  • Gas diffusion electrodes, membrane-electrode assemblies and method for the production thereof
    Publication number: 20050279643
    Abstract: A method for forming a noble metal coating on a gas diffusion medium substantially free of ionomeric components comprising 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 at least one noble metal and electrodes provided by the method.
    Type: Application
