ABSTRACT:
A hydrogen-oxidizing catalyst, comprising a body of yttrium coated with a thin surface layer of copper or platinum. The catalyst is preferably in powder form, and is especially useful as the catalyst at the hydrogen electrode of a fuel cell. The copper-yttrium combination shows better catalytic activity than shiny platinum in terms of current density for a given anode voltage, and the platinum-yttrium combination is even better, although more expensive than the Cu-Y combination.
