摘要
以影响质子交换膜燃料电池（PEMFC）性能的12个参数为研究对象，以给定电压条件下的输出电流为考核目标，通过正交设计方法与数值模拟相结合，采用模糊熵权法，将多指标转化为单指标。研究结果表明：阴极传递系数、阴极交换电流密度、氧气参考浓度、氧气在参考状态下的扩散系数是影响电池性能的主要参数，阴极传递系数与氧气在参考状态下的扩散系数、阴极交换电流密度与氧气参考浓度、阴极交换电流密度与氧气在参考状态下的扩散系数、氧气参考浓度与氧气在参考状态下的扩散系数间有很显著的交互作用。
By using 12 parameters which effect proton exchange membrane fuel cell （PEMFC） performance as reference, output current as assessment objectives under the conditions of given voltage, combined orthogonal design method and numerical simulation, using fuzzy entropy weight method, change multiple indicators into single index, the results show that cathode transfer coefficient, cathode exchange current density, oxygen reference concentration, reference diffusion coefficient of oxygen are main parameters affecting the battery performance; cathode transfer coefficient and reference diffusion coefficient of oxygen, cathode exchange current density and oxygen reference concentration, cathode exchange current density and reference diffusion coefficient of oxygen, oxygen reference concentration and reference diffusion coefficient of oxygen have significant interactions.
