Zusammenfassung:According to at least one aspect of the present invention, there is provided a fuel cell catalyst formed from a metallic alloy of one or more catalyst metals and one or more leachable metals through potential cycling to remove at least a portion of the leachable metals such that an effective catalytic surface area of the fuel cell catalyst per a given amount of the catalyst metals is enhanced after removal of the at least a portion of the one or more leachable metals.
