摘要
以某款PEMFC为主要研究对象,通过分析活化过电压、欧姆过电压以及浓差过电压等多种数学描述,依据经验公式构造了PEMFC数学模型。在Simulink中搭建PEMFC稳态仿真模型,研究了工作温度、阳极氢气和阴极氧气的分压力、质子交换膜含水量各因素对PEMFC输出性能的影响。结果表明:仿真结果与典型燃料电池极化特性曲线基本相同,PEMFC模型具有良好的稳态性能,为其后续进一步优化提供参考。
Taking a certain PEMFC as the main research object, the mathematical model of PEMFC is constructed according to its empirical formula by analyzing various mathematical descriptions of activation overvoltage, ohmic overvoltage and concentration overvoltage. The steady-state simulation model of PEMFC was built in Simulink, and the effects of operating temperature, partial pressure of anode hydrogen and cathode oxygen, water content of proton exchange membrane on the output performance of PEMFC were studied. The results show that the simulation results are basically the same as the polarization characteristic curves of typical fuel cells,and the PEMFC model has good steady-state performance, which provides a theoretical reference for its further optimization.
