Abstract (en)

[origin: CA2838940A1] The invention relates to an electrolytic cell, especially for producing aluminum, which comprises a cathode, a liquid aluminum layer arranged on the top surface of the cathode, a melt layer on top thereof and an anode on top of said melt layer, the cathode having at least one opening that extends vertically through the cathode, through which opening at least one current supply extends vertically and is electrically connected to the anode and/or the cathode. The electrolytic cell comprises at least one further current supply outside the opening o the cathode, which current supply extends vertically at least in sections and is electrically connected to the cathode and/or the anode. The invention further relates to a cathode for an electrolytic cell.
