OXYGEN-CONSUMING ELECTRODE AND METHOD FOR ITS PRODUCTION

A silver oxide is precipitated at 20-80[deg] C by simultaneously adding an aqueous sodium-hydroxide solution and silver nitrate solution to receiver vessel, using a mechanical stirrer to introduce stirring energy of 0.01-10 W/l, and pH is maintained constant to 10-12. The precipitated silver oxide is removed from the suspension. The silver oxide is dried at 80-200[deg] C. The silver oxide is processed with an electroconductive carrier material to obtain a flat oxygen-consuming electrode.

The precipitated silver oxide is removed from the suspension. The silver oxide is dried at 80-200[deg] C, optionally under reduced pressure and under inert gas atmosphere. The silver oxide is processed with an electroconductive carrier material, catalyst comprising silver particles, and finely-divided fluorinated polymer to obtain a flat oxygen-consuming electrode. An independent claim is included for electrolysis cell for electrolysis of alkali metal chloride, which comprises oxygen-consuming electrode as cathode.
