Abstract
A fuel cell oxidation reduction reaction catalyst comprising a carbon substrate, an amorphous metal oxide intermediate layer on the substrate, and an intertwined matrix of platinum and elemental niobium arranged to form a surface metal layer covering the intermediate layer such that upon oxidation, the niobium binds with oxygen resulting in strengthened bonds between the platinum and the intermediate layer.
