Very low energy consumption cell designs: The cell heat balance challenge

Abstract

At last year TMS, the author presented the electrical design of a cell operating at 500 kA, 0.8 A/cm2 of anode current density and 3.2 cm ACD. This cell is predicted to have an energy consumption of about 11.2 kWh/kg. That cell would only dissipate 700 kW while a cell design of the same “platform” was previously designed to operate at 600 kA and 13.26 kWh/kg comfortably dissipating 1140 kW. Reducing the cell heat dissipation by about 40% is presenting a tremendous cell lining design challenge. This paper is describing it and is trying to address it.
