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.
Claims9
A solid oxide cell, comprising:
- an inner tubular electrode having an outer surface;
- an outer electrode;
- and
- a metal oxide electrolyte adapted to provide ionic conductivity between the inner tubular electrode and the outer electrode;
- wherein the metal oxide electrolyte comprises a plurality of thin sheets oriented substantially perpendicular to the outer surface of the inner tubular electrode, and a metal oxide contacting the thin sheets;
- wherein the thin sheets are mica.
