In this study, an electricity and value-added chemicals cogeneration system using methane-fueled single chamber solid oxide fuel cells (SC-SOFCs) was successfully developed and investigated. The SC-SOFCs, which operated on methane/oxygen gas mixture with a ratio of 2:1, achieved an open-circuit voltage of 1.0 V and a maximum peak power density of ∼ 840 at 700 °C. By passing the exhaust gas of the fuel cell through a Ru/Al2O3 catalyst at 700 °C, the synthesis gas is obtained with a methane conversion of higher than 95%, while CO and H2 selectivity is higher than 92%. This study provides a novel strategy for energy conversion which is one of the major concerns in energy field and a new frontier for improving the energy efficiency of SOFCs.
