摘要： A composition useful in electrodes provides higher power capability through the use of nanoparticle catalysts present in the composition. Nanoparticles of transition metals are preferred such as manganese, nickel, cobalt, iron, palladium, ruthenium, gold, silver, and lead, as well as alloys thereof, and respective oxides. These nanoparticle catalysts can substantially replace or eliminate platinum as a catalyst for certain electrochemical reactions. Electrodes, used as anodes, cathodes, or both, using such catalysts have applications relating to metal-air batteries, hydrogen fuel cells (PEMFCs), direct methanol fuel cells (DMFCs), direct oxidation fuel cells (DOFCs), and other air or oxygen breathing electrochemical systems as well as some liquid diffusion electrodes.

摘要： A composition comprising an admixture of at least platinum particles and metal nanoparticles of metal that, when in admixture with the platinum particles, beneficially alters the characteristics of the platinum, including metals selected from one or more of the metals in groups 3-16, lanthanides, combinations thereof, and/or alloys thereof. The composition could be used to form an ink that further comprises an ionically conductive material, such as a polymer, capable of ionic networking throughout the ink composition so as to create a substantially structurally coherent mass without significantly impacting the reactivity of a substantial number of the nanoparticles. In one application, the ink may be used to form a catalyst whereby the ink is applied to an electrically conductive backing material, such as carbon paper or fibers. In another application, the ink may be used to form an electrode whereby the ink may be applied to an electrically conductive material, and wherein the ink comprises an admixture of platinum particles and metal nanoparticles.
