Abstract

L'invention concerne un procédé et des améliorations apportés à une cellule d'électrolyse, ladite cellule comprend une cathode sensiblement horizontale (4) d'un matériau conducteur électronique ainsi que des fils conducteurs de courant tels que des barres collectrices électroniques intégrées. La cellule comprend également un système de barre omnibus. La cellule peut être activée lorsque l'on améliore la distribution de courant électrique, tandis que ladite cathode comprend au moins une sortie de courant sensiblement verticale (6).
