TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The catalyst comprises silver as a catalytically active component.    TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Components: The electrode exhibits a total loading of the catalytically active component of 100-300 mg/cm2, preferably 140-250 mg/cm2. The thickness of the electrode is 0.2-0.8 mm.    TECHNOLOGY FOCUS - POLYMERS - Preferred Method: The catalyst-containing layers are generated by applying a suspension containing silver particles on the carrier, drying the suspension, hot-pressing the layers, and subsequently sintering the resulting electrode. Preferred Components: There are at least two layers, where the layer of the side facing the gas side exhibits a catalyst proportion of 92-98 wt.%, and the layer facing the electrolyte side exhibits a catalyst proportion of 95-99.9 wt.%, where the proportion of the catalytic layer supplemented up to 100% is based on the hydrophobic polymer. The silver is used in the form of powder for the suspension, where the particle distribution of the silver particles exhibits a D90-value of less than 8 mu m and a D10-value of less than 1 mu m. The knocking density of the silver particles for the suspension is 2-6 g/cm3, preferably 3-5 g/cm3. The average surface area of the silver powder is 0.3-2.5 m2/g, preferably 0.5-1.5 m2/g according to Brunauer-Emmett-Teller. There are at least three layers, where the outermost layer facing the gas side exhibits a catalyst proportion of 92-98 wt.%, and the outermost layer facing the electrolyte side exhibits a catalyst proportion of 95-99.9 wt.%, and a middle layer is present that exhibits a catalyst proportion of more than the outermost layer facing the gas side and less than the outermost layer facing the electrolyte side. The hydrophobic layer exhibits the hydrophobic polymer, preferably fluorine-substituted polymer, preferably polytetrafluoroethylene (PTFE). The carrier is based on nickel and/or silver. The carrier is present in the form of meshes, woven fabrics (preferred), knit fabrics, knitted fabrics, non-woven fabrics or foams. The thickness of the catalyst-containing layers is up to 0.4 mm. EXAMPLE - Aqueous suspension comprising a silver catalyst, Dyneon (RTM: Polytetrafluoroethylene suspension) (58 wt.%), Triton X-100 (RTM: Non-ionic surfactant) and Walocel MKX 70000 PP 01 (RTM: Hydroxyethyl methylcellulose) as a thickener was prepared with different amounts of silver (97 wt.%) and PTFE (3 wt.%). The preparation of the suspensions with a silver content of 98 wt.% and 99 wt.% was also carried out similarly. Then the silver powder (90 g), water (53.7 g) and the surfactant (1.5 g) were added into 150 g of the thickener solution (1 wt.% of methyl cellulose in water). After dispersing the suspension in a rotor-stator-system at 13500 min-1 for 5 minutes, the PTFE-solution (4.8 g) was slowly added under stirring to avoid agglomeration. The loading was chosen in such a manner that 50% of the catalyst-loading was applied in the middle of the electrode, and 25% of the catalyst-loading was respectively applied on the electrolyte side and the gas side of the electrode. The prepared suspensions were repeatedly sprayed on a nickel mesh, where the mesh was maintained at 100 degrees C during spraying, until the total loading of the catalyst was 170 g/cm2. Then the electrodes were fixed between two metal plates, and hot-pressed at 130 degrees C and a pressure of 0.14 t/cm2. Subsequently, the electrode was heated in air at 3 K/minute, and sintered at 340 degrees C for 15 minutes to obtain the three-layered oxygen-consuming electrode.
