| 英文摘要 | the effect of graphitic carbon on the stability of pt/c catalysts for proton exchange membrane fuel cells was investigated. vulcan xc-72 carbon black was graphitized at different temperatures, and the catalyst having a platinum loading of 20% was prepared by hcho reduction-impregnation using the graphitic carbon as the support. graphitic carbons were characterized by x-ray diffraction and nitrogen adsorption-desorption methods. the catalysts were characterized by an accelerated aging test and tg analyses. the results showed that the graphitization process started at 1 500 degrees c, and the degree of graphitization increased with temperature, but the specific surface area of the carbons decreased gradually. the catalysts using the graphitic carbons as the support showed better electrochemical stability. |
