Abstract
An oxygen-consuming electrode is described, more particularly for use in chloralkali electrolysis, comprising a novel catalyst coating, as is an electrolysis apparatus. Also described is a production process for the oxygen-consuming electrode and the use thereof in chloralkali electrolysis or fuel cell technology. The oxygen-consuming electrode comprises at least an electrically conductive support, an electrical contact site and a gas diffusion layer comprising a catalytically active component, characterized in that the coating at least one fluorinated polymer, silver in the form of silver particles and silver oxide in the form of silver oxide particles, which is produced in a selected precipitation step.
