Seawater is the most abundant resource on our planet and fuel production from seawater has the notable advantage that it would not compete with growing demands for pure water. This Review focuses on the production of fuels from seawater and their direct use in fuel cells. Electrolysis of seawater under appropriate conditions affords hydrogen and dioxygen with 100 % faradaic efficiency without oxidation of chloride. Photoelectrocatalytic production of hydrogen from seawater provides a promising way to produce hydrogen with low cost and high efficiency. Microbial solar cells (MSCs) that use biofilms produced in seawater can generate electricity from sunlight without additional fuel because the products of photosynthesis can be utilized as electrode reactants, whereas the electrode products can be utilized as photosynthetic reactants. Another important source for hydrogen is hydrogen sulfide, which is abundantly found in Black Sea deep water. Hydrogen produced by electrolysis of Black Sea deep water can also be used in hydrogen fuel cells. Production of a fuel and its direct use in a fuel cell has been made possible for the first time by a combination of photocatalytic production of hydrogen peroxide from seawater and dioxygen in the air and its direct use in one‐compartment hydrogen peroxide fuel cells to obtain electric power.

“…From theoretical calculations, it has been found that it is possible to produce 270 Mtons of H 2 , corresponding to 808 Mtons of gasoline or 766 Mtons of natural gas [1,4]. The Hydrogen production process from Black Sea consists of the following steps: a) pumping of sea water at ~1000 m depth, b) extraction of concentrated H 2 S/H 2 O mixtures, c) co-electrolysis of H 2 S and H 2 O to H 2 in H + -conducting electrochemical reactors.…”

Abstract. The present study aims to examine and evaluate the concept of H2S decomposition to H2 production in (H + )-conducting electrochemical reactors. In such a complex process, one of the major issues raised is the optimal selection of materials for the electrochemical cell. Specifically, the anode electrode should exhibit high catalytic activity and electronic conductivity, in order to make the process efficient. In this context, and before the electrochemical tests, a number of transition metal catalysts supported on CeO2 were prepared using the wet impregnation method and tested for their performance regarding the activity/stability of the H2S decomposition reaction, in the absence and presence of H2O. The experimental results are accompanied by the corresponding thermodynamic calculations, at various reaction conditions. The physico-chemical characteristics of the employed catalysts were determined using the BET, XRD, SEM and elemental analysis methods. The experimental results showed that the catalysts 20% wt. Co/CeO2 and 30% wt. Co/CeO2 exhibit high H2S conversions, in the absence and presence of H2O respectively, comparable to conversions indicated by thermodynamics and with remarkable stability, which is attributed to the in-situ sulfation of catalysts' active components during their exposure at the feedstock mixture.

SUMMARY In this study, the oxidation mechanism of hydrogen sulfide (H2S) is investigated, and a fuel cell operating with acidic peroxide as oxidant and basic hydrogen sulfide as fuel is constructed. A stable solid state H2S/H2O2 fuel cell has been developed at the temperature of 298 K. A nickel anode catalyst has been examined using Nafion‐117 as a proton‐conducting membrane. In an operating with the acidic hydrogen peroxide (H2O2) as oxidant, the cell potential was increased to a value of 0.85 V at 298 K. The main conclusion of this study is the management to increase the cell potential to 850 mV at 25 °C, whereas this value can only be achieved in the H2S/O2 fuel cell at 850–1000 °C. Moreover, there exists no prior work on the H2S/H2O2 fuel cell research. Copyright © 2012 John Wiley & Sons, Ltd.
