SOL-GEL DERIVED HIGH PERFORMANCE CATALYST THIN FILMS FOR SENSORS, OXYGEN SEPARATION DEVICES, AND SOLID OXIDE FUEL CELLS

摘要

A method of forming a sol-gel derived catalyst thin film on an electrolyte substrate includes forming a cathode precursor sol and/or composite cathode slurry, depositing the cathode precursor sol or slurry on the electrolyte and drying the deposited film to form a green film, and heating the green film to form a sol-gel derived catalyst thin film. An electrochemical cell such as a solid oxide fuel cell can include the sol-gel derived catalyst thin film.
