Abstract
A process for producing a catalytically active gas diffusion electrode, in which process a gas-permeable membrane is first covered by a structuring mask which has recesses in accordance with the planned electrode surfaces. Next, through vapor deposition or cathodic sputtering of a conductive substance in a vacuum, a conductive electrode pattern structured in accordance with the recesses is produced on the membrane. After this, the conductive electrode pattern located on the membrane is galvanically coated with the catalyst by electrolytic deposition and then made hydrophobic.
