中文摘要：

通过在合成过程中引入质子导体Nafion聚合物,制备了Pt/C-Nafion电催化剂。采用热重（TG）、元素分析（EDS）、X射线衍射（XRD）、透射电镜（TEM）及电化学方法对该催化剂进行了表征。结果表明,与Pt/C电催化剂相比,Pt/C-Nafion中Nafion聚合物的引入使得电催化剂的分散性有所提高,以Pt/C-Nafion为阴极催化剂的直接甲醇燃料电池阴极催化层中的电化学活性表面积（ECSA）达到23.61m^2/gPt,比Pt/C催化剂提高近33.5%。

英文摘要：

Pt/C-Nafion electrocatalyst was prepared by introducing Nation polymer during the synthesis process, which was characterized by Thermogravimetry （TG）, Energy Dispersive Spectrometer （EDS）, X-ray diffraction （XRD）, transmission electron microscope （TEM） and electrochemical method. The results show that comparing with Pt/C electrocatalyst, the introduction of Nation makes better particle distribution in Pt/C-Nafion, and the electrochemical surface area （ECSA） of the catalyst layer with Pt/C-Nafion is 23.61 m^2/g, which is about 33.5 % higher than that of Pt/C.
