| Abstract: The electrochemical surface area (ESA) of the half-membrane electrode assembly (HMEA) and dimethyl-ether (DME) electrooxidation on the HMEA were examined by cyclic voltammetry (CV). The ESAs of the electrode before and after DME electrooxidation were calculated from the integrated charge during the adsorption (and/or desorption) of atomic hydrogen minus the charge for the double layer charging in 0.5 mol·L-1 H2SO4. The increase in ESA was observed, and this was attributed to the change of catalyst layer structure, leading to a more effective contact between catalysts and the electrolyte Nafion. |
