It is disclosed an electrolytic cell including one anode module having a plurality of anodes (preferably oxygen-evolving anodes); one cathode module, opposing the anode module, having a plurality of vertical cathodes, wherein each of the anodes and cathodes being vertically oriented and spaced one from another; a cell reservoir; and a cell bottom supporting the cathode module. The cell bottom comprises upper surfaces and a channel, with the vertical cathodes extending upward from the upper surfaces. The upper surfaces are configured to direct via gravity substantially all of the liquid aluminum produced in the electrolytic cell to the channel, and the channel is configured to receive liquid aluminum from the upper surfaces. The liquid aluminum produced at the outer surfaces of the cathodes flows via gravity therefrom across the upper surfaces and into the channel, thereby creating a flowing layer of liquid aluminum over the upper surfaces.
