Claims20
A proton-conducting ceramic electrolyte comprising:
- a sintered multi-metal oxide solid solution defined by grains that derive from pre-sintered precursor particulates having an average particle diameter from 1 nanometer to 20 nanometers, wherein the sintered multi-metal oxide solid solution exhibits a uniform elemental distribution across and within individual grains;
- wherein the individual grains comprise a single crystalline phase with minimal secondary phases detectable by x-ray diffraction.
A solid oxide cell comprising:
- a proton-conducting ceramic electrolyte disposed between an anode and a cathode;
- wherein the proton-conducting ceramic electrolyte comprises:
- a sintered multi-metal oxide solid solution defined by grains that derive from pre-sintered precursor particulates having an average particle diameter from 1 nanometer to 20 nanometers, wherein the sintered multi-metal oxide solid solution exhibits a uniform elemental distribution across and within individual grains;
- wherein the individual grains comprise a single crystalline phase with minimal secondary phases detectable by x-ray diffraction
