A high-performance CO preferential oxidation (PROX) catalyst was developed for the CO removal process of residential polymer electrolyte fuel cell (PEFC) systems. A durability period of >10 years for the CO PROX catalyst was demonstrated in a single-stage CO PROX removal reactor of a natural gas fuel processor for residential PEFC systems. It was confirmed that the CO concentration was reduced to below 10 ppm, which is the required level for PEFCs, in a natural gas–reformed gas under several operating conditions by the single-stage CO PROX removal reactor over the CO PROX catalyst after 90,000 h of operation.
