摘要：

La0.9Ba0.1Ga0.8Mg0.2O3-delta, an alternative electrolyte candidate for the ceramic fuel cell, exhibits an oxygen ion conductivity higher than 0.1 S/cm at 800 degrees C. The maximum power density of the single cell Ni/electrolyte composite anode/La0.9Ba0.1Ga0.8Mg0.2O3-delta electrolyte/Sm0.5Sr0.5CoO3-delta cathode system was measured as 0.21 W/cm(2) at 1000 degrees C.
