Abstract
Official abstract text for this publication.
A gas diffusion electrode is described, especially for use in chloralkali electrolysis, said gas diffusion electrode having finely divided components on the liquid side. The electrode is notable for a low perviosity to gases and a lower operating voltage.
First claim
Opening claim text (preview).
The invention claimed is: 1. An oxygen-consuming electrode comprising (1) at least one carrier in the form of a flat structure, (2) a coating with a gas diffusion layer, and (3) a catalytically active component comprising silver, silver(I) oxide, silver(II) oxide, or mixtures thereof, wherein the oxygen-consuming electrode further comprises hydrophilic pores with an entry, and a finely divided hydrophilic component having a specific surface area in the range of from 8 to 12 m 2 /g,…
