Abstract

The present invention concerns a method of retrofitting of a membrane electrolysis cell, wherein a rigid cathode is shaped by plastic deformation of the regions in correspondence of cathodic supports; a pre-shaped conductive elastic element having compressed regions in correspondence of said cathodic supports is overlaid onto said rigid cathode; a flexible planar cathode provided with a catalytic coating is overlaid onto said conductive elastic element. The invention also concerns a correspondingly retrofitted electrolysis cell.
