Zusammenfassung:	Here is disclosed a fuel cell system comprising: a fuel cell; a fuel gas system which supplies a fuel gas to the fuel cell and circulates the gas discharged from the fuel cell; a purge valve which discharges the gas from the fuel gas system; and control means for controlling the opening/closing operation of the purge valve. The control means controls the opening/closing operation of the purge valve so that impurities partial pressure in the fuel gas system is constant in the entire load region.
