The electrochemical performance of a solid oxide fuel cell with the configuration of H2S, (MoS2+NiS+Ag)/YSZ/Pt and air was examined at an atmospheric pressure and 750～850℃. It is found that the increasing of temperature helps to enhance the ionic conductivity of electrolyte and makes the cell performance better. When the H2S stream flows into the anode and air stream into the cathode, the maximum electric current density and the maximum power density go respectively up to 800mA/cm2 and 84mW/cm2 at 750℃, while those at 850℃ respectively to 1750mA/cm2 and 200mW/cm2.
