Abstract:

A method for the manufacture of an electrode for an energy storage or conversion device comprises thermally spraying a feedstock mixture comprising an effective quantity of a source of a thermally protective salt and an active material or active material precursor onto a substrate to produce a film of the active material and salt. The film can have a thickness of about 1 to about 1000 microns. In a particularly advantageous feature, the active materials which ordinarily decompose or are unavailable at the high temperatures used during thermal spray processes, such as metal chalcogenides such as pyrite, CoS, WS, Ni(OH), MnO, and the like may be thermally sprayed to form an electrode when the feedstock mixture employs an effective amount of a source of the thermally protective salt coating. The active material feedstock may comprise microstructured or nanostructured materials, which after thermal spray results in electrodes having microstructured or nanostructured active materials, respectively.

Abstract:

A solid oxide fuel cell comprises a dense electrolyte disposed between a porous anode and a porous cathode wherein the dense electrolyte comprises doped lanthanum gallate or yttria stabilized zirconia, the porous anode comprises yttrium-doped strontium titanate, yttrium-doped strontium titanate and nickel, lanthanum-doped ceria and nickel or yttria stabilized zirconia and nickel and the porous cathode comprises doped lanthanum ferrite or strontium-doped lanthanum manganite. The fuel cell may further comprise an interlayer(s) comprising lanthanum-doped ceria disposed between an electrode (anode, cathode or both) and the electrolyte. An interconnect layer comprising doped lanthanum chromate may be disposed between the anode of a first single fuel cell and the cathode of a second single fuel cell. The anode, cathode, electrolyte and optional interlayer(s) are produced by thermal spray.
