Abstract
A metal oxide thin film structure for a solid oxide fuel cell, prepared by a method comprising dispersing a metal oxide nanopowder in a metal oxide salt solution and subsequent coating of the resulting metal oxide powder dispersed sol and the metal oxide salt solution on a porous substrate, has excellent gas impermeability, excellent phase stability, and is devoid of cracks or pinholes.
