Abstract:
1. A process for producing an oxygen-consuming electrode, comprising the steps of: a) precipitating silver oxide by simultaneously adding an aqueous NaOH solution and a silver nitrate solution to a receiver vessel to form a suspension, using a mechanical stirrer to introduce a stirring energy in the range from 0.01 W/l to 10 W/l, in the course of which the pH is kept constant within the range from pH 10 to 12 and the temperature is kept within a range from 20° C. to 80° C., b) removing the precipitated silver oxide from step a) from the suspension, c) drying the silver oxide at a temperature in the range from 80° C. to 200° C., d) further processing the resulting silver oxide with an electrically conductive carrier material, a catalyst comprising silver particles, and a finely divided fluorinated polymer to give a flat oxygen-consuming electrode.
