Performance modeling and parametric investigation of a solid oxide fuel cell (SOFC)
In his paper, performance modeling and parametric study of a tubular solid oxide fuel cell (SOFC) fed by hydrogen was conducted. The components of the fuel cell system and its reactions were entirely modelled and an electrochemical analysis done for it. A variety of modeling parameters including temperature, working pressure and the air mass- flow rate have been investigated in order to observe...
متن کاملExergetic Optimization on Solid Oxide Fuel Cell Systems
Biogas can be currently considered as an alternative option for electricity production, mainly due to its high energy content (hydrocarbon-rich source), its renewable status and its relatively low utilization cost. Solid Oxide Fuel Cell (SOFC) stacks convert fuel’s chemical energy to electricity with high efficiencies and reveal significant advantages on fuel flexibility combined with lower emi...
متن کاملModeling the Performance of a Tubular Solid Oxide Fuel Cell
In this paper, we develop two computational models for the electrical performance of the tubular solid oxide fuel cell designed by Siemens Westinghouse Corporation. The first model makes simplifying assumptions for activation and concentration polarizations and obtains an analytical solution. In the second procedure, we allow the polarizations to vary with the current density and solve the equa...
متن کاملThree-dimensional modeling of transport phenomena in a planar anode-supported solid oxide fuel cell
In this article three dimensional modeling of a planar solid oxide fuel cell (SOFC) was investigated. The main objective was to attain the optimized cell operation. SOFC operation simulation involves a large number of parameters, complicated equations, (mostly partial differential equations), and a sophisticated simulation technique; hence, a finite element method (FEM) multiphysics approach ...
متن کاملLattice Boltzmann modeling of two component gas diffusion in solid oxide fuel cell
In recent years, the need for high efficiency and low emission power generation systems has made much attention to the use of fuel cell technology. The solid oxide fuel cells due to their high operating temperature (800 ℃ -1000 ℃) are suitable for power generation systems.Two-component gas flow (H2 and H2O) in the porous media of solid oxide fuel cell’s anode have been modeled via lattice Boltz...
