Abstract
Aluminum smelter comprising: (i) a series of electrolytic cells, comprising an anode, a cathode and a pot shell equipped with a side wall and a bottom, each cathode including at least one cathode output, (ii) a main electric circuit through which an electrolysis current passes, including an electrical conductor connected to each cathode output of a cell N, and to the anode of a cell N+1, and (iii) a means to stabilize the electrolytic cells. At least one of the cathode outputs of the cathode of N passes through the bottom of the pot shell, and during the operation of N and N+1, the electrolysis current passes, in an upstream-downstream direction only, through each electrical conductor extending from each cathode output of N in the direction of N+1.
