| description | <p></p><div> <p>Hydrogen sulfide (H<sub>2</sub>S) is an abundantly present, corrosive, and noxious compound. Though the Claus process is effective in processing H<sub>2</sub>S, it extracts minimal energy from H<sub>2</sub>S. Solid oxide fuel cell (SOFC) can harvest the chemical energy of H<sub>2</sub>S to generate electric power. For practical implementations, the performance of H<sub>2</sub>S/air SOFCs and the potential losses in the system are determined. The present study aims to develop the complete electrochemical model of H<sub>2</sub>S/air SOFC system and to analyze its performance. The theoretical cell potential of H<sub>2</sub>S/air SOFC is determined, and the deviations from the theoretical cell potential due to polarization are studied. According to the results, H<sub>2</sub>S/air SOFC generates electric power with energetic, exergetic, and voltaic efficiencies of 59.0%, 43.0%, and 89.7%, respectively, at atmospheric pressure and a temperature of 1100 K. Further efficiencies can be achieved if the output heat is utilized for useful applications. Moreover, the SO<sub>2</sub> formed by the electrochemical reactions in SOFC can be recovered as elemental sulfur or sulfuric acid as an additional useful commodity. In brief, this study demonstrates the performance of H<sub>2</sub>S/air SOFC to serve as a basis for the implementation of H<sub>2</sub>S/air SOFC toward eliminating the environmental impact of H<sub>2</sub>S and converting it into electric power.</p> </div><p></p><h2>Other Information</h2> <p> Published in: Energy Technology<br> License: <a href="http://creativecommons.org/licenses/by/4.0/" target="_blank">http://creativecommons.org/licenses/by/4.0/</a><br>See article on publisher's website: <a href="http://dx.doi.org/10.1002/ente.202000531" target="_blank">http://dx.doi.org/10.1002/ente.202000531</a></p> |
