The invention provides a fuel cell temperature control method, and the method comprises the following steps: acquiring a fan duty ratio under the current output power of a fuel cell at the current environment temperature, a fan duty ratio compensated by PID control and a fan duty ratio which is predicted by a model and should be output, and then adding the three fan duty ratios to obtain a final fan duty ratio; and enabling a fan controller of the cooling system to control the fan to work according to the final duty ratio of the fan so as to control the temperature of the fuel cell. The method is simple and feasible, and the temperature of the fuel cell can be rapidly and accurately reduced.

    本发明提供了一种燃料电池温度控制方法,先获取得到当前环境温度下当前燃料电池输出功率下的风扇占空比、PID控制补偿的风扇占空比和模型预测的应该输出的风扇占空比,之后将三者相加得到风扇最终占空比,散热系统的风扇控制器按该风扇最终占空比控制风扇工作以控制燃料电池温度。本发明方法简单可行,可更快更精准地降低燃料电池的温度。
