Abstract

An electrolyzer for the production of chlorine from an aqueous alkaline halide solution includes a plurality of electrolysis cells each having a housing of two half-shells. The bottom side of each of the half-shells is in a plane parallel to a plane of an adjacent anode or cathode, the space between the bottom side and the anode or the cathode being provided with framework-pattern metallic reinforcements. Each bottom side has one or more contact strips attached to its outer surface which are arranged in a congruent position to the contact strips on the bottom side of the adjacent electrolysis cell, and extend over the length or width of the cell. The contact strips are aligned with and connected by electrically conducting means to part of the framework-pattern reinforcements and the unperforated sections of the adjacent anode or cathode. The two half-shells and a membrane partition wall are assembled to form an electrolysis cell sealed by two gaskets.
