| Abstract: | A novel electrolyte CaZr_(0.1)Ti_(0.9)O_3 for solid oxide fuel cell(SOFC) was synthesized by a newly sol-combustion method. The structure and conduction properties of the sample were systematically investigated via XRD and electrochemical methods. The results show that CaZr_(0.1)Ti_(0.9)O_3 powders were successfully prepared by the sol-combustion technique. The powder shows a high sinterability, and a relative density of 95% at a sintering temperature of 1 400 ℃. Electrochemistry measurements show that the CaZr_(0.1)Ti_(0.9)O_3 ceramics has a relatively high oxide ionic conductivity (σ_(800℃) = 2. 24 × 10~(-3) S/cm) , low electrical activation energy (E_a = 0. 89 eV) in the low-temperature range. |
