ABSTRACT:
A generic, simple, economical method for making and assembling either a monopolar or bipolar filter press type electrochemical cell unit. The first feature is making a novel central cell element. This cell element is an integrally formed, unitary, cast structural element for filter press electrolysis cell which incorporates into a single cell unit the central barrier between the peripheral boundaries for the adjacent anolyte compartment and adjacent catholyte compartment of two electrolysis cells located on opposite sides of the central barrier. Also incorporated into the single cast structural element are anode bosses and cathode bosses extending outwardly from opposite sides of the central barrier. These bosses not only serve as mechanical support for their respective flat plate anode and cathode elements, but also they serve as stand-off means and electrical current collectors and dispersers from the cathode of one electrolysis cell to the anode of the next cell. Simplicity of design coupled with incorporation of many functional elements into one part eliminates many cell warpage problems, inherent high voltage problems and membrane "hot spot" problems. The second step in the method is the attachment of protective metal liner pans to the sides of the central cell element.
