摘　　要：在薄膜固体氧化物燃料电池中,为增加发生电化学反应的三相界面面积,燃料极和空气极通常制备成离子-电子混合传导性质的多孔形态。该研究将燃料极电化学反应(氢氧化反应)的催化剂——镍(Ni)和氧离子传导性好的氧化钪稳定的氧化锆(ScSZ)混合制备成离子-电子混合传导燃料极。实验结果显示,与纯Ni燃料极相比,所制备的Ni/ScSZ燃料极因其三相界面面积的增加,可显著降低极化电阻,但同时欧姆电阻也显著增加,从而最终导致燃料电池单池性能总体下降。The anode and the cathode of the thin film solid oxide fuel cells are usually fabricated as the mixed-ionic-electronic-conducting (MIEC)porous electrode in order to increase the triple phase boundaries where the electrochemical reactions occur.In this research,Ni,which is the catalyst of the hydrogen oxidation reaction in the anode,and scandia-stabilized zirconia,which presents a high oxygen ion conductivity,are mixed and finally fabricated as the MIEC anode.Experimental results show that triple phase boundaries can be increased and the polarization resistance can be decreased in comparison with the usage of pure Ni anode. However,the increasing of triple phase boundaries also causes the improvement of ohmic resistance,and the overall performance of fuel cell is still decreased.
