Title:

ELECTROLYSIS CELL FOR THE PRODUCTION OF ALUMINIUM COMPRISING MEANS TO REDUCE THE VOLTAGE DROP

Document Type and Number:

WIPO Patent Application WO/2008/062318

Kind Code:

A3

Abstract:

The invention relates to an electrolytic cell (1) intended for production of aluminium including at least one collector bar (6) made of first metal and at least one complementary bar (20, 20') made of a second metal having an electrical conductivity greater than the first metal and arranged adjacent to one of the side faces of the collector bar (6) so that the external end (202, 202') of the complementary bar (20, 20') is at a specified distance A, A' from a specified end face (51, 51') of the block (5). The second end (202, 202') preferably terminates so as to limit heat losses from said cell (1). The invention makes it possible to obtain significantly lower voltage drops than known cells while avoiding excessive heat losses through the collector bars.
