The present invention is to provide a heat pump system for fuel cell vehicles. According to the present invention, a flash tank in which refrigerant circulates is connected to a predetermined location in a heat management refrigerant cycle system, and a heat exchanger is built into the flash tank through which the produced water discharged from a fuel cell stack circulates so that heat exchange for cooling and heating between the refrigerant circulating inside the flash tank and the produced water circulating through the heat exchanger in the flash tank can be implemented. Thus, indoor cooling and heating efficiency can be improved, and operation efficiency of the fuel cell system to increase driving range by reducing heating and cooling loads can be improved.

    본 발명은 열관리용 냉매 사이클 시스템의 소정 위치에 냉매가 순환하는 플래시 탱크를 연결하고, 플래시 탱크 내에 연료전지 스택에서 배출되는 생성수가 순환하는 열교환기를 내장하여, 플래시 탱크의 내부를 순환하는 냉매와 플래시 탱크 내의 열교환기를 순환하는 생성수 간의 냉난방 등을 위한 열교환이 이루어질 수 있도록 함으로써, 실내 냉난방 효율을 향상시킬 수 있고, 냉난방 부하 절감으로 주행가능거리 증대 등을 위한 연료전지 시스템의 운전 효율 향상을 도모할 수 있도록 한 연료전지 차량용 히트펌프 시스템을 제공하고자 한 것이다.
