Such interlayers act as diffusion barriers to protect the yttria-stabilized zirconia electrolyte, preventing possible degradation when mixed ionic–electronic conductor (La,Sr)(Co,Fe)O3−ı 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 depositions, which resulted in increased electrochemical properties of fuel cells.1599-1604openAccessgadolinium oxidesdoped materialscerium oxidessolid oxide fuel cellselectrochemistryArtigo de periódico619510.1016/j.jpowsour.2009.09.050https://orcid.org/0000-0003-0708-2021
