Abstract

<abstract abstract-type="main"> <title>SUMMARY</title> <p>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 &amp; Sons, Ltd.</p> </abstract>
