Abstract: A cell for producing metal by electrolysis of aqueous solutions of the relevant chloride comprises at least one electrolytic tank having upright cathodes and upright insoluble anodes alternating in the longitudinal direction of the tank, each anode being surrounded by an anodic box whose sides which face cathodes each comprise a diaphragm, the cell further comprising means of collecting and recovering the chlorine released during electrolysis, means of drawing off vapor generated at the surface of the electrolyte, means of blowing gas into the bottom of the tank below each cathode, and rack-mounted U-shaped guide-rail locating means for use in placing and for retaining in position the cathodes, the anodes and the anodic boxes.
