摘要
从电化学的角度分析了质子交换膜燃料电池(PEMFC)的极化特性,在此基础上针对其主要工作区在欧姆极化段的特点,通过测算出不同温度、操作压力条件下的等效热力学电动势与电池堆内阻,建立了一个简单实用的稳态电压模型。最后通过对一个500 W的PEMFC发电系统的稳态负载实验,验证了模型的建立是可行和合理的。
The polarization characteristics of the proton exchange membrane fuel cell(PEMFC) was theoretically analyzed as viewed from electrochemistry.On this basis,a simple and practical steady voltage model of PEMFC was built through predetermining its equivalent thermodynamics electromotive force and internal resistance under different temperatures and pressures,since the PEMFC mainly works in the ohmic polarization area.In the end,a 500 W PEMFC system was tested,and the result proves that the model is feasible and reasonable.
