An electrolysis cell for the production of aluminum has a liquid aluminum layer on a cathode, a melt layer on the liquid aluminum, and an anode above the melt layer. An upper side of the cathode has surface profiling with two or more elevations provided at at least two of the twenty points of the surface of the upper side of the cathode vertically beneath those regions of the boundary surface between the layer of liquid aluminum and the melt layer in which peaks with the twenty highest maxima are present in the distribution of a reference wave formation potential in the boundary surface. The reference wave formation potential is defined as the wave formation potential which, when the electrolysis cell is operated with a reference cathode without surface profiling is present at a point in the boundary surface between the layer of liquid aluminum and the melt layer. |
