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.

Gas diffusion electrodes and process for production thereof

A multilayer oxygen consuming electrode having a side facing the oxygen-containing gas and a side facing the alkaline electrolyte, wherein the electrode includes at least one support, and at least two layers containing a catalyst and a hydrophobic material, wherein the outermost layer facing the gas side has a lower proportion of catalyst than the outermost layer facing the electrode side and wherein the proportion of hydrophobic material is not more than 8% by weight based on the total amount of the catalyst the hydrophobic material.

Oxygen-consuming electrode with multilayer catalyst coating and process for the production thereof

The invention describes an electrode and an electrode coating which are based on a catalyst containing finely divided carbon modifications and noble metal (oxide)s.
