ABSTRACT:
A cell for producing a metal by electrolysis of an anhydrous metal halide in a bath of molten salts comprises an external jacket of substantially parallelipipedal shape, having cooling means, ports for the input and output of liquid and gaseous fluids and means for supplying electricity, the lower end of the jacket includes a receptacle zone to collect the metal produced; a plurality of stacked electrodes in the central portion of the cell, each stack comprising, in a vertical direction and in descending order, a current supply electrode, intermediate multipolar members and a current output electrode, defining regular interpolar spaces; and a gas collecting zone in the top portion. The cell is characterized in that the multipolar members are assembled in a vertical stack, and the interpolar spaces are substantially vertical. The cell is particularly well adapted for the production of aluminum by electrolysis of the corresponding chloride.
