Preparation and characterization of nafion modified Pt/C electrocatalyst

Pt/C-Nafion electrocatalyst was prepared by introducing Nafion 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 Nafion 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 m2/g, which is about 33.5 % higher than that of Pt/C.
