An improved electrolytic cell for magnesium chloride which essentially comprises: at least one pairs of anode and cathode arranged with a respective principal face thereof in a substantial verticality, at least one bipolar intermediate electrode placed in a row between the anode and cathode, an electrolytic chamber to contain such electrodes, and a metal collecting chamber which is attached to the electrolytic chamber but separated therefrom by a partition, characterized in that said intermediate electrodes essentially consists of a substantially flat graphite portion to provide an anodic face and an iron portion to provide a cathodic face, both materials being spaced from each other and jointed together with rods of iron, which are tightly secured to the graphite, to ensure an intimate electrical connection therebetween, and that a cavity thus formed between the two materials is arranged to fitly communicate at one end with a through hole in the partition to allow passage of electrolyte bath carrying magnesium metal product from the electrolytic chamber to the metal collecting chamber.
