Fabrication and electrochemical characterization of anode-supported microtubular solid oxide fuel cells based on Ce0.8Sm0.2O2-d electrolytes

Journal Article


Abstract


  • Anode‐supported microtubular solid oxide fuel cells (SOFCs) based on Ce0.8Sm0.2O2‐δ (SDC) electrolytes were prepared using phase inversion and vacuum‐assisted coating techniques. With La0.6Sr0.4Co0.2Fe0.8O3‐δ‐Ce0.8Sm0.2O2‐δ (LSCF‐SDC) as a cathode, the maximum power densities of the cell reached 38, 104, and 168 mW/cm2 at 500°C, 550°C, and 600°C, respectively; and the corresponding open‐circuit voltages (OCVs) were 0.74, 0.73, and 0.71 V. Furthermore, the OCVs could be significantly improved by way of brush painting a BaZr0.1Ce0.8Y0.1O3‐δ‐Ce0.8Sm0.2O2‐δ (BZCY‐SDC) layer on the SDC electrolyte membrane, achieving 0.81, 0.80, and 0.76 V at 500°C, 550°C, and 600°C, respectively.
