The present invention relates to a fuel cell system of an underwater moving body. According to an embodiment of the present invention, the fuel cell system includes: a fuel modifier configured to generate a modification gas including a large amount of hydrogen through modification of a fuel; a fuel cell configured to receive high-purity hydrogen obtained by purifying the modification gas generated by the fuel modifier and generate electric energy; a recirculation pipe connected between an exit side of the fuel cell and an entrance side of the fuel modifier; and a recirculation control valve configured to recirculate hydrogen that has not reacted yet from the fuel cell to the fuel modifier through the recirculation pipe. According to the present invention, the submersion performance of the underwater moving body can be improved by recirculating the hydrogen that has not reacted yet from the fuel cell to the fuel modifier and thus increasing the yield rate of hydrogen in the fuel modifier and the fuel efficiency of the fuel cell.
본 발명은 수중운동체의 연료전지시스템에 관한 것으로서, 본 발명의 일 실시예에 따르면 연료개질을 통해 다량의 수소를 포함하는 개질가스를 생성하는 연료개질기, 상기 연료개질기에서 생성된 개질가스로부터 정제된 고순도 수소를 공급받아 전기에너지를 생성하는 연료전지, 상기 연료전지의 출측과 상기 연료개질기의 입측 사이에 연결되는 재순환 배관, 및 상기 연료전지로부터 미반응된 수소를 상기 재순환 배관을 통해 상기 연료개질기로 재순환시키는 재순환 제어 밸브를 포함한다. 본 발명에 의하면 상기 연료전지에서 미반응된 수소를 상기 연료개질기로 재순환시켜 상기 연료개질기에서의 수소 수율과 상기 연료전지의 연료 효율을 증가시켜, 수중운동체의 잠항 성능을 향상시킬 수 있다.
