The proton conductors La_1-xSr_xNbO_4-σ (0≤x≤0.02) are synthesized by solid-state reaction and their properties are characterized. XRDanalysis shows that all composition samples are monoclinic structure; with an increase in Sr doped amount, cell volume becomes big; La_1-xSr_xNbO_4-σ samples display excellent chemical stability in boiling water and carbon dioxide atmosphere. SEManalysis shows that after the La_1-xSr_xNbO_4-σ powders are sintered at 1500 ℃ for 8 h in air, dense samples with uniform crystalline size are obtained; The Sr doping inhibits crack formation and excessive growth of crystal grain; with an increase in Sr doped amount, crystal grain size becomes small. ACimpedance spectroscopy analysis indicates that conductivities of LaNbO₄ are changed by Sr doping and among all samples, La_{0.995_Sr0.005}NbO_4-σ is of the highest conductivity; the conductivities of the La_1-xSr_xNbO_4-σ samples in humid 5% H₂-Ar atmosphere are much higher than that those in dry air; conductivity of La_{0.995_Sr0.005}NbO_4-σ is 0.003 S·cm^-1 in humid 5% H₂-Ar atmosphere at 800 ℃ and its conducting activation energy is 0.44 eV.
