NemudryAbstractAC heated oxygen-permeable microtubular membranes with the composition Ba0.5Sr0.5Co0.78W0.02Fe0.2O3-δ were used to provide catalytic reforming of methane into C2- hydrocarbons. The methane conversion degree about 60% and acetylene yield about 27% at 1200 °C was achieved. Microtubular solid oxide fuel cells based on gadolinium-doped ceria with perovskite-like cathode material composed of Ba0.5Sr0.5Co0.75Mo0.05Fe0.2O3-δ were prepared. The MT-SOFC demonstrates maximum power densities of 50, 100, 200 mW/cm2 at 550, 600, 650 °C, respectively with humidified H2 as fuel and ambient air as oxidant.Graphical Abstract
