Abstract

Abstract: Polarization performance of the MEA fabricated by surface roughening and solvent pre-treating of Nafion117 membrane was improved. Cyclic Voltammetry (CV) and Electrochemical Impedance Spectra(EIS) analysis suggested that the three-phases interface of catalyst/ membrane was expanded and the interface contact impedance was reduced with the roughened Nafion117 membrane as the MEA’s separator.

Key words: µ, PEMFC, MEA, Nafion117 membrane, Surface roughening, Polarization performance
