Abstract

An electrode structure (10) is made by applying a base layer of doped LaCrO.sub.3 particles on a portion of an electrode (16) and then coating the particles with a top layer composition such as CaO+Al.sub.2 O.sub.3, SrO+Al.sub.2 O.sub.3, or BaO+Al.sub.2 O.sub.3, and then heating the composition for a time effective to melt the composition and allow it to fill any open porosity in the base layer of doped LaCrO.sub.3 to form an interconnection (26), after which solid oxide electrolyte (18) can be applied to the remaining portion of the electrode (16) and the electrolyte (18) can be covered with a cermet exterior electrode (20).
