...Adrian Dumitrescu; T. W. Lee; R. P. Roy A computational model of a hybrid pressurized solid oxide fuel cell (PSOFC) generator/gas turbine power plant is developed using classical thermodynamic analysis in conjunction with electromechanical, fluid-mechanical, and heat transfer simulations...

...Adriano Sciacovelli; Vittorio Verda The aim of the paper is to investigate possible design modifications in tubular solid oxide fuel cell geometry to increase its performance. The analysis of the cell performances is conducted on the basis of the entropy generation. The use of this technique makes...

...Ibrahim Dincer; Marc A. Rosen; Calin Zamfirescu Energy and exergy assessments are reported of integrated power generation using solid oxide fuel cells (SOFCs) with internal reforming and a gas turbine cycle. The gas turbine inlet temperature is fixed at 1573 K and the high-temperature turbine...

...Wei Jiang; Ruixian Fang; Roger A. Dougal; Jamil A. Khan A one-dimensional transient model of a tubular solid oxide fuel cell stack is proposed in this paper. The model developed in the virtual test bed ( VTB ) computational environment is capable of dynamic system simulation. This model is based...

...Andrea Lazzaretto; Andrea Toffolo; Federico Zanon Several empirical assumptions deriving from observations and measurements of the physical processes are involved in the modeling of Solid Oxide Fuel Cells (SOFCs). An insight of the main models proposed in the literature is given to present...

...) are limited indices-of- merit. Contemporary second law concepts (availability/exergy, irreversibility, exergetic efficiency) have been used to enhance fuel cell evaluation. A previously modeled solid oxide fuel cell has been analyzed using both conventional measures and the contemporary thermodynamic measures...
