Abstract
Disclosed are catalysts, especially catalytic anodes, useful for catalyzing reactions in fuel cells and in other environments. The catalysts have a substrate base made of iridium and/or ruthenium. There is a very thin coating on the substrate which is a mix of platinum and at least one metal selected from gold, palladium, iridium, rhodium, ruthenium, rhenium, and osmium. The anodes are resistant to carbon monoxide adulteration in fuel cells.
