Title: Low temperature electrolytes for solid oxide cells having high ionic conductivity

Abstract

Methods for forming a metal oxide electrolyte improve ionic conductivity. Some of those methods involve applying a first metal compound to a substrate, converting that metal compound to a metal oxide, applying a different metal compound to the metal oxide, and converting the different metal compound to form a second metal oxide. Electrolytes so formed can be used in solid oxide fuel cells, electrolyzers, and sensors, among other applications.
