抄録

To evaluate the effects of H₂S on the performance of MCFC, the bench-scale cell tests and the half-cell tests were performed with fuel gas containing several levels of H₂S. The behaviors of sulfur compounds in the cell depend on the absorption of S on anode Ni and the solubility of H₂S by electrolyte. The solubility of H₂S by electrolyte relates to partial pressure of gas composition according to H₂S+CO₃²⁻+3H₂O=CO₂+4H₂+SO₄²⁻ and the current density. The higher the current density is, the lower the content of sulfate and / or sulfide ion in electrolyte is. Because the distribution of sulfate and / or sulfide ion depends on the convection of carbonate ion. In addition, the diffusion coefficients of sulfur in molten carbonate mixtures are derived from the bench-scale cell tests and the half-cell tests. The difference of these diffusion coefficients is discussed.
