An aluminium smelting cell comprising a floor defining a cathode surface (4) which is substantially horizontal in the longitudinal direction of an overlying anode (1), shaped structures (2, 3) projecting from the cathode surface (4) and having exposed surfaces of aluminium wetted material; the shaped structures being positioned to cause preferential contouring of the anode (1), particularly at its longitudinal edges (5, 6) to allow for improved bubble release and to minimize cell resistivity.
Cellule de fusion d'aluminum comprenant un plancher déterminant une surface de cathode (4) qui est essentiellement horizontale selon la direction longitudinale d'une anode en surplomb (1), des structures formées (2, 3) placées en saillie sur la surface de cathode (4) et possédant des surfaces de matériau mouillé d'aluminium, les structures formées étant positionnées de façon à provoquer un contournage préférentiel de l'anode (1), en particulier, à ses extrémités longitudinales (5, 6), permettant ainsi une libération de bulles plus efficace et une minimization de la résistivité de la cellule.
