| 摘要 |
The present invention relates to an electrolysis cell, in particular for the production of aluminium, comprising a cathode, a layer of liquid aluminium on the top side of the cathode, a melt layer on top of said layer of liquid aluminium, and an anode above the melt layer, wherein the cathode has, on the top side thereof, a surface profiling formed from two or more elevations, wherein the surface profiling of the cathode is configured and arranged such that in each case one elevation is provided at at least two of the twenty points on the surface of the top side of the cathode which are arranged in each case vertically below those regions of the boundary between the layer of liquid aluminium and the melt layer at which the peaks with the twenty highest maximum values are present in the reference wave forming potential distribution at the boundary, wherein a reference wave forming potential is defined as the wave forming potential which is present at a point in the boundary between the layer of liquid aluminium and the melt layer during the operation of the electrolysis cell with - instead of the cathode with surface profiling - a reference cathode without surface profiling but of otherwise identical configuration to the cathode with surface profiling. |
