The assessment of the contribution of short-term wind power predictions to the efficiency of stand-alone hybrid systems
Tascikaraoglu, A.; Uzunoglu, M.; Vural, B. - In: Applied Energy 94 (2012) C, pp. 156-165
Distribution of electricity to the rural areas, particularly in regions which have rough topography causes high costs and losses. Hybrid systems can provide electricity at a relatively economic price at these regions. This paper designs and tests a stand-alone hybrid system combining variable...

Modeling and Analysis of Transport Processes and Efficiency of Combined SOFC and PEMFC Systems
Rabbani, Abid; Rokni, Masoud - In: Energies 7 (2014) 9, pp. 5502-5522
A hybrid fuel cell system (~10 kWe) for an average family house including heating is proposed. The investigated system comprises a Solid Oxide Fuel Cell (SOFC) on top of a Polymer Electrolyte Fuel Cell (PEFC). Hydrogen produced from the off-gases of the SOFC can be fed directly to the PEFC....

Thermodynamic analysis of SOFC (solid oxide fuel cell)–Stirling hybrid plants using alternative fuels
Rokni, Masoud - In: Energy 61 (2013) C, pp. 87-97
A novel hybrid power system (∼10 kW) for an average family home is proposed. The system investigated contains a solid oxide fuel cell (SOFC) on top of a Stirling engine. The off-gases produced in the SOFC cycle are fed to a bottoming Stirling engine, at which additional power is generated....
