Abstract: A cell for fused-salt electrolysis for reducing alumina in the presence of cryolite to metallic aluminum. The cell includes an insulated tank having a carbon bottom, two rows of anode rods disposed on opposite sides of an anode carrier positioned in the longitudinal center plane, an exhaust gas-collecting duct extending at the longitudinal center between the two rows of anode and covers downwardly inclined from the outside of respective rows of anode rods to respective edges of the tank and provided at the outer longitudinal edge and the transverse edges with a skirt that extends to the respective edge of the tank. Each cover is hinged adjacent to its longitudinal edge adjacent to the anodes and at least at its corner portions to a support which extends along the row of anode rods. A carrying arm is secured to each end portion of the support and is pivoted at its other end to the anode carrier.
