Abstract:
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.
