Abstract
When a power generation stop signal of an ignition switch is detected, an oxygen-containing gas is supplied to an anode for starting an anode scavenging process. After starting the anode scavenging process, the remaining electrical energy stored in a capacitor is monitored. If the monitored remaining electrical energy stored in the capacitor is decreased to a threshold, the anode scavenging process is finished. At the end of the anode scavenging process, the remaining electrical energy becomes equal to the threshold. By the remaining electrical energy equal to the threshold, the next operation of the fuel cell system is reliably started. Since the anode scavenging process continues until the remaining electrical energy is decreased to the threshold, the time for the anode scavenging process can be increased as much as possible.
