Abstract
Bipolar electrodes with graphite as the carrier have a layer of chromium trioxide not less than 10 .mu.m thick on both the anode face and the cathode face. The electrodes are produced by plasma-spraying chromium trioxide powder onto a graphite layer, and can be used as bipolar electrodes in alkali metal chloride electrolysis cells.
