Internal dry reforming of methane is envisaged as a possibility to reduce on capital and operation costs biogas fuelled solid oxide fuel cells (SOFCs) system by using the CO2 present in biogas. Due internal reforming, requirement for upgrading becomes obsolete, thereby simplifying complexity increasing its technology readiness level. However, impurities prevailing such H2S have been reported li...
A detailed model is presented for the analysis of temperature, species concentration, and current density profiles as well as the efficiency and power density of a planar solid oxide fuel cell at direct internal reforming condition. The model describes the interactions of mass transport, heat transport, heterogeneous chemistry, and electrochemistry. The heterogeneous chemistry model for the cat...
In this study, a solid oxide fuel cell (SOFC) stack has been successfully fabricated and tested by using direct natural gas. The main objective of this research was to achieve optimal long-term performance of the SOFC stack without carbon deposition by using low-cost natural gas as a fuel. The stack configuration was improved by a new interconnect design and made of cost-effective raw materials...
Two novel system configurations were proposed for oxy-fuel natural gas turbine systems with integrated steam reforming and CO2 capture and separation. The steam reforming heat is obtained from the available turbine exhaust heat, and the produced syngas is used as fuel with oxygen as the oxidizer. Internal combustion is used, which allows a very high heat input temperature. Moreover, the turbine...
