  • Chemically stable proton conducting doped BaCeO
    Patent number: 10497959
    Abstract: Solid electrolytes, anodes and cathodes for SOFC. Doped BaCeO3 useful for solid electrolytes and anodes in SOFCs exhibiting chemical stability in the presence of CO2, water vapor or both and exhibiting proton conductivity sufficiently high for practical application. Proton-conducting metal oxides of formula Ba1?xSrxCe1?y1?y2?y3Zry1Gdy2Yy3O3?? where x, y1, y2, and y3 are numbers as follows: x is 0.4 to 0.6; y1 is 0.1-0.5; y2 is 0.05 to 0.15, y3 is 0.05 to 0.15, and cathode materials of formula II GdPrBaCo2?zFezO5+? where z is a number from 0 to 1, and ? is a number that varies such that the metal oxide compositions are charge neutral. Anodes, cathodes and solid electrolyte containing such materials. SOFC containing anodes, cathodes and solid electrolyte containing such materials.
