A Hydrogen Sulfide/Air Solid Oxide Fuel Cell

A fuel cell which uses pure hydrogen sulfide as fuel and a solid electrolyte of ceria stabilized with yttria (YSC) has been proposed, with the configuration H₂S, Pt/YSC/Pt, O2 (air), operating at temperatures of 600 to 800° C. Initial experiments will use platinum electrodes, with subsequent runs using various perovskite type electrodes. The YSC electrolye system exhibits better ionic conductivity than the more familiar YSZ electrolytes, and thus the fuel cell will operate at a lower temperature range. Cell component manufacture, cell experiments, and analytical techniques are discussed.
