Abstract
An anode structure comprising a ruthenium catalyst is disclosed. The catalyst consists essentially of ruthenium deposited on a conducting support wherein the ruthenium is in metallic form or in a form that is readily reducible to the metallic form at temperatures of 25° C. to 150° C. The anode structure is particularly of use in proton exchange membrane fuel cell to prevent poisoning of the electrocatalyst by impurities in the fuel stream to the anode.
