The invention provides a fuel cell comprehensive thermal management system and a fuel cell electric vehicle. The system comprises an electric pile; a warm air loop, wherein an input port of the warm air loop is connected with an output port of the electric pile, an output port of the warm air loop is connected with an input port of the electric pile, and the warm air loop is used for heating a flowing refrigerant fluid and heating a to-be-heated area, wherein the refrigerant fluid is output after being heated by the warm air loop and then flows to the electric pile, so that the working temperature of the electric pile is ensured. The refrigerant fluid is heated through the warm air loop, so that the working temperature of the electric pile is ensured, for example, when the electric pile is not started, the temperature required for starting the electric pile is ensured through the refrigerant fluid heated by the warm air loop; besides, according to the fuel cell comprehensive heat management system, the compartment of the fuel cell electric vehicle is heated through an anti-freezing solution when the electric pile is not started through the warm air loop, the requirement of a user for warm air is met, meanwhile, the structure of an original vehicle heating system is slightly changed, and the fuel cell comprehensive heat management system has the advantages of being energy-saving, simple in structure, small in applicable area limitation and the like.
本发明提供了一种燃料电池综合热管理系统及燃料电池电动车,其中,该系统包括:电堆;暖风回路,输入口连接电堆的输出口,输出口连接电堆的输入口,用于对流经的冷媒流体进行加热以及对待供热区进行供暖;其中,冷媒流体经暖风回路加热后输出,再流至电堆,以对保证电堆的工作温度。通过暖风回路对冷媒流体进行加热,保证了电堆的工作温度,如:在电堆未启动时,通过经暖风回路加热的冷媒流体保证了电堆启动所需的温度;此外,该燃料电池综合热管理系统也通过暖风回路在电堆未开启时防冻液为燃料电池电动车的车厢内供暖,满足了用户对暖风的需求,同时对原车供暖系统结构改动较小,具有节能、结构简单、适用区域限制小等优点。
