Abstract:
Hydrogen sulfide is an environmental pollutant and abundant in various sulfurous waters such as Black Sea. Hydrogen sulfide is in the same time a potential energetic materials as source for hydrogen production. In this respect, designing an appropriate fuel cell with proton exchange membranes (PEMFC) for hydrogen sulfide recovering from sulfurous water is challenge. This study reports a PEMFC with Pt/Pt-Ru catalysts and membrane with perflurosulfonic ionomer. PEMFC was calibrated using a couple methanol-water/ air and further to water with 1 mg/l hydrogen sulfide concentration. Even though power density and current density are then times lower than methanol-water the FC with hydrogen sulfide show a promising perspective for sulfurous water treatment.
