摘要： An aluminum electrolytic cell wherein, in a sealed type electrolytic cell having a raw material aluminum chloride feeding port and chlorine gas discharging ports in a top section and a molten metal reservoir in a bottom section and provided with an electrode element in the intermediate section so that a molten salt electrolytic bath containing aluminum chloride is electrolyzed in the cell and molten aluminum is collected from the metal reservoir in the bottom section, the electrode element is formed of funnel-shaped electrodes laminated at a fixed distance between the electrodes or a pair of right and left electrode plate groups opposed to each other at a fixed separation between them and inclined to be lower inward at least one intermediate bi-polar electrode is provided between both cathode and anode and a gas rising passage is formed between the outer edges of the funnel-shaped electrodes or the electrode plates and inner wall of the cell to prevent the rechlorination of the aluminum after electrolysis.
