ABSTRACT：
I：The suitability of a high surface area graphite (HSAG) as proton exchange membrane fuel cell (PEMFC) catalyst
support has been evaluated and compared with that of the most popular carbon black: the Vulcan XC72. It has been
observed that Pt is arranged on the graphite surface resulting in different structures which depend on the catalysts
synthesis conditions.
M：The influence that the metal particle size and the metal-support interaction exert on the catalysts degradation rate is
analyzed.
R：Temperature programmed oxidation (TPO) under oxygen containing streams has been shown to be a useful method
to assess the resistance of PEMFC catalysts to carbon corrosion. The synthesized Pt/HSAG catalysts have been
evaluated in single cell tests in the cathode catalytic layer.
D：The obtained results show that HSAG can be a promising alternative to the traditionally used Vulcan XC72 carbon
black when suitable catalysts synthesis conditions are used.
I：評估以高比表面積石墨作為質子交換膜燃料電池觸媒載體是否適合，並與市面上最
常用的Vulcan XC72碳黑相比較，可觀察到Pt被分佈在石墨表面形成依不同觸媒合成法
為條件所形成的結構。
M：分析金屬粒子大小以及金屬粒子與載體之間的相互影響導致觸媒退化降級速度。
R：於氧氣流動下的程序升溫氧化可視為一種有效的方法來評估PEMFC觸媒碳載體對於
退化降級的抵抗能力。Pt和高比表面積石墨的合成觸媒在單電池組測試之陰極觸媒層中
被評估。
D：結果顯示於合適的觸媒合成條件下高比表面積石墨可成功作為Vulcan XC72碳黑的
替代載體。
