A solid oxide fuel cell stack 10 comprises a first solid oxide fuel cell 12, a second solid oxide fuel cell 14, an interconnect 16, and a joining member 18. The first solid oxide fuel cell 12 includes a cathode 32. The second solid oxide fuel cell 14 includes an anode 36. The interconnect 16 is positioned between the cathode 32 of the first solid oxide fuel cell 12 and the anode 36 of the second solid oxide fuel cell 14. The joining member 18 joins the interconnect 16 to the cathode 32 of the first solid oxide fuel cell 12 and/or the anode 36 of the second solid oxide fuel cell 14, wherein the joining member 18 comprises a porous substrate 42, 43. The porous substrate may be formed by impregnating reticulated foam with ceramic slurry and firing. It may have a conductive coating of doped lanthanum cobaltite, lanthanum manganite, praseodymium cobaltite or manganite or other doped conductive oxides or metals. |
