Abstract
Bipolar electrodes are provided for electrolysis cells of the filter-press type with incorporated cathode and/or anode frames. These frames are integrated in the bimetallic base plate of the electrode serving as reference plane, perpendicularity with respect to said plane being assured with respect to the cathode and anode portions by the current leads to which they are welded, these current leads serving as stiffeners and resulting in the planarity of these electrode portions and their parallelism with respect to the reference plane formed by the bimetallic base plate. These electrodes are highly efficient in the electrolysis of alkaline chlorides.
