ABSTRACT:
An electrolyzer for producing an aqueous alkali hydroxide solution, halogen, and hydrogen from an aqueous halogenide-bearing electrolyte. The electrolyzer includes a plurality of alternating anolyte and catholyte chambers each formed by a pair of anode plates and cathode plates, respectively. Seals are provided between and around the perimeter of the two anode and cathode plates to define the chambers. A flat membrane member, permeable to ions is disposed between adjacent anode and cathode plates. The anode and cathode plate and seals include passages for the flow of process fluids. Each anode and cathode plate comprises an active portion permeable to the flow of gas and liquid and an inactive portion impermeable to the flow of gas and liquid.
