Summary:Title screen
NiO/YSZ anode layers for metal-supported solid oxide fuel cells (MS-SOFCs) were fabricated by spark plasma sintering (SPS). SPS parameters were optimized in order to achive anodes of the desired microstructure. The effect of sintering conditions on microstructure of NiO/ YSZ was studied by scanning electron microscopy and Xray diffractometry. Also NiO/YSZ layers were formed on porous metal supports by a screen-printing method and sintered in inert atmosphere and vacuum by conventional sintering technique. At temperatures above 1,200 °С in inert atmosphere and vacuum nickel oxide dissociation and its massive agglomeration are observed during conventional sintering. SPS process allows sintering of NiO/ YSZ granules without NiO dissociation, Ni agglomeration and the metal substrate oxidation at 1,100 °С. SPS sintered anodes demonstrate sufficiently homogeneous distribution of NiO and YSZ making a conduction path for electrons and ions. Well-bonded metal support/anode interface was obtained.
