Abstract
An electrochemical cell for electrochemical reduction of a metal oxide in a solid state is disclosed. The cell includes a molten electrolyte (), an anode () formed from carbon in contact with the electrolyte, a cathode () formed at least in part from the metal oxide in contact with the electrolyte, and a membrane () that is permeable to oxygen anions and is impermeable to carbon in ionic and non-ionic forms positioned between the cathode and the anode to thereby prevent migration of carbon from the anode to the cathode. The membrane includes a body () and a lining () on the surface of the body on the cathode side of the membrane. The lining is formed from a material that is inert with respect to dissolved metal in the electrolyte and is impermeable to the dissolved metal. An electrochemical method based on the cell is also disclosed.
