Method of making a unitary electric current transmission element for monopolar or bipolar filter press-type electrochemical cell units.

摘要

A method for making and assembling either a monopolar or bipolar filter press-type electrochemical cell unit employing an electric current transmission element. The transmission element is an integrally formed, unitary, cast structural element positioned between the peripheral boundaries for adjacent electrolyte compartments of two cells located on opposite sides of the transmission element. The transmission element comprises a planar support portion (114) having anode and or cathode bosses (118) extending outwardly from opposite sides of the support portion. The bosses not only serve as a mechanical support for respective flat plate anode and or cathode components but also they serve as stand-off means and electrical current collectors and dispersers from the electrode component of one cell to the electrode component of the next cell. Simplicity of design coupled with incorporation of many functional elements into a single and unitary part eliminates warpage problems, inherent high voltage problems and membrane "hot spot" problems. The transmission element may optionally be provided with protective metal side liners (186) and electrical leads (190) to the cell units which allows the transmission element to be employed in a monopolar or bipolar cell series.
