Abstract
Abstract An electrode is provided for use in electrolytic cells employing metal electrodes. The electrode comprises two electrode surfaces positioned in parallel and having a space between them: and at least two conductive supports one conductive support separately attached to each electrode surface and positioned in the space between the electrode surfaces. The conductive supports are also attached to and are substantially perpendicular to an electrode plate.
