OPTIMIZED CELL CONFIGURATIONS FOR STABLE LSCF-BASED SOLID OXIDE FUEL CELLS

摘要

Lanthanum strontium cobalt iron oxides (La(1-x )SrxCoyFe1-yO3-; (LSCF) have excellent power density (>500 mW/cm2 at 750°C). When covered with a metallization layer, LSCF cathodes have demonstrated increased durability and stability. Other modifications, such as the thickening of the cathode, the preparation of the device by utilizing a firing temperature in a designated range, and the use of a pore former paste having designated characteristics and combinations of these features provide a device with enhanced capabilities.
