Abstract

This invention relates to novel electrocatalyst coated electrodes and to a method for the preparation thereof for use in electrochemical cells, particularly those employing alkaline electrolytes in the anolyte compartment of the cell. The electrodes disclosed are coated with the oxides of cobalt and tungsten and are particularly suitable as anodes since the electrocatalyst coatings resist destruction by oxygen.
