OXYGEN-CONSUMING ELECTRODE AND PROCESS FOR PRODUCTION THEREOF

摘要

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 is based on a gas diffusion layer as a porous film of a fluorinated polymer, into which fine crystal needles of a catalyst metal have been introduced as the catalytically active component and are connected with electrical conduction to the current collector.
