(JP8507896-W)      Tube is made of ZrO2:Y2O3. The inner electrode is pref. a spiral wire (4) in contact with porous layer of conductive ink; and the outer electrode is pref. a spiral wire (5) in contact with a porous layer of doped a manganite.    Fuel cell system incorporating a number of the above tubular SOFC structures is claimed.    Gas tight planar interconnect (40, 41) for a planar SOFC comprises a ceramic sheet with conductive ceramic bodies (42) extending through it to provide conductive paths.    Stacked SOFC structure comprises sub-assemblies of anode, electrolyte plate and cathode with passageways between adjacent sub-assemblies for fuel gas and air; and fuel gas supply conduits extending between adjacent sub-assemblies to deliver fuel gas to central regions of each anode such that delivered gas flows outwards from the central regions of the anode towards the stack edges.    USE/ADVANTAGE -   The structures are capable of rapid temp. change without cracking and are simple to seal.    (US5827620-A)      Tube is made of ZrO2:Y2O3.
