    摘要： A method for the installation of oxygen-consuming electrodes in electrochemical cells includes sealing one or more oxygen-consuming electrodes in an electrochemical half cell having damaged regions and/or overlap regions and applying a sealing paste. The sealing paste includes silver oxide, a hydrophobic polymer component, and a perfluorinated or partially fluorinated solvent. The method may be used, in particular, for chloralkali electrolysis. An electrochemical cell, having one or more adjoining oxygen-consuming electrodes with damaged and/or overlap regions sealed with a sealing paste having silver oxide, a hydrophobic polymer component, and a fluorinated solvent, is also disclosed.
