Low sintering lanthanum ferrite materials for use as solid oxide fuel cell cathodes and oxygen reduction electrodes and other electrochemical devices

摘要

The present invention provides novel compositions that find advantageous use in making electrodes for electrochemical cells. Also provided are electrochemical devices that include active oxygen reduction electrodes, such as solid oxide fuel cells, sensors, pumps and the like. The compositions comprise a modified lanthanum ferrite perovskite material. The invention also provides novel methods for making and using the electrode compositions and solid oxide fuel cells and solid oxide fuel cell assemblies having cathodes comprising the compositions.
