摘要：
Barium cerate doped with tetravalent Th is successfully synthesized by a traditional Pechni method. The BaCe0.7Th0.1Y0.2O3-delta (BCT71) composites were applied to an anode supported coin single cell consisting of Ni-BCT71 anode/BCT71 electrolyte/ BCT71-La0.7Sr0.3FeO3-delta cathode. The assembled cell is tested from 600 degrees C to 700 degrees C with humidified hydrogen (similar to 3% H2O) as the fuel and the static air as the oxidant. An open-circuit potential of 0.93 V and a maximum power density of 104 mW cm(-2) are obtained for the single cell with an interface resistance of 0.98 Omega cm(2) at 700 degrees C.
