Abstract
Abstract An improved construction for electrolytic cells for the electrolysis of molten sodium chloride and similar salts is provided. the electrolytic cell is characterized in that the anode consists of horizontal slabs of graphite supported by the refractory wall of the bottom half of the cell structure and the anodes are submerged slightly in the electrolyte employed. Such a structure provides a stronger anode, and more rigidly positioned with respect to the bottom of the cell, than if the same were hanging from the top of the cell by stems or necks, as in conventional electrolytic cells.
