Abstract:

Inserting a porous samaria-doped ceria (SDC) interlayer between yttria-stabilized zirconia (YSZ) electrolyte and anode is an effective method to enhancing the performance of intermediate-temperature solid oxide fuel cells (IT-SOFCs). In this work, the microstructure and morphology of the SDC interlayer were optimized by varying its thickness and sintering temperature. Results show that the SDC interlayer fabricated by utilizing once screen printing method and then sintered at 1300 °C for 2 h obtains the best electrochemical performance. The resulting polarization resistance and anodic overpotential (at a current density of 0.05 Acm^-2) were 0.84 Ωcm² and 0.07 V at 800 °C in H₂, reduced by factors of 4.7 and 5.6, respectively, when compared with the LSCM anode without the SDC interlayer.
