Stability of solid oxide fuel cell anodes based on YST-SDC composite with Ni catalyst

► The use of Ni/YST-SDC ceramic anode was proposed to replace Ni-based cermet. ► Addition of nickel enhances the electrochemical performance without drawback effects. ► The excellence of YST-SDC ceramic framework could maintain the stable performance. ► Ni/YST-SDC offers certain advantages and highly stable performance in severe conditions.
