In the method of controlling an aluminum reduction cell with prebaked anodes an area of reduced alumina concentration is defined in the cell by measuring the present electrical current values in at least one anode of the cell independently of other anodes. Upon detection of the electric current reduction in this anode, the rate of alumina feeding is increased into a bath of the cell at the area of reduced alumina concentration.
