This study explores the use of Ba0.5Sr0.5Co0.8Fe0.2O3-δ (BSCF) membranes for pure hydrogen production via water splitting. The membrane was coated with a BaCe0.2Fe0.8O3-δ catalyst to activate the water splitting reaction in a membrane reactor. H2O/Ar and CH4/Ar gas mixtures were supplied to the feed and sweep sides, respectively. Exit gases were analysed in situ using micro-GC. The results revealed that the hydrogen production rate increased with increasing temperature, methane, and water concentrations. The highest hydrogen production rate (0.37 µmol/cm2s) was achieved at 925 °C using 15% CH4 in the sweep and 55% H2O in the feed. On the sweep side, CH4 reacts to generate CO2 and syngas (H2 + CO) in a ratio commonly used in integrated gasification combined cycle power plants. This study highlights the potential of BSCF membranes as a promising technology for simultaneous production of pure hydrogen, on one side, and syngas through controlled reactions involving methane and permeated oxygen, on the other side.
