| Abstract: | Fuel flexibility is a major advantage of SOFCs, which allows the use of hydrocarbon fuels. These fuels may contain trace amount of H2S, which causes a drop in performance with the conventional Ni-based anode catalysts. Thereby, it is highly desirable to develop novel sulfur tolerant anode materials. A new ceramic based on B-site substitution of titanium with nickel in lanthanum-doped strontium titanates catalyst, was investigated (La0.2Sr0.7Ti0.95Ni0.05O3-δ or LST27). The material shows promising tolerance towards sulfur poisoning and reductionoxidation (“redox”) cycling. Three samples - LST27, LST27 impregnated with 5 wt.% Ni, and LST 27 impregnated with 5 wt.% Ni and 10 wt.% CeO2 - were evaluated for their behavior with respect to redox cycle tolerance and poisoning with H2S. Results showed that the anode withstands redox cycles; subsequently, a redox cycle is exploited to recover anode performance after expos to H2S. In other words, this anode can be regenerated from sulfur poisoning and thereby extend SOFC lifetime. |
