OXYGEN-CONSUMING ELECTRODES AND PROCESSES FOR THE PRODUCTION THEREOF

Oxygen-Consuming Electrodes and Processes for the Production ThereofThe present invention relates to a multilayer oxygen-consuming electrode having a side facing theoxygen-containing gas and a side facing the alkaline electrolyte, wherein the electrode includes at least one support, and at least two layers comprising 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 electrolyte side and wherein the proportion of hydrophobic material is not more than 8% by weight based on the total amount of the catalyst and the hydrophobic material.Figure : None
