Strontium doped lanthanum vanadate (La0.7Sr0.3VO3, LSV) is a sulfur tolerant anode material capable of selectively oxidizing H2S over H2 and chemical, electrical and thermal properties of this material have been studied to date. This research attempted to determine the best thickness of LSV/YSZ bi layer anodes operating on coal syngas containing 300 ppm H2S at 800 °C and 900 °C, based on electrochemical response. Screen printing technology was used as the low cost method to manufacture anodes. The best anode thickness at 800 °C was 65 μm while 80 μm was the best thickness at 900 °C. The results suggested that the anode performances were governed by catalytic activity of LSV, resistance to electron transfer and the length of gas diffusion paths which was a function of anode thickness. The cell microstructures exhibited an undisturbed porous structure at the electrode electrolyte interface after 48 hour test runs.
