摘　　要：通过高温固相法合成了BaZr 1-x Sm x O 3-δ(x=0.05,0.1,0.15,0.2)电解质材料,并对材料的物相结构进行了XRD表征。分别在空气和4%H 2O/H 2中,温度范围为500~800℃下,通过电化学工作站测试了该电解质材料的电学性能。研究发现,稀土元素Sm的掺杂对BaZrO 3电解质材料的电学性能有重大影响,当Sm元素的掺杂量为0.15时,电解质的电导率达到最大值。结果表明,Sm的掺杂可以有效提高BaZrO 3电解质材料的电导率。BaZr 1-x Sm x O 3-δ(x=0.05,0.1,0.15,0.2)electrolytes were synthesized by high temperature solid phase method,and the phase structures were characterized by XRD.The electrochemical properties of the electrolytes were tested by electrochemical workstation in the atmosphere of air or 4%H 2O/H 2 at 500~800℃.Doping Sm had a great influence on the electrical properties of BaZrO 3.When the doping amount of Sm was 0.15,the conductivity of electrolyte reached the maximum.The results indicated that doped Sm can effectively improve the conductivity of BaZrO 3.
