Abstract
In a fuel supply device which supplies a fuel gas introduced from a fuel cartridge 3 to a fuel cell thorough a flow passage 40, the fuel supply device has: a fuel introduction valve 4 that introduces the fuel gas into the flow passage from the fuel cartridge; a purge valve 17 that discharges any gas other than the fuel gas introduced into the flow passage from the flow passage to effect gas replacement; and a fuel supply valve 19 that supplies the fuel gas introduced into the flow passage to a fuel cell main body, wherein the fuel gas is supplied to the fuel cell by controlling the fuel introduction valve 4, the purge valve 17, and the fuel supply valve 19 through at least one of mechanical operation and electrical operation performed from outside.
