Abstract
A series of carbon supported electrocatalysts, Pt/C, Pt/WO3/C, Pt-Ru/C , and Pt-RU/WO3/C, were prepared by freeze drying and tested as Teflon -bonded electrodes in 0.5 M H2SO4 in a stream of impure hydrogen conta ining 100 ppm of CO at 80 degrees C. The first three catalysts were gr adually poisoned and the performance was less than 100 mA/cm(2) at 200 mV vs. SHE. However, there was no change in the performance of the Te flon-bonded Pt-RU/WO3/C electrode at 220 mA/cm(2) over a test period o f h.
