| 摘 要： | 研究了一种用于质子交换膜燃料电池(PEMFC)的自制Pt/C电催化剂(标记为THYT-1)的物理化学和电化学性质.将THYT-1电催化剂与E-TEK公司的同类电催化剂的组成、形态及电催化性能进行了比较.单电池测试结果显示, THYT-1的电催化性能优于E-TEK电催化剂. CV测试结果表明CO在这两种电催化剂上的电氧化性能相近；TEM分析表明两种催化剂上Pt晶粒在炭载体上呈均匀分布，平均粒径均为2～3 nm； XPS和XRD测试结果表明两种催化剂中Pt主要以金属态存在.这些数据表明THYT-1催化剂的物理化学性质与E-TEK公司的相类似.

| Abstract: | A homemade Pt/C electrocatalyst(named as THYT-1) for proton-exchange membrane fuel cell(PEMFC) was prepared and characterized comprehensively. Single-cell measurements showed that the performance of THYT-1 for hydrogen electro-oxidation was superior to that of the E-TEK Pt/C catalyst. Cyclic voltammetry measurements in a half PEM fuel cell indicated that the electro-oxidation behavior of adsorbed CO on THYT-1 and the E-TEK Pt/C catalyst was indistinguishable. XPS and XRD detections showed that platinum of the two catalysts exist mainly in the metallic state. Uniformly dispersed Pt-particles with sizes of 2～3 nm were found to be the dominant images of Pt in the TEM micrographs for both THYT-1 and the E-TEK catalysts. Application of THYT-1 catalyst in the research and development of PEMFC technology can be expected. |
