Abstract
Abstract ABSTRACT An electrode assembly is provided for use in elec-trolytic cells employing metal electrodes. The electrode comprises two electrode surfaces, positioned in parallel and having a space between them, and at least one conductive support having one end attached substantially perpendicular to the electrode support plate and having a section attached along a side of the electrode surface. This section has a portion having a curvature from about 2 to about 30 degrees from an axis substantially perpendicular to the electrode support plate. The electrode assembly is employed in electrolytic cells for producing chlorine and caustic soda or oxychlorine compounds by the electrolysis of alkali metal chloride sol-utions.
