Abstract: At shutdown of a fuel cell system, a system-shutdown controller is configured to cause a current extraction device to extract current from a fuel cell in a state where a supply of a fuel gas through a fuel supply system is continued and a supply of an oxidant gas through an oxidant supply system is stopped, and the system-shutdown controller is configured to airtightly close fresh-air control valves after increasing pressure of the fuel gas in a fuel electrode to not less than atmospheric pressure and not less than pressure of the oxidant gas in an oxidant electrode.
