CERAMIC CATHODE MATERIAL AND PREPARATION METHOD OF THE SAME

摘要

A ceramic cathode material used in a fuel cell and a preparation method for the same are disclosed. The disclosed ceramic cathode material is prepared by a mix of lanthanum-based compound, cobalt-based compound, and copper-based compound in order to be used in intermediate/low temperature fuel cell. The ceramic cathode material may be represented in LaCoyCuxO3−δ with x ranging from 0.01 to 0.3 and y ranging from 0.7 to 0.99. The prepared ceramic cathode material may be associated with high electrical conductivity and reduced coefficient of thermal expansion when operating in the temperature range between 500 and 800 degrees Celsius.
