Abstract
A diaphragm cell cathode assembly has improved current distribution to a tube sheet distributing electrical current to cathode tubes. Electrical current is fed to the diaphragm cell assembly by grid bars connected to side plates. The current must then flow the side plates to the inner tube sheets, the tube sheets and side plates being generally in spaced apart, planar parallel relationship to one another. Assembly temperature uniformity, as well as temperature reduction, is now enhanced by providing supplemental distributor bars at the upper and lower regions of the grid bars, and in electrical connection between side plates and tube sheets.
