Symmetrical cells with Fe - BaCe0.2Zr0.6Y0.2O2.9 composite electrodes are produced by screen printing and infiltration, using BaCe0.2Zr0.6Y0.2O2.9 as electrolyte. The electrochemical performance of the composite electrode is studied by impedance spectroscopy at 250-500 degrees C in dry and wet hydrogerdnitrogen mixtures. The polarization resistance is 1.6 Omega cm(2) at 500 degrees C in wet H-2 (pH(2)O = 0.01 atm), and has an activation energy of 0.72 eV. The cells degrade upon exposure to temperatures up to 500 degrees C, likely due to coarsening of the iron nanoparticles and loss of electronic percolation in the composite anode. Iron has potential to be a promising anode material for PCFCs, once electronic percolation in the. electrode is improved and degradation is reduced. (C) 2014 The Electrochemical Society.
