ABSTRACT:
The invention relates to a diaphragm electrolytic cell, for the production of chlorine and caustic soda having superimposed modules, and a method for increasing the electrodic surface of a diaphragm electrolytic cell constituted by a module of interdigitated anodes and cathodes which foresees an additional cell module having the same geometry as that of the original cell. The additional module is hydraulically connected in series and electrically connected in parallel to the existing module.
