Abstract
A scavenging process is performed on the anode side by opening an air supply valve to remove liquid droplets in a fuel gas flow field using the compressed air from an air compressor. During the scavenging process, when a start up signal from an ignition switch is received, the start up of a fuel cell is prohibited until the gas in the fuel gas flow field is replaced completely by air.
