Abstract
A cell for the production of aluminium by the electrolysis of an aluminium compound dissolved in a molten electrolyte, in which an outer mechanical structure forming an outer shell ( ) houses therein one or more inner electrically-conductive cathode holder shells or plates ( ) which contain a cathode mass ( ) and is/are connected electrically to the busbar. The cathode mass ( ) has an aluminium-wettable top surface ( ), preferably at a slope forming a drained cathode. The inner cathode holder shell or shells ( ) is/are separated from the outer shell ( ) by an electric and thermic insulation ( ), the cathode holder shell(s) ( ) also serving to distribute current uniformly to the cathode mass ( ). The or each cathode ( ) formed by the cathode holder shell ( ) and cathode mass ( ) is removable from the cell as a unit.
