- Abstract
- Much research into fuel cells operating at a temperature below 800oC. is being performed. There are significantefforts to replace the yttria-stabilized zirconia electrolyte with a doped ceria electrolyte that has high ionic conductivityeven 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 powergenerationefficiency 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 pyrolysisprocess. After firing, their microstructure and mechanical and electrical properties were investigated and comparedwith those of pure gadolinium-doped ceria specimen.
