Y0.08Sr0.92FexTi1−xO3−δ perovskite for solid oxide fuel cell anodes

► We fabricated Y and Fe co-doped SrTiO3 perovskite. ► It can be used as an oxide anode material of solid oxide fuel cells. ► Yttrium doping is effective to improve the phase stability in hydrogen. ► Electrical conduction in air and H2 was governed by the acceptor concentration and electrons due to the oxygen loss, respectively. ► Y and Fe co-doped SrTiO3 showed comparable interfacial resistance compared with Ni-YSZ cermet anode.
