Abstract
The present invention relates to composite material suitable for use as an electrode material in a solid oxide cell, said composite material consist of at least two non-miscible mixed ionic and electronic conductors. Further provided is a composite material suitable for use as an electrode material in a solid oxide cell, said composite material being based on (Gd1-xSrx)1-sFe1-yCoyO3-δ or (Ln1-xSrx)1-sFe1-yCioyO3-δ1 (s equal to 0.05 or larger) wherein Ln is a lanthanide element, Sc or Y, said composite material comprising at least two phases which are non-miscible, said composite material being obtainable by the glycine nitrate combustion method. Said composite material may be used for proving an electrode material in the form of at least a two-phase system showing a very low area specific resistance of around 0.1 Ωcm2 at around 600° C.
