Poly-(3,4-ethylenedioxythiophene) (PEDOT) was applied in making electrodes and gas diffusion layer for direct methanol fuel cells (DMFC). Electrochemical characterizations of Pt/PEDOT electrodes, made by two different methods, were investigated by cyclic voltammetry, methanol oxidation tests and DMFC performance. The platinum particle structure in PEDOT/PSS (polystyrene sulfonic acid) films was investigated by SEM and TEM. Our research work showed that PEDOT influenced the catalytic activity behavior in three different ways when it was applied to the anode, cathode and the gas diffusion layer. The DMFC performance agreed with the cyclic voltammetry and methanol oxidation test results.
