Abstract

A cell for the electrowinning of aluminium from alumina dissolved in a fluoride-containing molten electrolyte (30) , comprises a non-carbon metal-based anode (10 ) having an electrically conductive metallic structure (11,12,13) . This anode structure comprises an outer part with an electrochemically active anode surface (16) on which, during electrolysis, oxygen is anodically evolved, and which is suspended in the electrolyte substantially parallel to a facing cathode (20, 22, 35) . The anode structure has one or more flow- through openings (17) extending from the active anode surface through the metallic structure, the flow-through opening (s) being arranged for guiding a circulation of electrolyte driven by the fast escape of anodically evolved oxygen. The outer part of the anode comprises a layer that contains predominantly cobalt oxide CoO to enhance the stability of the anode.
