Chemical cogeneration in solid electrolyte cells: The oxidation of H2S to SO2

Article abstract of DOI:10.1149/1.2096899

The anodic oxidation of H₂S was investigated in the solid electrolyte fuel cell H₂S, S_x, SO₂, PUZrO₂(8% Y₂O₃)/Pt, air operating at atmospheric pressure and temperatures 650° to 800°C. It was found that the fuel cell product selectivity crucially depends on the ratio M of the fluxes of oxygen anions O^2- and H₂S reaching the porous Pt anode. When M<0.33, elemental sulfur is the major product, and the anode is severely polarized. For higher M values, the product selectivity to SO₂ exceeds 99% at H₂S conversions as high as 99%. The cell appears to be a promising candidate for the cogeneration of electric energy and sulfur dioxide.
