Abstract: In one embodiment, an electrochemical cell stack comprises at least two electrochemical cells, wherein each electrochemical cell comprises a hollow elongated electrolyte, having disposed upon it an anode and a cathode, and further wherein with the exception of the outermost cell, each electrochemical cell is placed within another electrochemical cell in a manner such that at least one of the surfaces of the respective electrochemical cells are approximately parallel to one another.

Abstract: A method of manufacturing a green electrolyte tube comprises forming a composition comprising lanthanum-strontium-gallium-magnesium oxide powder, a binder, a lubricant, a solvent and a pH control agent into a green electrolyte tube, wherein the outer diameter of the green electrolyte tube has a tolerance of less than or equal to about ±0.3 millimeters over a tube length of greater than or equal to about 5 millimeters, and the wall thickness of the green electrolyte tube has a tolerance of less than or equal to about ±0.2 millimeters over a length of greater than or equal to about 5 millimeters.

Abstract: A disclosed apparatus for generating electrical power has, according to one embodiment of the invention, a plurality of tubular solid oxide fuel cells contained in a reaction chamber. The fuel cells are secured at one end thereof in a manifold block, the other ends thereof passing freely through apertures in a baffle plate to reside in a combustion chamber. Reaction gases are supplied to the insides of the tubular fuel cells from a plenum chamber below the manifold block and to the reaction chamber surrounding the outsides of the fuel cells through an annular inlet path, which may include a reformation catalyst. The gases inlet path to the plenum chamber, and the annular inlet path surround the reaction chamber, are both in heat conductive relation with the reaction chamber and the combustion chamber, and raise the gases to formation and reaction temperatures as appropriate.
