摘要:

为探明质子交换膜燃料电池 (PEMFC) 运行参数对其输出性能的影响规律,基于Simulink平台,利用Thermolib 工具包搭建Mark V型质子交换膜燃料电池分析模型,研究了电堆温度、空气湿度、空气温度、氢气压力、空气压力及空气过量系数等关键运行参数对单体电池电压的影响规律。结果表明:适当增加H2压力、空气压力以及空气湿度,可以改善电堆性能;电堆温度、空气温度以及空气过量系数对燃料电池性能影响是有一定限度的,达到最优状态后,提高参数不会改善电池的性能。该分析结果有助于理解关键运行参数对燃料电池性能的影响,对燃料电池控制策略的开发有一定的指导意义。

Abstract:

A Mark V proton exchange membrane fuel cell (PEMFC) analysis model was established to find out the influence of operating parameters on the output performance of PEMFC based on Simulink platform and Thermolib toolkit. The key operating parameters’ influence on the single cell voltage were studied, such as the stack temperature, air humidity, hydrogen pressure, air temperature, hydrogen pressure, air pressure, air excess coefficient and so on. The results show that the stack performance can be improved by increasing H2 pressure, air pressure and air humidity; the influence of stack temperature, air temperature and excess air coefficient on the performance of fuel cell is limited. When the fuel cell reaches the optimal state, increasing the parameters will not improve the performance of fuel cell. These analysis results are helpful to understand the influence of key operating parameters on the performance of fuel cell, and have certain guiding significance for the development of fuel cell control strategy.

Key words: proton exchange membrane fuel cell(PEMFC), operating parameters, performance analysis, simulation analysis
