Beschreibung
Zusammenfassung:	The invention concerns a diaphragm chlor-alkali electrolysis cell comprising a cover, a conductive base for supporting the anodes and a cathode in the form of a box provided with internal wall, external wall and tubular fingers made of a mesh or perforated sheet covered with a porous diaphragm. One or more copper sheets (4) for electric current distribution are fixed to the cathode external walls (1). The connection between the copper sheets and the cathode external walls is made by means of bolts (3) with the interposition of a conductive and deformable element (12) provided with residual elasticity under compression. The weldings for the assembling of the cathode walls are free from internal stresses.
