Abstract

The growth and electrochemical properties of gadolinia-doped ceria (GDC) inlet layers deposited by bias-assisted magnetron sputtering in solid oxide fuel cells have been investigated Such interlayers act as diffusion barriers to protect the yttria-stabilized zirconia electrolyte. preventing possible degradation when mixed ionic-electronic conductor (La,Si)(Co,Fe)O(3-delta) is used as the cathode The dependence of the applied bias during the sputtering deposition on both the interlayer microstructure and fuel cell performance has been studied in anode-supported single cells. The main experimental results Showed that bias-assisted sputtering of GDC interlayers produced microstructures denser than those of unbiased deposit ions, which resulted in increased electrochemical properties of fuel cells (C) 2009 Elsevier B.V All rights reserved (AU)
