to discharge through the second discharge path when the detected voltage that is detected by the voltage detection unit is lower than a predetermined threshold voltage during the discharge through the first discharge path.
