Abstract
A fuel cell system includes a fuel cell, an oxidant gas passage, a cathode off-gas passage, a fuel gas passage, a circulation passage, an anode off-gas passage, a fuel shutoff valve, a supply device, a humidifier and a control device. The supply device supplies a scavenging gas, which is for scavenging the fuel cell, to the anode and the cathode. The humidifier humidifies the scavenging gas. The control device controls the supply device when the fuel cell is turned off so that supply of the fuel gas to the anode is shut off and the scavenging gas is supplied to the anode and the cathode, wherein supply of the scavenging gas to the cathode is conducted through the humidifier.
