CERAMIC CATHODE MATERIAL OF SOLID OXIDE FUEL CELL AND MANUFACTURING METHOD THEREOF

摘要

A ceramic cathode material of a solid oxide fuel cell and a manufacturing method thereof are disclosed. The method includes mixing a lanthanum-containing compound, a cobalt-containing compound, a nickel-containing compound, and a copper-containing compound, for preparing the ceramic cathode material of the solid oxide fuel cell of intermediate/low type. The ceramic cathode material of the solid oxide fuel cell is LaCo_zNi_yCu_xO_3−δ. X ranges from 0.01 to 0.3, y ranges from 0 to 0.89, and z ranges from 0.1 to 0.99. The ceramic cathode material manufactured by mixing the lanthanum-containing compound, the cobalt-containing compound, the nickel-containing compound, and the copper-containing compound when operating within the temperature range from 500 to 800 degrees Celsius is of high electrical conductivity and reduced thermal expansion coefficient.
