摘要
质子交换膜燃料电池(proton exchange membrane fuel cell,PEMFC)具有能量转换效率高、相对于传统发动机振动低和噪声低及使用可靠等优点,逐渐成为研究的重点。燃料电池的系统建模需要掌握电学、电化学、热力学、流体力学等知识,提高了系统研究的门槛和复杂度。为了研究质子交换膜燃料电池系统特性,借助AMESIM建立一种燃料电池模型,在此基础上,分析燃料电池的电学特性。发现质子交换膜的厚度、气体扩散层和空气流速对电池性能有影响。
Proton exchange membrane fuel cell(PEMFC)has been valued by people for its high energy conversion efficiency,low noise,high reliability and high maintainability.The construction of fuel cell model covers many disciplines,including electricity,electrochemistry,thermodynamics and fluid mechanics,which makes relative studies difficult.In order to study the characteristics of proton exchange membrane fuel cell system,we used AMESIM to establish a fuel cell model,on the basis of which,the electrical characteristics of the fuel cell were analyzed.The thickness of the proton exchange membrane,the gas diffusion layer,and the air flow rate were found to have influences on the battery performance.
