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- .delta. or (Ln1-xSrx)1- sFe1-yCioyO3-.delta. 1 (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 .OMEGA.cm2 at around 600°C.

La présente invention concerne un matériau composite adapté à une utilisation en tant que matériau d'électrode dans une pile à oxyde solide, ledit matériau composite se composant d'au moins deux conducteurs électroniques et ioniques mélangés non miscibles. Un matériau composite adapté à une utilisation en tant que matériau d'électrode dans une pile à oxyde solide est également fourni, ledit matériau composite étant basé sur (Gd1-xSrx)1-sFe1-yCoyO3-.delta. ou (Ln1-xSrx)1- sFe1-yCioyO3-.delta.1 (s égal à 0,05 ou plus) où Ln est un élément de lanthanide, Sc ou Y, ledit matériau composite comprenant au moins deux phases qui ne sont pas miscibles, ledit matériau composite pouvant être obtenu par le procédé de combustion de nitrate de glycine. Ledit matériau composite peut être utilisé pour fournir un matériau d'électrode sous forme d'au moins un système à deux phases présentant une très faible résistance spécifique de surface d'environ 0,1 .OMEGA.cm2 à environ 600°C.
