Electrolyte-cathode assembly for a fuel cell

Patent ·
OSTI ID:6140877
;
An electrolyte cathode assembly for a solid electrolyte fuel cell suitable for operation at high temperatures comprises a gas-tight body made of a solid ceramic electrolyte which is capable of conducting oxygen ions having in contact with it and secured to it a layer of electron-conducting material which is a mixture of doped indium oxide In/sub 2/--O/sub 3/ and a ceramic material which is capable of conducting oxygen ions at the cell operating temperature, the said layer being covered by a compact surface layer of a ceramic material which is capable of conducting both electrons and oxygen ions.
