The invention relates to a fuel cell temperature control method, device and system, a vehicle and a storage medium, and relates to the technical field of batteries, the method comprises the following steps: determining the error of the inlet temperature of a fuel cell based on the change type of the inlet temperature of the fuel cell and the predicted inlet temperature of the fuel cell; determining a target opening degree of a three-way valve in the fuel cell cooling system based on the error of the inlet temperature of the fuel cell; and adjusting the opening degree of a three-way valve in the fuel cell cooling system based on the target opening degree, so that the actual inlet temperature of the fuel cell reaches the preset temperature. Therefore, the target opening degree of the three-way valve can be determined according to the change trend and change characteristics of the inlet temperature of the fuel cell, so that the opening degree of the three-way valve in the fuel cell cooling system is adjusted in advance according to the target opening degree, the time delay of temperature adjustment is reduced, and the actual inlet temperature of the fuel cell is closer to the preset temperature; and the control accuracy of the inlet temperature of the fuel cell is improved.

    本申请涉及一种燃料电池温度控制方法、装置、系统、车辆及存储介质,涉及电池技术领域,该方法包括:基于燃料电池入口温度的变化类型和燃料电池的预测入口温度,确定燃料电池入口温度的误差;基于燃料电池入口温度的误差,确定燃料电池冷却系统中三通阀的目标开度;基于目标开度调整燃料电池冷却系统中三通阀的开度,以使得燃料电池的实际入口温度达到预设温度。由此,可以根据燃料电池入口温度的变化趋势和变化特点确定三通阀的目标开度,从而根据目标开度提前调整燃料电池冷却系统中三通阀的开度,降低温度调节的时间滞后,使燃料电池的实际入口温度更接近预设温度,提高了燃料电池入口温度控制的精准度。
