Aluminum electrolytic cell arrays and method of supplying electric power to the same

摘要

In an array of rectangular aluminum electrolytic cells, each cell is provided with a plurality of anode electrodes, a plurality of current collecting cathode bars parallel with shorter side walls and located at a bottom of the cell and a plurality of side cathode bus bars extending along longer side walls. The cathode bars are divided into a least two groups. The current flowing through respective groups is collected at their centers on the one side and current flowing through respective groups is collected at both ends thereof on the other side. The collected currents are supplied to the anode electrodes of a next cell.
