Abstract
An electrolysis cell, particularly for the production of aluminum, contains a cathode, a layer of liquid aluminum arranged on the upper side of the cathode, a melt layer thereon and an anode on the top of the melt layer. The cathode is composed of at least two cathode blocks, wherein at least one of the at least two cathode blocks differs from at least one of the other cathode blocks with regard to the average compressive strength, the average thermal conductivity, the average specific electrical resistivity and/or the apparent density.
