The present invention relates to a fuel cell power generation system and a vessel equipped with the system. The fuel cell power generation system (100), according to the present invention, comprises: an ammonia reformer (320) thermally decomposing ammonia; a cooler (380) cooling the high-temperature mixed gas containing undecomposed ammonia, hydrogen, and nitrogen discharged from the ammonia reformer (320); an ammonia adsorber (330) adsorbing undecomposed ammonia in the mixed gas cooled from the cooler (380); a nitrogen adsorber (340) adsorbing nitrogen from the mixed gas in which undecomposed ammonia is adsorbed through the ammonia adsorber (330); and a polymer electrolyte fuel cell unit (360) generating power using hydrogen decomposed from ammonia, wherein the ammonia adsorber (330) is regenerated through the high-temperature mixed gas discharged from the ammonia reformer (320). The present invention can provide a fuel cell power generation system suitable for ships or vehicles, comprising a polymer electrolyte fuel cell unit capable of operating at a relatively low temperature without leakage of electrolyte. 본 발명에 따른 연료전지 발전시스템(100)은 암모니아를 열분해하는 암모니아 개질기(320), 암모니아 개질기(320)에서 배출되는 미분해 암모니아, 수소 및 질소를 포함하는 고온의 혼합가스를 냉각시키는 냉각기(380), 냉각기(380)로부터 냉각된 혼합가스에서 미분해 암모니아를 흡착하는 암모니아 흡착기(330), 암모니아 흡착기(330)를 통해 미분해 암모니아가 흡착된 혼합가스로부터 질소를 흡착하는 질소 흡착기(340), 및 암모니아로부터 분해된 수소를 이용하여 전력을 생산하는 고분자 전해질 연료전지부(360)를 포함하고, 암모니아 흡착기(330)는 암모니아 개질기(320)에서 배출되는 고온의 혼합가스를 통해 재생되는 것을 요지로 한다.
