The invention belongs to the technical field of fuel cell vehicles, and particularly relates to a thermal management method, device and system of a fuel cell. The thermal management method of the fuelcell comprises the steps of acquiring a current temperature value in a vehicle; and according to the fact that the current temperature value in the vehicle is less than a first preset temperature value, controlling cooling liquid of an engine to exchange heat with a refrigerant of a first radiator in the vehicle. According to the thermal management method of the fuel cell in the invention, the cooling liquid of the engine is controlled to exchange heat with the refrigerant of the first radiator in the vehicle according to the fact that the current temperature value in the vehicle is less thanthe first preset temperature value, waste heat of the fuel cell engine is fully utilized, heat of the cooling liquid of the radiator is introduced into the vehicle to heat the interior of the vehicle, the heat exchange efficiency is improved, energy is saved, and the heating requirement of the whole vehicle in winter is met.

    本发明属于燃料电池车辆技术领域,具体涉及一种燃料电池的热管理方法、装置及系统。本发明的燃料电池的热管理方法包括如下步骤:获取车内的当前温度值;根据车内的当前温度值低于第一预设的温度值,控制发动机的冷却液与车内的第一散热器的制冷剂交换热量。根据本发明的燃料电池的热管理方法中,根据车内的当前温度值低于第一预设的温度值,控制发动机的冷却液与车内的第一散热器的制冷剂交换热量,充分利用燃料电池发动机余热,将散热器冷却液热量引入车内,对车内进行加热,使换热效率增加,节约能量,用于整车冬季采暖需求。
