A fuel cell ship is disclosed. The fuel cell ship according to an embodiment of the present invention comprises: a first storage tank storing liquefied natural gas and boil-off gas thereof; a second storage tank storing liquefied hydrogen; a heat exchange part that supercools the liquefied natural gas supplied from the first storage tank by exchanging heat with the liquefied hydrogen supplied from the second storage tank; a supercooling line that recovers supercooled liquefied natural gas toward the first storage tank; and a hydrogen supply line that supplies hydrogen gas generated by heat exchange to the fuel cell, thereby capable of reducing the amount of boil-off gas generated from liquefied gas stored inside the storage tank. 연료전지 선박이 개시된다. 본 발명의 실시 예에 의한 연료전지 선박은 액화천연가스와 이의 증발가스를 저장하는 제1저장탱크; 액화수소를 저장하는 제2저장탱크; 제1저장탱크로부터 공급받은 액화천연가스를 제2저장탱크로부터 공급받은 액화수소와 열교환하여 과냉각시키는 열교환부; 과냉각된 액화천연가스를 제1저장탱크 쪽으로 회수하는 과냉각라인; 및 열교환에 의해 생성된 수소기체를 연료전지 쪽으로 공급하는 수소공급라인;을 포함한다.
