FUEL CELL SYSTEM AND VEHICLE EQUIPPED WITH FUEL CELL

A fuel cell system used in a vehicle equipped with a fuel cell includes: a fuel cell (100); a fuel gas supply portion (220) which supplies a fuel gas to the fuel cell; a fuel gas discharge portion (230) which discharges exhaust fuel gas from the fuel cell; and a control unit (110), in which, when an operation of the fuel cell is ended, the control unit performs (a) an exhaust process of discharging the exhaust fuel gas of the fuel cell to reduce a pressure, and (b) a process of increasing a partial pressure of the fuel gas in the fuel cell by supplying the fuel gas to the fuel cell after the exhaust process.
