Abstract

An exchangeable solid cathode such that its average density is less than that of the molten aluminum, as a result of which the said cathode floats projecting into the electrolyte from below. At least three vertical, electrically insulating spacers are attached to the work face of the cathode and, due to the upthrust on the floating cathode, press against the work face of the related anode. The said floating cathode also features stabilizing positioning facilities at the side which insure proper lateral positioning of the cathode.
