Stability and performance of SOFC with SrTiO3-based anode in CH4 fuel

► La-doped SrTiO3 (LST) was used as an alternative anode. ► Co was added in LST for the better performance. ► Ni was impregnated to the LST-GDC anode. ► LST-based anode showed good tolerance to the carbon-induced deactivation. ► Ni-impregnated LST-GDC anode showed better performance compared to the conventional Ni-GDC both in H2 and CH4 fuel.
