Abstract
A fuel cell system for a vehicle includes a fuel cell, a fuel supply device, an oxidizer supply device, an anode potential measuring device, and a discharge controller. The anode potential measuring device is configured to measure an anode potential of an anode. The discharge controller is configured to control discharge of electric current from the fuel cell as part of a process of stopping the fuel cell during idling of the vehicle. When receiving idle stop permission for the fuel cell, the discharge controller determines whether the fuel cell is permitted to discharge. When the anode potential is equal to or lower than a predetermined threshold value, the discharge controller permits the fuel cell to discharge. When the anode potential is higher than the predetermined threshold value, the discharge controller does not permit the fuel cell to discharge.
