Metal-supported solid oxide fuel cells with the structure of Ni-Ce0.8Sm0.2O2-delta (SDC) infiltrated porous 430L anode, YSZ electrolyte and in-situ sintered (Bi2O3)(0.7)(Er2O3)(0.3)-Ag (ESB-Ag) cathode was fabricated and a high power density of 1.3 W cm(-2) was obtained at 750 degrees C. Cell performance was enhanced by the Ni-SDC infiltrated porous 430L anode applied here. Replacing the cell electrolyte by SSZ with higher oxide ionic conductivity than that of the YSZ resulted in an improved power density of 1.55 W cm(-2) at 750 degrees C and the improvement was more obvious at the low temperature. Moreover, cell stability was improved by the application of ESB-Ag-La(0.7)4Bi(0.10)Sr(0.16)MnO(3-delta) (LBSM) composite cathode. (C) 2014 The Electrochemical Society. All rights reserved.
