Title: Cellule bipolaire a cathodes au carbone servant a la production d'aluminium
Inventor: DURUZ JEAN-JACQUES
IPC: C25C3/06
Filed: 1999-08-17
Abstract: Cette cellule bipolaire pour extraction électrolytique d'aluminium est pourvue d'électrodes bipolaires constituées, chacune, d'un corps de cathode au carbone dont un coté porte une surface active sur laquelle est produit l'aluminium et dont l'autre est rattaché, par le biais d'une couche barrière imperméable à l'oxygène, à une couche anodique électrochimiquement active dont la surface extérieure à base d'oxyde de fer dégage de l'oxygène. Cette couche anodique peut comporter un substrat anodique à base de métal et une couche extérieure à base d'un oxyde de métal de transition, de l'oxyde de fer notamment, cette couche étant, soit déposée, soit obtenue par oxydation de la surface du substrat anodique contenant du fer. En cours d'utilisation, il est possible de conserver à la couche anodique ses dimensions à condition de maintenir dans l'électrolyte une certaine concentration en espèces de métal de transition présentes dans la couche électrochimiquement active sous forme d'un ou de plusieurs oxydes de métaux de transition correspondants. La température de fonctionnement de la cellule est suffisamment basse pour que la concentration nécessaire en espèces de métal de transition soit limitée du fait de leur solubilité réduite dans l'électrolyte à ladite température de fonctionnement. De ce fait, la contamination de l'aluminium par les espèces de métal de transition reste à un niveau admissible.
