| 摘 要： | 采用石墨化PAN系炭纤维布制备了高分子电解质燃料电池气体扩散层。通过电学实验、X-ray绕射与元素分析考察了所制气体扩散层的性能。结果表明：随热处理温度的升高，气体扩散层的电阻率降低，L2增加，d（x）2减小。高温处理后的炭纤维布作为高分子电解质燃料电池气体扩散层显示了较高的电池效能。

| Abstract: | Gas diffusion layers(GDL)in proton exchange membrane fuel cells were prepared by graphitization of polyacrylonitrile carbon fiber cloths,to enhance their properties,such as,electrical conductivity,which was examined by electrical tests,X-ray diffraction,and elemental analysis.The results indicated that electrical resistivity declined,Lc increased,and d002 decreased with an increase in the heat-treatment temperature.Carbon fiber cloths with a higher heat-treatment temperature performed better as GDLs in terms of current density and power density. |
