  • Conductive solid oxide fuel cell electrolyte composition and a method for preparing the same
    Patent number: 10797335
    Abstract: The present disclosure relates to a conductive Solid Oxide Fuel Cell (SOFC) electrolyte composition that is compatible with Low Temperature Co-fired Ceramic (LTCC). The conductive SOFC electrolyte composition comprises gadolinium doped ceria, glass composite and additives. The conductive SOFC electrolyte composition is physically and chemically compatible with the LTCC. A process for preparing a conductive SOFC electrolyte composition is also provided in the present disclosure.
