Abstract

BaCeO3-based proton conductor BaCe0.5Zr 0.3Y0.16Zn0.04O3-δ (BCZYZn) was adopted as a part of the oxide-carbonate composite electrolyte. The total ionic conductivity of BCZYZn-carbonate composite is 0.28 S cm-1 at 500 C. Perovskite oxide SrFe0.7Mn0.2Mo0.1O 3-δ was developed and used as cathode. It was found that SrFe0.7Mn0.2Mo0.1O3-δ exhibits a primitive cubic structure with space group Pm3m(221); a = 3.8790(1) Å, V = 58.364(1) Å3. The electrical conductivity of SrFe 0.7Mn0.2Mo0.1O3-δ is 15-26 S cm-1 in the temperature range 400-700 C measured by d.c. method. Single cell with BCZYZn-carbonate composite electrolyte and SrFe 0.7Mn0.2Mo0.1O3-δ cathode was fabricated and tested with humidified H2 (∼3 vol% H2O) as fuel and air as oxidant. A similar configuration cell with lithiated NiO cathode was also constructed for comparison. It was found that neither BaCe 0.5Zr0.3Y0.16Zn0.04O 3-δ nor SrFe0.7Mn0.2Mo 0.1O3-δ is chemically compatible with (Li,Na) 2CO3. The fuel cell performance is not as good as those based on doped ceria-carbonate electrolytes.
