abstract = "Stabilized bismuth oxide material with fluorite structure (δ-Bi2O3) has been studied as a promising electrolyte material for intermediate temperature solid oxide fuel cells (IT-SOFCs) due to its high oxygen ion conductivity in mediate temperature. Especially, the ternary system Bi2O3–Er2O3–WO3 is widely concerned for its high ionic conductivity and thermal stability. In this study, regarding to its low melting point, the possibility to deposit dense Bi2O3–Er2O3–WO3 ((Bi2O3)0.705 (Er2O3)0.245 (WO3)0.05, EWSB) electrolyte by plasma spraying was examined. It was confirmed that the sintered EWSB bulk presents a high ion conductivity of 0.34 S cm-1 at 750 °C and excellent stability that indicates no structure transformation and conductivity degradation after annealing at 600 °C for 1000 h. The phase structure and cross-sectional microstructure of plasma-sprayed EWSB were characterized by XRD and SEM. Results showed that the as-plasma-sprayed EWSB presents a dense microstructure with well bonded lamellae. The XRD showed the formation of EWSB with δ-phase and a trace of β-phase, while the β-phase disappeared after annealed at 750°C for 10h. The deposited EWSB electrolyte presented the excellent ionic conductivity of 0.26 S cm-1 at 750 °C which can be directly applied to SOFC at intermediate temperature.",
