Studies of the CO Tolerance for Anodes of PtFe/C in PEMFC

Abstract: The oxidation of hydrogen containing carbon monoxide was studied on Pt-Fe electrocatalysts supported on a high surface area carbon powder. A good electrocatalytic activity was observed for anodes formed by this catalyst and supplied with H2 containing 100 ppm of CO, which presented overpotential loss of 250 mV at 1 A cm-2, compared to pure hydrogen. The on line differential electrochemical mass spectrometry has shown that the production of CO2 started at low potentials for PtFe/C, confirming that the C… Show more
