ABSTRACT:
A bipolar electrolytic cell comprises a plurality of side-by-side cell units, each unit having parallel anode and cathode plates spaced by a centerboard and electrically connected by a bipolar connection comprising a plurality of copper rods extending through the centerboard and shielded at their opposite ends from electrolyte in the cell by protective covers projection welded to opposite sides of the centerboard. The cover for one end of each rod comprises a cup having the base of its opening shaped to conform closely to the one end and frictionally welded thereto.
A plurality of similar spacer and ring assemblies are arranged over opposite sides of the centerboard. Each assembly comprises a spacer projection welded to an associated side of the centerboard and to the inner periphery of a ring extending around the spacer. The spacers at one side of the centerboard may comprise the protective covers at said one side. The outer peripheries of the rings of adjacent assemblies are projection welded to opposite ends of plate supporting units having plate supporting edges projection welded to the anode or cathode plate confronting said associated side. The rings and ribs are located at preselected adjusted positions with respect to the spacers, such that the plates welded to the ribs are supported in predetermined planes assuring the desired minimum parallel spacing between the anode and cathode plates of adjacent cell units.
