In a sidewall-enclosed electrolytic cell, such as for the electrolysis of brine to form chloralkali product, the cell can have at least one cathode sidewall. There is now provided an at least substantially wall-sized, planar busbar that is interface bonded to the cathode sidewall. The interface bonded, wall-sized busbar plus sidewall thereby at least substantially serve as a wall unit for the electrolytic cell. The wall-sized busbar has at least one internal passageway therethrough for the circulation of cooling fluid. Where the bonded busbar is connected by a jumper switch for current connection, the cooling passageway of the busbar may connect at the location of the jumper switch.

Bonded busbar for diaphragm cell cathode

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.
