ABSTRACT:
An electrolyte cathode assembly for a solid electrolyte fuel cell intended for operation at high temperature comprises a solid ceramic electrolyte gas-tight body which is capable of conducting oxygen ions, the electrolyte having in contact with it and secured to its surface a layer of electron-conducting material which is a compact layer made up of a mixture of doped indium oxide In.sub.2 O.sub.3 and a ceramic material which is capable of conducting both oxygen ions and electrons at the cell operating temperature, the said layer being covered with a surface layer, which is permeable to gas, of doped indium oxide In.sub.2 O.sub.3 having a dendritic structure.
