Hydrogen sulfide (H2S) is an abundantly present, corrosive, and noxious compound. Though the Claus process is effective in processing H2S, it extracts minimal energy from H2S. Solid oxide fuel cell (SOFC) can harvest the chemical energy of H2S to generate electric power. For practical implementations, the performance of H2S/air SOFCs and the potential losses in the system are determined. The present study aims to develop the complete electrochemical model of H2S/air SOFC system and to analyze its performance. The theoretical cell potential of H2S/air SOFC is determined, and the deviations from the theoretical cell potential due to polarization are studied. According to the results, H2S/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 SO2 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 H2S/air SOFC to serve as a basis for the implementation of H2S/air SOFC toward eliminating the environmental impact of H2S and converting it into electric power.

“…Today, H 2 S concentrations in the developed natural gas reserves can reach as high as 25 vol%, for example, in Astrakhan, Tengiz. [ 3 ] It is anticipated that the processing of H 2 S‐rich natural gas reserves will further increase with mastering of deep gas deposits since it is known that the H 2 S concentration increases with depth.…”

Summary Catalytic operations, achieving considerable energy savings, continue getting wider application especially in clean energy systems. Perovskite materials, owing to their chemical and thermal stability, can be conveniently used as catalysts and electrode materials at wide temperature ranges. Hydrogen sulfide (H2S) offers a new and abundant source of hydrogen, the ultimate energy carrier. In the present work, change in electrical conductivity of catalysts obtained by adding molybdenum (Mo) and vanadium (V) as B to the perovskite structure with lanthanum (La) and strontium (Sr) as A and A′, respectively, has been studied within a temperature range of up to 1100 K. Samples La0.75Sr0.25MoO3 and LaSr0.5V0.5O3 demonstrated the highest values of conductivity at 1100 K. At lower temperatures, Cr‐added Mo and V catalysts La0.9Sr0.1Cr0.5Mo0.5O3 and La0.9Sr0.1Cr0.5V0.5O3 had higher conductivity, closely followed by LaSr0.5V0.5O3.
