摘要：

Oxide based two phase composite electrolyte (Ce0.9Gd0.1O2-Y2O3) was synthesized by coprecipitation method. The nanocomposite electrolyte showed the significant performance of power density 785 mW cm(-2) and higher conductivities at relatively low temperature 550 degrees C. Ionic conductivities were measured with ac impedance spectroscopy and four-probe dc method. The structural and morphological properties of the prepared electrolyte were investigated by scanning electron microscope (SEM). The thermal stability was determined with differential scanning calorimetry. The particle size that was calculated with Scherrer formula, 15-20 nm, is in a good agreement with the SEM and X-ray diffraction results. The purpose of this study is to introduce the functional nanocomposite materials for advanced fuel cell technology to meet the challenges of solid oxide fuel cell. [DOI: 10.1115/1.4003634]
