Hydrogen sulfide H2S existing in the deep-waters of the Black Sea may become an alternative energy source. Use of the fuel cell for obtaining of electricity from hydrogen sulfide of the Black Sea waters is suggested in the present work. Many researches are carried out in the sphere of use of hydrogen sulfide as fuel raw material, but in all considered works the oxidation of gaseous hydrogen sulfide was realized with the use of expensive catalysts and composition materials at high temperature (800-1000 ), which is not commercially profitable for production. Dissolved in water hydrogen sulfide exists in Black Sea waters. Membranes (anion- and cation-exchange) for fuel cells are selected and processes passing on certain electrodes of the fuel cell are studied. The values of current and voltage were measured during the experiment. Current density and power were calculated concerning the visible area of given electrode. Laboratory and large-laboratory models of the fuel cell were created. The experimental study of these models was carried out on different electrodes. The most efficiently working electrode materials, which have as a function of electrode, so the function of catalyst, are selected. The selected electrode-catalyst was not poisoned by hydrogen sulfide and its oxidation products. The lifetime of spent anionic membrane (Ralex –АМ-РР) was established - 320 hours. It was shown, at what conditions of external load (resistance - 1000 ohm) the fuel cell works most effectively, when it has maximal power.
