Abstract
In one aspect, the present invention is directed to liquid anodes and fuels for production of metals from their oxides. In one aspect, the invention relates apparatuses for producing a metal from a metal oxide comprising a cathode in electrical contact with an electrolyte, a liquid metal anode separated from the cathode and the electrolyte by a solid oxygen ion conducting membrane, a fuel inlet, and a power supply for establishing a potential between the cathode and the anode. In another aspect, the invention relates to methods for production of metals from their oxides comprising providing a cathode in electrical contact with a molten electrolyte, providing a liquid metal anode separated from the cathode and the molten electrolyte by a solid oxygen ion conducting membrane, providing a fuel inlet, delivering a gaseous fuel comprising hydrogen to the liquid metal anode via the fuel inlet, and establishing a potential between the cathode and the anode.
