Zusammenfassung:	According to the present invention, a fuel cell system for a submarine can supply hydrogen gas having a low carbon monoxide content as a raw material to a fuel cell while the hydrogen gas passes through a purification unit using a selective oxidation, thereby preventing deterioration of an electrode activity due to carbon monoxide. In addition, the fuel cell system for a submarine can be miniaturized and lightweight and the amount of exhaust gas can be simultaneously minimized since unreacted gas is burned in a fuel cell stack and recycled to supply heat to a reforming unit. 본 발명에 따른 잠수함용 연료전지 시스템은 수소 가스가 선택적 산화반응을 이용한 정제부를 거치면서 일산화탄소의 함량을 낮춘 수소 가스를 연료전지에 원료로 공급할 수 있어서, 일산화탄소에 의한 전극활성의 저하를 방지할 수 있다. 또한, 상기 잠수함용 연료전지 시스템은 소형화 및 경량화가 가능하면서 연료전지 스택에서 미반응된 가스를 연소시켜 개질부에 열을 공급하는데 재활용하므로 배출가스의 양이 최소화될 수 있다.
