The proton-conducting solid oxide fuel cell composed of H₂S,(CoS-Mo₂S)/BaCe_0.475Zr_0.475Y_0.05O_3-δ/Ag,air was studied at atmospheric pressure and 600~800℃ with the aim of preparation and perfor-mance of the cell,the effects of different temperatures and different fuel flow rates on the removal of H₂S.The results indicate that the removal of H₂S was linearly proportional to current density.The performance of the cell and H₂S removal were improved by increasing temperature,the optimal working temperature was in a range of 700~800℃.Increasing fuel flow rate promoted the removal of H₂S between 30~80 mL/min.71% of H₂S removal was obtained at 800℃ and 80 mL/min,with an open circuit voltage of 0.72 V and a maximum current density of 2.9×10^-2 A/cm².
