Abstract

Anode catalysts for a fuel-cell system were evaluated by employing a porous microelectrode technique in a 0.5 mol dm<sup>−3</sup> H<sub>2</sub>SO<sub>4</sub> aqueous solution. An anodic current for carbon monoxide (CO) oxidation was observed under a 1000 ppm-CO-containing hydrogen atmosphere, in which the onset potential based on CO oxidation at Pt-Ru/C shifted toward cathodic direction from that at Pt/C. In a measurement of CO-stripping voltammetry, the onset potential of CO oxidation well agreed with that of CO-containing hydrogen at Pt-Ru/C. However, in the case of Pt/C, the onset potentials were not the same. This suggests that the CO adsorptions at Pt/C and Pt-Ru/C were different in terms of energetics.<br>
