First claim

Opening claim text (preview).

What is claimed is: 1. A composite anode for a hydrocarbon solid oxide fuel cell, the anode comprising a layered perovskite ceramic and a bi-metallic alloy, wherein the layered perovskite comprises Pr 0.8 Sr 1.2 (Co,Fe) 0.8 Nb 0.2 O 4 . 2. The anode of claim 1 , wherein the bi-metallic alloy comprises Co—Fe. 3. The anode of claim 1 , wherein the anode is configured to be oxidized and comprise a cubic perovskite. 4. The anode of claim 1 , wherein the layered perovskite ceramic has a lattice spacing of less than 0.5 nanometers. 5. The anode of claim 1 , wherein the layered perovskite ceramic has a lattice spacing of less than 0.3 nanometers. 6. A hydrocarbon solid oxide fuel cell comprising: an anode, the anode comprising layered perovskite ceramic and a bi-metallic alloy, wherein the anode comprises Pr 0.8 Sr 1.2 (Co,Fe) 0.8 Nb 0.2 O 4 ; a cathode; and an electrolyte. 7. The fuel cell of claim 6 , wherein the bi-metallic alloy comprise Co—Fe. 8. The fuel cell of claim 6 , wherein the cathode comprises Ba 0.9 Co 0.7 Fe 0.2 Nb 0.1 O 3 . 9. The fuel cell of claim 6 , wherein the electrolyte comprises La 0.8 Sr 0.2 Ga 0.83 Mg 0.17 O 3 . 10. The fuel cell of claim 6 , wherein the cathode comprises Ba 0.9 Co 0.7 Fe 0.2 Nb 0.1 O 3 and the electrolyte comprises La 0.8 Sr 0.2 Ga 0.83 Mg 0.17 O 3 . 11. A method of forming a composite anode for a hydrocarbon solid oxide fuel cell, the method comprising: printing electrode ink on an electrolyte surface, the electrode ink comprising a layered perovskite ceramic and a bi-metallic alloy, wherein the layered perovskite comprises Pr 0.8 Sr 1.2 (Co,Fe) 0.8 Nb 0.2 O 4 . 12. The method of claim 11 , wherein the bi-metallic alloy comprise Co—Fe. 13. The method of claim 11 , further comprising oxidizing the anode to form a cubic perovskite.
