Anaerobic Digestion (AD) is used worldwide for treating organic waste and wastewater. Biogas produced can be converted using conventional energy conversion devices to provide efficient, integrated solutions. Typically, the electrical conversion-efficiency of these 30–40% lowered due biogas utilization instead high pure refined natural gas. The Solid Oxide Fuel Cell (SOFC) as an alternative device offers (50–60%) efficiency with low emissions (CO2, NOx) temperature residual heat. quality heat...
Biogas is known as a traditional energy source for off-grid population throughout the world. And currently small-scale solid oxide fuel cell (SOFC) systems are being promoted supply. Also, electricity demand increasing at high rate due to ever-increasing and technological revolution. Therefore, promotion of supply needs be refocused. The small scale biogas-SOFC an envisaged modern system which can meet both thermal electrical more efficiently (60% 800 °C) than available technologies....
Solid oxide fuel cell (SOFC) technology offers a clean and efficient way to generate electricity from natural gas. Since various integration options with thermal cycles have been proposed achieve even higher electrical efficiencies, it is interesting see how these compare. In addition, the influence of SOFC operating parameters on not yet adequately addressed. this study, stand-alone system thermodynamically analysed compared configurations combined gas turbine or steam turbine, as well...
An increasing demand in the marine industry to reduce emissions led investigations into more efficient power conversion using fuels with sustainable production pathways. Solid Oxide Fuel Cells (SOFCs) are under consideration for long-range shipping, because of its high efficiency, low pollutant emissions, and fuel flexibility. SOFC systems also have great potential cater heat ships, but integration is not often considered when assessing feasibility. This study evaluates electrical efficiency...

Direct internal reforming enables optimal heat integration and reduced complexity in solid oxide fuel cell (SOFC) systems, but thermal stresses induced by the increased temperature gradients may inflict damage to stack. Therefore, development of adequate control strategies requires models that can accurately predict profiles A 1D dynamic modelling platform is developed this study, used simulate SOFCs both single stack configurations. The model validate power law Hougen-Watson kinetics...
Various concepts have been proposed to use hydrocarbon fuels in solid oxide fuel cell (SOFC) systems. A combination of either allothermal or adiabatic pre-reforming and water recirculation (WR) anode off-gas (AOGR) is commonly used convert the into a hydrogen rich mixture before it electrochemically oxidised SOFC.
