High power density seal-less tubular solid oxide fuel cell by means of a wide interconnection
The present invention is a solid oxide fuel cell that includes at least one flat support tube having a first side, a second side, and an outer surface and at least one interconnection ( 3 ) deposited to the full surface of the outer surface of at least one side of the tube. At least one support tube comprises a solid electrolyte layer ( 4 ) that is deposited over an outer surface of the support tube. At least a portion of the interconnect is covered with electrolyte and at least one anode ( 5 ) is applied over the electrolyte.
1 . A solid oxide fuel cell comprising:
at least one flat support tube having a first side, a second side, and an outer surface; and
at least one interconnection electrically deposited to the full surface of the outer surface of one side of the tube;
wherein the at least one support tube comprises a solid electrolyte layer that is deposited over an outer surface of the support tube;
wherein at least one anode is applied over the electrolyte.
2 . The fuel cell of claim 1 wherein an oxidant is introduced to the support tube by an air feed tube.
3 . The fuel cell of claim 1 wherein the anode is made of at least one of Ni felts, Ni screen and combinations thereof.
4 . The fuel cell of claim 1 wherein the masking material is a metal.
5 . The fuel cell of claim 1 wherein the masking material is nickel.
6 . The fuel cell of claim 1 further comprising ribs adapted to conduct electricity.
7 . A solid oxide fuel cell comprising:
at least one flat support tube having a first side, a second side, and an outer surface;
ribs adapted to conduct electricity; and
at least one interconnection deposited to at least a majority of the surface of the outer surface of one side of the tube;
wherein the at least one support tube comprises a solid electrolyte layer that is deposited over an outer surface of the support tube; and
wherein at least one anode is applied over the electrolyte.
8 . The fuel cell of claim 6 further comprising a means for introducing an oxidant to the support tube.
9 . The fuel cell of claim 8 wherein the means for introducing an oxidant to the support tube is an air feed tube.
10 . The fuel cell of claim 7 wherein the anode is made of Ni felts, Ni screen or Ni screen and Ni foam combination.
11 . The fuel cell of claim 7 wherein the masking material is a metal.
