Abstract: Disclosed is a spring-loaded electrolytic cell bank of modular construction in which a unitary anode and cathode cell is sandwiched with an identical cell and a multicontact, strip form conductor is interposed therebetween. The conductor establishes electrical connection betwen an anode of one cell and a cathode of the adjacent cell forming a bipolar series connection. The multi-contact conductive strips may be in the form of flat bars having louvers therein, an undulate strip or an askew helix which will contact the adjacent cell units at a plurality of contact points. The cell units and conductive strips are alternated in a filter press type cell bank for electrolytic processes such as the production of chlorine and caustic from the electrolysis of an aqueous brine.
