  • Gas diffusion electrodes, membrane-electrode assemblies and method for the production thereof
    Patent number: 8460841
    Abstract: A method for forming a mixed metal coating on a gas diffusion medium substantially free of ionomeric components which includes the steps of subjecting an electrically conductive web to a first ion beam having an energy not higher than 500 eV, then to a second beam having an energy of at least 500 eV containing the ions of a first metal, and to at least a third beam having an energy of at least 500 eV containing the ions of a noble metal. The invention also relates to gas diffusion electrodes.

  • Carbon supported metal alloy catalysts and method for the manufacturing thereof
    Publication number: 20050209098
    Abstract: A carbon supported metal alloy catalyst obtained by first depositing a noble metal on a carbon support and subsequently selectively depositing at least one second metal on the thus-obtained carbon-supported noble metal in an aqueous environment, wherein said selective deposition is obtained by reduction of a precursor of said second metal with hydrogen gas, said reduction being catalyzed by said noble metal and localized in correspondence thereto and a method for its production.
