An aluminum electrolysis cell comprises a cathode and a continuous anode disposed above the cathode. The anode is composed of carbon elements which are glued or in some other way connected to one another. Onto the anode, there are added new elements to replace carbon material consumed during the electrolysis process. The anode is divided into sections defined by easily detachable holders or cassettes which are disposed close to one another in a row longitudinally of the cell. The cassettes are each provided at their upper ends with projections designed to be detachably connected to bearer walls or structures along the long sides of the cell.
