| 摘 要： | 以改性酚醛树脂为粘合剂,炭纤维纸为坯体,通过浸渍、模压固化、炭化、石墨化工艺制得质子交换膜燃料电池气体扩散层用炭纸,表征了炭纸的基本性能并与东丽炭纸的相关性能进行了对比。结果表明,自制炭纸的厚度为0.189mm,密度为0.446g/cm3,均与东丽炭纸相近;孔隙率为83%,比东丽炭纸提高18.6%;体电阻率为3.35mΩ.cm,面电阻率为3.86mΩ.cm,分别比东丽炭纸减小了25.9%和39.7%;压差为88.2Pa时透气率达5100mL.mm/(cm2.h.mmAq),比东丽炭纸提高了41.67%;抗拉强度为29.98MPa,比东丽炭纸提高约16.5%;与东丽炭纸相比,自制炭纸的电压输出性能略有下降但不明显。

| Abstract: | The carbon paper was improved to be fit for the use of gas diffusion layer in proton exchange membrane fuel cell by the process of impregnation,molding,carbonizating,graphitization,with modified phenolic resin as the binder and carbon fiber paper as the green body.Fundamental properties were characterized and compared with Toray carbon paper.The results show that,thickness is 0.189mm,density 0.446g/cm3,which are almost the same with Toray′s;the porosity is 83%,18.6% higher than Toray′s;through-plane resistivity 3.35mΩ·cm and in-plane resistivity 3.86mΩ·cm,25.9% and 39.7% lower than Toray carbon paper respectly;permeability rate reaches 5100mL·mm/(cm2·h·mmAq) at 88.2Pa,41.67% higher than Toray′s;the output voltage performance is a little worse than Toray′s but not soevident. |
