Patent ID: 7033479

Claim:
A method for substituting an electrode of an electrolytic cell having at least one renewable electrode structure comprising: at least one back-wall provided with a support element made of projections delimited on the side opposite to the back-wall by a terminal surface, said terminal surfaces of said projections lying on the same plane at least one electrode in contact with said terminal surfaces of said projections, thereby defining a contact surface wherein a substantial portion of said contact surface is free from constraints and the at least one electrode is fixed to each of said terminal surfaces of said projections only in at least one peripheral region of said terminal surfaces with a substitute electrode, comprising removing said electrode to be replaced by cutting a portion of said terminal surface of said projections, wherein said cutting causes the removal of said peripheral region of said terminal surface of said projections fixed to said electrode, while avoiding the removal of at least a substantial residual portion of said terminal surface free from constraints, then placing a substitute electrode on said residual portion of said terminal surface of said projections by fixing said substitute electrode to said residual terminal surface of said at least one projection only in at least one peripheral region of said terminal surface.
