In still another embodiment the present invention comprises a seamless flat solid oxide fuel cell that comprises an anode layer , an electrolyte layer , and a cathode. The cathode contains a series of ellipsoidal annular spaces and the series of ellipsoidal annular spaces have an open end and a closed end. Ribs separate the ellipsoidal annular spaces and the closed end has exclusively rounded edges.
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 () 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 () 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 () is applied over the electrolyte.

Abstract:
A fuel cell generator including a housing defining a plurality of chambers including a generator chamber having first and second generator sections. A plurality of elongated fuel cells extend through the first and second generator sections. An oxidant supply supplies oxidant to at least one of the chambers within the housing in order to provide oxidant to one end of each of the fuel cells. A fuel distribution plenum extends transversely to the elongated fuel cells and is located between the first and second generator sections. The fuel distribution plenum distributes fuel to the first and second generator sections in opposing directions within the generator chamber.
