摘要
分别以松木炭和VulcanXC 72炭为载体制得炭载铂电催化剂 ,在聚合物电解质膜燃料电池 (PEMFC)中对其性能进行了比较。结果表明 :VulcanXC 72炭作载体的电催化剂性能显著优于松木炭作载体的电催化剂 ,利用多种分析方法对活性炭的物理和表面化学性质进行了系统的研究 ,发现活性炭的孔径。
The Pt/C catalysts were prepared with pine active carbon and Vulcan XC-72 active carbon as the supports. The performances of the Pt/C catalysts in polymer electrolyte membrane fuel cell were compared. The result indicates that the performance of Pt/Vulcan XC-72 is better than that of Pt/pine. The physical and chemical properties of the two active carbons were measured using several analysis techniques. It was found that the pore size, specific conductivity and the surface function group significantly influence the performance of the electrocatalyst.
