摘要：
A fuel cell system has a fuel cell having a cathode and an anode; a device for supplying an oxidant gas to the cathode; a device for supplying a fuel gas to the anode; a device for controlling a pressure of the oxidant gas in accordance with an operation state of the fuel cell; a regulator to which a pressure of the oxidant gas is applied as a signal pressure via a signal pressure line, wherein the regulator regulates a pressure of the fuel gas based on the signal pressure; and a device for scavenging the signal pressure line by using a scavenging gas when or after electric power generation is stopped. A device for controlling the signal pressure may be provided in the signal pressure line. Preferably, the scavenging gas has a pressure and a temperature higher than those of the oxidant gas supplied to the cathode.
