摘要	By using a new combustion synthesis method, the glycine-nitrate process, all the nano-size materials were prepared for a single solid-oxide fuel cell (SOFC), in which (CeO2)(x) (SmO1.5)(1-x)(x = 0. 9, 0. 85, 0. 8) were used as the electrolytes, La0.6Sr0.4Fe0.8Co0.2O3 with 50% samaria-doped ceria (SDC) was selected as the cathode material, and a SDC-NiO-Ni composite powder was used as the anode material. In this study, the performance of the SOFC was obtained up to 750 degreesC, the maximum power density of 0. 104 W/cm(2) and a short circuit current density of 500 mA/cm(2) of the cell was achieved at 750 degreesC by using (CeO2)(0.9)(SmO1.5)(0.1) electrolyte. The inferior SOFC performance of the (CeO2)(0.8)(SmO1.5)(0.2) electrolyte was due to the physical discontinuity at the clearly grain boundary and could effectively introduce barriers to ionic conduction in reducing atmosphere, while the (CeO2)(0.9)(SmO1.5)(0.1) electrolyte's boundary tends to be merged.
