[en] The possibility for obtaining energy based on oxidation of sulfide and sulfite ions while simultaneously solving an environmental problem is regarded. The catalysts used for the processes are shown. Different constructions of the fuel cells are studied. An analysis of the results so far is made, as well as possible future development. Key words: fuel cells, sulfides, sulfites

[en] Sulfides and sulfites are toxic pollutants from different industrial, domestic and natural sources. A way for their disposal and transformation to harmless products, even with a market value is their oxidation. Different type of catalysts for sulfide and sulfite oxidation to sulfates are studied and compared. The aim is to make a screening for the most appropriate catalyst for the process that can be used separately or that can be incorporated into electrodes in a fuel cell driven by the oxidation process. The technology for manufacturing of electrodes on the base of the obtained catalyst is given.
