dc.description.abstract | Potential of BaZr0.1Ce0.7Y0.2O3-delta (BZCY) electrolyte prepared by ammonium carbonate coprecipitation was investigated for application in solid oxide fuel cells (SOFCs). An 8 mu m thick BZCY electrolyte layer was deposited on a porous Ni-BZCY anode. A slurry mixture of BZCY-LaSr3Co1.5Fe1.5O10-delta (LSCF) was used as the cathode. The ionic conductivities of the BZCY electrolyte were 5.0 x 10(-2) and 1.8 x 10(-2) S cm(-1) at 750 and 550 degrees C, respectively, and the conduction activation energy was 0.42 eV. A fabricated single cell exhibited excellent maximum power densities of 1.39 Wcm(-2) at 750 degrees C and 0.72 Wcm(-2) at 600 degrees C using hydrogen as fuel. Further the cell was also exposed to CH4 (70%) and CO2 (30%) in the anode side as fuel. Under biogas the maximum power densities were 0.79 W cm(-2) at 750 degrees C and 0.28 W cm(-2) at 600 degrees C. The characteristics of the electrolyte were quantified by measuring the total conductivities across a range of temperatures. Copyright (C) 2015, Hydrogen Energy Publications, LLC.
