Title: Electrode and method of interconnection sintering on an electrode of an electrochemical cell

Abstract

An electrode structure is made by applying a base layer of doped LaCrO[sub 3] particles on a portion of an electrode 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, after which solid oxide electrolyte can be applied to the remaining portion of the electrode and the electrolyte can be covered with a cermet exterior electrode. 2 figures.
