英文摘要 | single layer lsm + ysz and double layers lsm/lsm + ysz composite electrodes with varying ysz content in the lsm + ysz layer have been prepared. the electrochemical properties and microstructures of the electrodes were investigated and compared. the electrochemical performance of the single layer lsm +ysz electrodes was improved when a certain amount of ysz was added due to the increase of the: three phase boundaries (tpb) by the addition of ysz, while excessive ysz addition (60%) caused a decrease in performance, because the in-phase resistance of the electrode increased so high, leading to a reduced effective electrode area. the problem was eliminated by a double-layer lsm/lsm + ysz composite electrode, in which a pure lsm layer functioned as a current collector and reduced the in-phase resistance. as a result, both large tpb area and low ohmic resistance were assured in this kind structure. at 1223 k, the double-layer composite electrode with 50 wt. % ysz has the lowest polarization resistance of 0.3 omega .cm(2). |
