Electrochemical behavior of solid oxide fuel cell anodes based on infiltration of Y-doped SrTiO3

► Y-doped SrTiO3 infiltrated porous YSZ was investigated as an alternative anode. ► Amount of infiltrate must be optimized to balance conductivity and polarization. ► Heat treatment conditions highly affect the purity and crystal size. ► Electrochemical performance of the infiltrated anodes is highly enhanced. ► H2S remarkably boosts the electrochemical performance under methane fuel.
