Abstract

A new CeO 2-based Cu-Pd bimetallic catalyst for low temperature water-gas shift reaction for on-board fuel cell applications was developed and the role of each metal on the catalytic performance was studied. CO conversion remained between 40 and 50 wt % until the Cu loading of 20 wt % and showed a maximum CO conversion close to 80 % when the Cu loading was increased to 30 wt %. The CO conversion decreased with further increase in Cu loading. As the Cu concentration increased, the turnover frequency of the catalyst decreased, and the CO light off temperature decreased. The catalytic performance of the laboratory-made Cu-Pd/CeO 2 was very close to that of commercial catalyst under the present experimental conditions.
