Claims
- 1. A solid oxide fuel cell assembly, comprising:a substantially planar array of fuel cells on a substrate, each said cell comprising cathode, anode, electrolyte and electrode interconnect component structures, each said component structure of each said cell having a sub-planar arrangement of one said component structure to another; an oxidant cavity adjacent said substrate; and a fuel cavity adjacent said sub-planar anode arrangement.
- 2. The assembly of claim 1 wherein said anode comprises a composite having a catalytic metal and a ceria material, said metal present in an amount less than 60 weight percent of said anode.
- 3. The assembly of claim 2 wherein said metal is catalytic for the cracking of hydrocarbons.
- 4. The assembly of claim 3 wherein said metal is selected from the group consisting of Pt, Ru, Pd, Fe, CO and Ni.
- 5. The assembly of claim 4 wherein each said metal is present in an amount less than about 40 weight percent.
- 6. The assembly of claim 2 wherein said ceria material further includes a dopant.
- 7. The assembly of claim 2 wherein said anode is a nickel composite.
- 8. The assembly of claim 7 wherein said composite further includes zirconia.
- 9. The assembly of claim 2 wherein said zirconia is an electrolyte, said zirconia doped with yttria.
- 10. A solid oxide fuel cell composite comprising:a substantially planar electrically-insulating substrate; a plurality of cathode components on said substrate, each said cathode component spaced one from another; an electrolyte on and between each said cathode component; a plurality of anode components, each said anode component spaced one from another and corresponding in number to said plurality of cathode components; and an interconnect component contacting a portion of each said cathode component and a portion of each said corresponding anode component.
