Porous La0 8Sr0 2MnO3 (LSMO) films have been prepared by metal organic chemical vapor deposition (MOCVD) technique for solid oxide fuel cell (SOFC) applications LSMO samples have been deposited on yttria-stabilized zirconia (YSZ) electrolyte pellets The adopted in situ strategy involves a molten mixture consisting of the La(hfa)(3) diglyme Sr(hfa)(2) tetraglyme and Mn(tmhd)(3) [Hhfa = 1 1 1 5 5 5-hexafluoro-2 4-pentanedione diglyme = bis(2-methoxyethyl) ether tetraglyme =2 5 8 11 14-pentaoxapentadecane Htmhd =2 26 6-tetramethyl-3 5-heptandione] precursors It has been shown that porous LSMO films can be obtained through an accurate tuning of processing parameters which affect the nucleation and growth processes The structural and compositional characterizations of these films carried out by X-ray diffraction (XRD) and energy dispersive X-ray analysis point to the formation of a single polycrystalline La0 8Sr0 2MnO3 phase The field emission scanning electron microscopy (FE-SEM) images confirm the formation of porous films To evaluate the electrochemical activity of the cathodic films an investigation by impedance spectroscopy (IS) has been performed (c) 2010 Elsevier B V All rights reserved
