Abstract

The present invention relates to an electrolytic cell, particularly designed for obtaining caustic soda (NaOH) and halogens by electrolysis, provided with at least one first electric terminal and at least one second electric terminal positioned adjacent each other for carrying out the electrolysis, characterized in that the first electric terminal is an anode, centrally positioned in the electrolytic cell, constituting an anodic chamber (20) and the second electric terminal comprises two cathodes, each positioned laterally respective to the anode and opposite each other and constituting a respective cahodic chamber (30), the anode and each cathode being separated by means of at least one semi-permeable membrane (4).
