A micro-structured electrochemical membrane reactor with a proton-conducting ceramic membrane is considered for processing gaseous H2S diluted (1 vol.%) in H2O mixtures. Y-doped barium zirconate (BaZr0.85Y0.15O3−δ) is employed as solid electrolyte. Ceria supported transition metal (Co, Ni, Fe, Cu) catalysts and LaCrO3 composites are explored as anode materials and La0.6Sr0.4Co0.2Fe0.8O3−δ perovskite type oxides are used as cathode electrodes. Preliminary results concern materials preparation and characterization of the catalytic performance of anodic electrode materials. Co/CeO2 composites show excellent H2S conversion and stability performance in wet and dry atmospheres at 873–1123 K. Presence of water has a beneficial effect on the H2 formation, in accordance with thermodynamics. The overall process starting from H2S containing sea water to H2 generation in the membrane reactor and H2SO4 production in a sequential step is simulated and its energy balance is discussed. http://creativecommons.org/licenses/by-nc-nd/4.0/13th International Conference on Clean Energy Ipsakis D.
