Zusammenfassung:	PURPOSE: A fuel cell system and a fuel supply method thereof are provided to improve the efficiency of a fuel cell system and to solve fuel supply problems by supplying fuel from the inside of the system. CONSTITUTION: A fuel cell system includes; a fuel tank(110); a fuel supply unit(120) supplying the first fuel to the fuel tank; a fuel cell stack(130) which supplies the second fuel to the fuel cell stack and generates the first gas; a liquefaction recycle unit(140) for liquefying the first gas to the recycled fluid; a liquid level modulation unit(150) which maintains a stable fuel level of the second fuel of the fuel tank by guiding the recycled fluid to the fuel tank; a sensing unit(160) of current signal provided by the fuel cell unit; and a control unit(170).
