STABLE HIGH CONDUCTIVITY FUNCTIONALLY GRADIENT COMPOSITIONALLY LAYERED SOLID STATE ELECTROLYTES AND MEMBRANES

摘要

Stable high conductivity functionally gradient compositionally layered solid bodies suitable for use as electrolytes and membranes and providing improved oxygen-ion conductivity for electrolytes and improved mixed oxygen-ion and electronic conductivity for membranes. The electrolytes provide solid oxide fuel cells with high efficiency operation at 300 DEG to 800 DEG C.
