Ni infiltrated YSZ anode stabilization by inducing strong metal support interaction between nickel and titania in solid oxide fuel cell under accelerated testing

► Addition of 4% TiO2 to 12% and 16% Ni infiltrated YSZ matrix reduces Ni coarsening. ► Impedance spectra of Ni-TiO2-YSZ anode shows overall drop in ohmic resistance after addition of 4% TiO2. ► Performance of SOFC with 4% TiO2-16% Ni-YSZ anode increased from 226 mW/cm2 at 7 h to 400 mW/cm2 at 94 h ► Synergistic effect of TiO2-Ni through SMSI may have prevented Ni coarsening.
