Abstract
A fuel cell system has a battery, a gas supply portion, a temperature acquisition portion configured to acquire a presumed temperature that is presumed to reach during the operation stop of the fuel cell; and a scavenging controlling portion. When it is determined that the presumed temperature is a predetermined temperature or more at the time of the operation stop of the fuel cell, the scavenging controlling portion performs the stop-time scavenging operation with a first scavenging ability; and when it is determined that the presumed temperature is less than the predetermined temperature, the scavenging controlling portion performs the stop-time scavenging operation with a second scavenging ability higher than the first scavenging ability.
