Abstract

The substrate in an electrochemical cell is (i) a spinel-metal oxide ceramic which can be made from a mix of magnesia and alumina powders compacted and fired to form a spinel*-magnesia ceramic, where spinel* is the particular spinel, magnesia-alumina, or (ii) a zirconia ceramic, or (iii) a zirconia-alumina ceramic, which has the same coefficient of thermal expansion as the zirconia thick-film electrolyte/diffusion barrier.
