摘要：

采用原位浸渍法一步烧结成型制备了NiO-BaZr_0.1Ce_0.7Y_0.1Yb_0.1O_3-δ（BZCYYb）/SDC/LSCF管状结构阳极支撑型SDC电解质膜固体氧化物燃料电池（SOFCs）。以加湿H₂（约含有体积分数为3%的水）为燃料，空气为氧化剂，研究了电池的电化学性能、热循环性能和工作电压下运行的稳定性。结果表明：电池在600、650、700、750、800℃的开路电压分别为1.084、1.074、1.067、1.058、1.046 V；最大输出功率密度分别为0.12、0.25、0.38、0.54和0.70 W·cm^-2。单电池在700℃和0.7 V连续放电测试过程中稳定运行，没有明显的下降和衰退。单电池经历了11次热循环，输出功率稳定，能够经受住重复启动考验。

Abstract:

A tubular anode supported SOFCs with NiO-BaZr_0.1Ce_0.7Y_0.1Yb_0.1O_3-δ (BZCYYb)/SDC/LSCF structure was fabricated by in-situ dip coating and one-step sintering technology. The electrochemical performance, thermal cycling performance and operating stability under working voltage of the single cell were obtained with the moist H₂ (3% (vol) H₂O) as fuel and air as oxidant. The results indicate that the open-circuit voltage were 1.084,1.074,1.067,1.058 and 1.046 V, and the maximum power densities were 0.12,0.25,0.38, 0.54 and 0.70 W·cm^-2 at 600,650, 700, 750 and 800℃, respectively. The results also suggest that the single cell running stablely in continuous discharge testing process at 700℃ and 0.7 V without obvious decline. The single cell had successfully experienced thermal cycling test for eleven times and the output power was stable. These results presented that the cell showed good thermo-mechanical properties and was able to withstand the repeated start-up tests. The developed SOFCs with new kind of anode (NiO-BZCYYb) are highly promising for industrial and commercial development applications in future.
