Abstract:
It is well known that Black Sea water has a high H2S content, estimated to about 4.6x109 tons, with its hydrogen sulfide layer beginning at about 200 meters below the surface. H2S, an acid gas, considered to be an environmental pollutant can be explored as a source of hydrogen. The potential of hydrogen sulfide recovering from sea water from Black Sea using a custom made fuel cell stack with Nafion membranes, Pt and Pt-Ru catalysts was investigated as an alternative at actual technologies. Different H2S concentrations ranging in the interval 10-150 mg/l were considered for estimating the recover efficiency. The concentration of hydrogen sulfide decreased after 2 hours of repeated circulation of solution, while colloidal sulfur was produced. As expected, current density and potential generated by the fuel cell increase with H2S concentration. These preliminary results prove that fuel cell can be considered a promising approach in hydrogen sulfide conversion.
