摘要
为提高质子交换膜氢燃料电池在实际工况中的应用效率,根据实际电堆性能与质子交换膜氢燃料电池(PEMFC)的工作原理对现有的能斯特电动势模型进行改进,结合机理建模和辨识建模方法,建立效率更高、稳定性更好的新型PEMFC系统模型,基于Matlab等平台对该模型进行仿真验证分析。结果表明,新型PEMFC系统模型能够直观反映电堆输出电压、输出功率、电池效率受温度、氢氧比、压差等参数影响的变化趋势,相较于传统PEMFC系统模型,在电池效率、续航、稳定性等方面有较大提升。
In order to improve the efficiency of the proton exchange membrane fuel cell system,the existing Nernst electromotive force model was improved according to the actual stack performance and the working principle of PEMFC.By combining mechanism modeling and identification modeling methods,a new PEMFC system model with higher efficiency and better stability was established.The model was simulated,verified and analyzed based on Matlab platform.The results show that the new PEMFC system model can visually reflect the changing trends of the stack output voltage,output power,and battery efficiency affected by parameters such as temperature,hydrogen-oxygen ratio,and pressure difference.Compared with the traditional PEMFC system model,it has significant improvements in battery efficiency,endurance,and stability.
