Fuel cell generator containing self-supporting high gas flow solid oxide

Abstract

An axially elongated, electrochemical cell assembly is made, containing a plurality of cell elements each made up of an electronically conductive, porous, inner electrode, an annular, solid electrolyte contacting and surrounding said first electrode, and an annular, electronically conductive, porous, outer electrode contacting and surrounding said electrolyte, with annular, electronically conductive, interconnection members disposed between and bonded to cell elements, where the inner electrodes of the cell elements are electronically connected through the interconnection member, and the outer electrodes of the cell elements are physically and electronically segmented from each other; where a plurality of such cell assemblies can be connected by a sleeving means and placed in the generating chamber of an electrochemical cell generator, which also has an associated dual gaseous reactant input, at least one combustion product chamber, and a combustion product gas exhaust.
