Summary:A solid oxide fuel cell (SOFC) manifold and interconnect structure 20 includes a manifold that has a dense and hermetic planar surface 21 that is impervious to fuel gas used with the corresponding SOFC. A porous material 22 includes a permeable planar surface 23 that is in lateral contact with the planar surface 21 of the manifold to form an electrode interconnect. The exposed surface of the junction 44 between the dense and hermetic planar surface 21 and the permeable planar surface 22 is substantially flat and devoid of discontinuities, corners and seams. The dense and hermetic planar surface 21, the permeable planar surface 22 and the exposed surface of the junction lay in a single common plane suitable for thermal deposition of electrode and electrolyte layers 19.
