PEMFC碳载体抗腐蚀能力研究
Study of carbon support corrosion in PEMFC
摘要
Abstract
Carbon support corrosion would lead to the degradation of catalyst and further the decrease of PEMFC performance. ln this paper, the corrosion behaviors of XC72, MWNT and graphitic XC72 were studied by potentiodynamic and chronoamperometric methods. The results show that, graphitic XC72 has the best corrosion resistant ability, then MWNT, and the last is XC72. The temperature has a very big influence on support corrosion.With the increase of temperature, the support corrosion current increases, and the corrosion current of XC72 increases faster than MWNT and graphitic XC72. Pt also influences support corrosion significantly. After the loading of Pt on support, the support corrosion is promoted. Pt/Graphitic XC72 is shown to have the best corrosion resistant ability, then Pt/MWNT, and the last is Pt/XC72.关键词
