Sulfur tolerant composite cermet electrodes for solid oxide electrochemical cells

Abstract From the Canadian patent

An electrochemical apparatus is made containing an exterior electrode bonded to the exterior of a tubular solid, oxygen ion conducting electrolyte where the electrolyte is also in contact with an interior electrode said, exterior electrode comprising particles of an electronic conductor contacting the electrolyte, where a ceramic metal oxide coating partially surrounds the particles and is bonded to the electrolyte, and where a coating of an ionic-electronic conductive material is attached to the ceramic metal oxide coating and to the exposed portions of the particles.
