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.
