Abstract

La présente invention concerne une cellule pour l'électro-obtention d'aluminium comportant une base cathodique au carbone horizontale (11) présentant un revêtement de surface mouillable à l'aluminium (25) et une série de plaques (21) en matériau poreux réticulé mouillable à l'aluminium, tel que des mousses, remplies d'aluminium et disposé à plat sur le revêtement de surface mouillable à l'aluminium (25). Lors de son utilisation, la couche mince d'aluminium (22) mouille le revêtement de surface mouillable à l'aluminium (25) à la face supérieure de la base cathodique (11) et une partie inférieure des plaques poreuses remplies d'aluminium (21). Une couche supérieure d'aluminium (23) se forme au dessus des plaques poreuses remplies d'aluminium (21). La cellule peut fonctionner avec des anodes métalliques (10) éventuellement protégées par un revêtement d'oxyfluorure de cérium lors de son utilisation à une température supérieure à environ 910-930 ·C.
