| Abstract: | Nanosized particles of Ce0.8Gd0.2O1.9(GDC) electrolyte materials for low-temperature solid oxide fuel cells were prepared by a so called sol-combustion technique using citric acid as the chelating agent.The effects of different sintering temperature were investigated on the evolution of crystalline phase,particle size,and lattice parameters of the resulted GDC.Ultra-fine GDC powders of around 30nm in diameter were successfully prepared by the sol-combustion technique.The powders showed a high sintering acti... |
