摘　　要：研究双极板与气体扩散层接触电阻的形成机理,分析影响该接触电阻的因素,包括温度、载荷以及粗糙度等参数。通过建立数学模型以及利用仿真工具来预测接触电阻数值与变化规律,并进行金属双极板和碳纸气体扩散层的界面接触电阻测试用于模型验证,模型计算结果与实验结果吻合较好。The formation mechanism of contact resistance between bipolar plate and gas diffusion layer is studied.The factors affecting the contact resistance are analyzed,e.g.,temperature,load,and roughness.A mathematical model is established and used to predict the values and variation rule of the contact resistance by means of a simulation tool.Tests are carried out on the interface contact resistance of the metallic bipolar plate and carbon paper layer for verification.It is shown that the calculated results agree well with the test data.
