Study on Pt-SnO2/C Electrode Prepared by Different Content of Nafion for New Direct Ethanol Fuel Cells


Article Preview

A carbon supported Pt-SnO2/C catalyst was prepared by hydrothermal method .The Pt-SnO2/C electrode was prepared by electrostatic spinning. Factors of product in solution, different Nafion loading and different loading of Pt-SnO2/C catalyst were evaluated for their effects on ethanol oxidation reaction (EOR). Electrocatalyst was characterized by SEM,EDS and XRD. At the same time, Electrocatalyst was tested by cyclic voltammetry (CV) , Chronoamperometry, AC impedance at three-electrode under similar conditions to those of the DEFC. The results show that the Nafion loadings was 7.5wt.%, which the loading amount of Pt was 1.5mg•cm-2, the Pt-SnO2/C electrode has the highest activity for ethanol oxidation. Compared to the low potential, the oxidation peak current density was 2 times high obtained.
