The effects of Sr doping on the phase structure, sinterability, and electrochemical performance of BZCYYb electrolytes were systematically investigated. X-ray diffraction results confirmed that all Sr-doped BZCYYb powders retained a single-phase perovskite structure. Sintering experiments demonstrated that Sr doping significantly enhanced the sintering activity of the electrolyte powders, enabling dense ceramic pellets to be obtained at 1350&#730;C. Electrochemical impedance spectroscopy revealed that the electrical conductivity of the materials initially increased and then decreased with higher Sr content. The Ba<sub>0.75</sub>Sr<sub>0.25</sub>Zr<sub>0.1</sub>Ce<sub>0.7</sub>Y<sub>0.1</sub>b<sub>0.1</sub>O<sub>3-&#948;</sub> composition exhibited the highest conductivity of 18.77 &#215; 10<sup>&#8722;</sup><sup>3</sup> S&#183;cm<sup>&#8722;1</sup> at 700&#730;C, with an activation energy of 0.59 eV calculated from the Arrhenius relationship.
