Abstract
Abstract An electrode assembly is provided for use in electrolytic cells employing metal electrodes. The electrode assembly utilizes an electrode plate, an electrically-conductive surface and a conductive support having a first section attached to and substantially perpendicular to the electrode plate; and a second section substantially parallel to the electrode plate and attached to the first section and to the electrically-conductive surface. The electrode assembly is employed in electrolytic cells for producing chlorine and caustic soda or oxychlorine compounds by the electrolysis of alkali metal chloride solutions.
