Much research into fuel cells operating at a temperature below 800℃. is being performed. There are sig-nificant efforts to replace the yttria-stabilized zirconia electrolyte with a doped ceria electrolyte that has high ionic con-ductivity even at a lower temperature. Even if the doped ceria electrolyte has high ionic conductivity, it also shows highelectronic conductivity in a reducing environment, therefore, when used as a solid electrolyte of a fuel cell, the power-generation efficiency and mechanical properties of the fuel cell may be degraded. In this study, gadolinium-doped ceriananopowder with Al2O3 and Mn2O3 as a reinforcing and electron trapping agents were synthesized by ultrasonic pyrol-ysis process. After firing, their microstructure and mechanical and electrical properties were investigated and comparedwith those of pure gadolinium-doped ceria specimen.
