| Abstract: | A sulfur-oxygen solid oxide fuel cell（SOFC） was assembled, by using Sm0.2Cc0.8O1.9 （SDC） as solid electrolyte material, La0.6Sr0.4Co0.2Fe0.8O3-δ （LSCF） as cathode material, powders of La0.8Mg0.2Cr0.8Zn0.2O3-δ, La0.8Mg0.2Cr0.8Al0.2O3-δ and La0.8Mg0.2Cr0.8Zr0.2O3-δ synthesized with sol-gel method as anode materials. Performances of the SOFC anode were characterized by taking S vapor and SO2 gas as fuel gas, respectively. Results show when S vapor is used as fuel gas, La0.8Mg0.2Cr0.8Zn0.2O3-δ is used as anode material,maximum output open-circuit-voltage （OCV） of 420 mV and maximum power density of 23 mW/cm2 are generated at 750 ℃ ;When SO2 is used as fuel gas, maximum output OCV of 162 mV and maximum power density of 2 mW/cm2 are generated at 650 ℃. The order of anode catalytic efficiency is as follows La0.8Mg0.2Cr0.8Zn0.2O3-δ 〉 La0.8Mg0.2Cr0.8Al0.2O3-δ 〉 La0.8Mg0.2Cr0.8Zr0.2O3-δ. |
