A segmented-in-series high temperature solid-state electro-chemical device in which the cell segments are supported on a substrate comprising a porous metal layer for mechanical strength and a non-conducting porous layer for electrical insulation between cell segments is fabricated by co-sintering at least the metal substrate, insulating layer, an electrode and electrolyte. This allows for efficient manufacturing and the use of a thinner electrolyte (e.g., less than 40 microns thick) than in conventional designs, with a resulting performance improvement attributable at least in part to increased ionic conductivity. Alternative structures for the cell and interconnect repeat segments which are supported on a metallic substrate, as well as methods for producing said structures, specific compositions of the interconnect, and Al-containing compositions for the metallic substrate are described.
