The present invention relates to a fuel cell system of an underwater vehicle. The fuel cell system of an underwater vehicle according to an embodiment of the present invention, comprises: a fuel reformer for generating a reformed gas containing a large amount of hydrogen through fuel reforming; a hydrogen purifier for receiving the reformed gas generated in the fuel reformer to purify the reformed gas with hydrogen of high purity; a fuel cell for receiving hydrogen of high purity, which is purified in the hydrogen purifier, to generate electric energy; and a reformed gas pressure control unit provided between the fuel reformer and the hydrogen purifier, and constantly controlling pressure of the reformed gas supplied to the hydrogen purifier from the fuel reformer. The reformed gas pressure control unit includes a pressure control valve for low pressure, which receives a reformed gas of low pressure to constantly control the pressure of the reformed gas at an inlet of the hydrogen purifier, and a pressure control valve for high pressure, which receives a reformed gas of high pressure to constantly control the pressure of the reformed gas at the inlet of the hydrogen purifier.

    본 발명은 수중운동체의 연료전지시스템에 관한 것으로서, 본 발명의 일 실시예에 따른 수중운동체의 연료전지시스템은 연료개질을 통해 다량의 수소를 포함하는 개질가스를 생성하는 연료개질기, 상기 연료개질기에서 생성된 개질가스를 공급받아 고순도 수소로 정제하는 수소정제기, 상기 수소정제기에서 정제된 고순도 수소를 공급받아 전기에너지를 생성하는 연료전지, 및 상기 연료개질기와 상기 수소정제기 사이에 구비되며, 상기 연료개질기에서 상기 수소정제기로 공급되는 개질가스의 압력을 일정하게 조절하는 개질가스 압력조절부를 포함한다. 상기 개질가스 압력조절부는 저압의 개질가스를 공급받아 상기 수소정제기 입구에서의 개질가스 압력을 일정하게 조절하는 저압용 압력제어밸브, 및 고압의 개질가스를 공급 받아 상기 수소정제기 입구에서의 개질가스 압력을 일정하게 조절하는 고압용 압력제어밸브를 포함한다.
