Abstract (en)

[origin: WO2017174563A1] The invention relates to an oxygen-consuming electrode for use in chlor-alkali electrolysis which, as required, can either evolve hydrogen or can also consume oxygen, on the basis of a silver-based catalyst and an additional electrocatalyst based on ruthenium and/or iridium. The invention further relates to an electrolysis device consisting thereof. When said electrode is used in the chlor-alkali electrolysis, a correspondingly equipped chlor-alkali electrolysis system can be used for example for network stabilization of power supply networks.
