提高质子交换膜燃料电池用碳纤维纸均匀性的研究
Study on Improving the Uniformity of Carbon Fiber Paper for Proton Exchange Membrane Fuel Cell
摘要
Abstract
Using polyacrylonitrile-based short carbon fiber as the raw material,the carbon fiber paper(referred to as carbon paper)base pa-per was prepared by wet forming process,the surface morphology,chemical structure and element valence of carbon fiber under different treatment conditions were characterized by modern analytical instruments.The dispersion of carbon fiber under different treatment condi-tions and the uniformity of the prepared carbon paper base paper were observed,and the optimum condition for high-temperature air oxida-tion treatment was studied.The results showed that after high-temperature air oxidation treatment,the content of oxygen element and oxygen-containing functional group on the surface of carbon fiber significantly increased,the dispersion of carbon fiber in water was obviously en-hanced,and the uniformity of the carbon paper base paper was significantly improved with the variation coefficient of resistivity decreased from 0.22 to 0.05.The best treatment condition of high-temperature air oxidation modified carbon fiber was at 500 ℃ for 2 h.关键词
