ABSTRACT:
Disclosed is a method for electrically and mechanically connecting the backplates of a bipolar electrode to be used in a filter press electrolytic cell for electrochemical production. This method employs the use of a metal laminate strip having surfaces of metallic substances identical and corresponding to the metallic makeup of the given backplates which can be welded between the anode and cathode backplates using standard weldment procedures. The metal laminate strips are placed in a spaced series such that the anode and cathode backplates present two parallel planes in spaced relation to each other thereby leaving a space for the escape of hydrogen gas, preventing hydrogen embrittlement of the titanium anode backplate.
