Abstract
An electrolytic cell is suitable for production of aluminium, and includes at least one collector bar made of first metal and at least one complementary bar 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 so that the external end of the complementary bar is at a specified distance from a specified end face of the block. The second end terminates so as to limit heat losses from said cell. The cell makes it possible to obtain significantly lower voltage drops while avoiding excessive heat losses through the collector bars.
