摘要：

A formulation of tungsten and nickel combined with CeO2 (WNi-Ce) was prepared and evaluated as sulfur-tolerant anode for SOFC at intermediate temperature. Structural and morphological changes that take place in the system upon interactions with hydrogen sulfide were analyzed. The electrochemical performance was tested in a single cell, WNi-Ce/LDC/LSGM/LSFC, varying H2S concentration (0-500 ppm) at 750 degrees C using I-V curves, impedance spectroscopy and load demands. The highest cell performance was reached in H-2 and decrease with H2S content increase in the fuel from 226mWcm(-2) in pure H-2 to 108mWcm(-2) in 500 ppm H2S/H-2. Essentially, no decay in the cell performance was observed in the several short-term load tests studied under several H2S concentration (0-500 ppm) during 1h, and even in 500 ppm H2S/H-2 during 70 h, indicating that this material could be a potential sulfur-tolerant anode.
