摘　　要：质子交换膜燃料电池(Proton Exchange Membrane Fuel Cell;PEMFC)是燃料电池中最常见的类型,也是最有希望在近年内完成技术积累,从而推向商业化的车用新能源动力系统之一。根据PEMFC的结构和工作原理,构建了PEMFC的数学模型和单电池系统仿真模型。研究了在293~353 K温度区间,温度逐渐升高,PEMFC的输出电压、活化过电压、欧姆过电压、浓差过电压、功率、效率等性能随温度变化的规律,并应用回归分析的方法,分析了输出电压、活化过电压、电池功率随温度变化的趋势,得到了令人满意的结果,为实验研究提供了理论和方法依据。Proton Exchange Membrane Fuel Cell（ PEMFC） is the most common type of fuel cells. It is one of the most promising new technologies in recent years to complete the accumulation of technology and could been used in business. Based on the structure and working principle of PEMFC,this paper constructs the mathematical model of PEMFC and the simulation model of single cell system. The changes of the output voltage,the activation voltage,the concentration voltage,the Ohm voltage,power and efficiency of PEMFC with temperature are studied under the temperature change of 293 - 353 K,and the method of regression analysis is used to analyze the output voltage,activation overvoltage,battery power,and satisfactory results are obtained which provide a theoretical basis for experimental research.
