Abstract

A bipolar multiple electrolytic cell having an alkali-chlorine diaphragm cell for obtaining caustic solution, chlorine and hydrogen in which the titanium metal electrodes act on one side as the anode and on the other as the cathode, the anode side being coated with a metal or metal oxide for activation purposes, and the cathode side having a dense coating of metal alloy of nickel and elements of the Group III or V of the periodic system, which is applied chemically, preferably by employing the so-called "Kanigen" process.
