Abstract: The kinetics of the CO desorption process have been investigated on a PtRu/C anode using isotopic exchange experiments under conditions of relevance to PEM fuel cells operating with reformate gas. Desorption rate constants have been determined experimentally for a wide range of concentrations (100-1000 ppm) and temperatures (25-150°C) and have been extrapolated to one order of magnitude lower CO concentration range between 10 and 100 ppm, which is directly relevant to PEMFC operating with reformate gas. The results are discussed with relation to the CO tolerance issue at the PEM fuel cell anode and to the development of more accurate models for PEM fuel cells operating with reformate gas.
