PEM燃料电池阴极催化剂层的模型及性能分析
Model of Cathode Catalyst Layer and Analysis on Performance of PEM Fuel Cells
摘要
以物质和电流平衡为基础，建立了PEM燃料电池阴极催化剂层的数学模型，并运用 逐次近似法求解此数学模型。比较发现，数值计算结果和实验结果吻合很好。同时分析了孔 隙率和催化剂表面积对催化剂层性能的影响。
The mathematical model of cathode catalyst layer of PEM fuel cell is d eveloped based on the equilibrium of mass flux and the increase of current densi ty, and the equations are solved by a relaxation method. The model is justified by comparing the result of model and that of experiment. The influence of porosi ty and active catalyst surface area on the performance of cathode is analyzed as well.
