Modeling solid oxide fuel cell operation: Approaches, techniques and results

Modelling of a solid oxide fuel cell for integrated coal gasification hybrid power plant simulation

“…A literature review of modelling work with steady state and zero-dimensional resolution can be found elsewhere [40][41][42]. In the following, analytical and semi-empirical models are described briefly.…”

Three dimensional modeling of an solid oxide fuel cell coupling charge transfer phenomena with transport processes and heat generation

“…The physics of laminar and turbulent incompressible flow are well described by the Navier-Stokes equation, and it is common practice to assume laminar flow for fuel cell gas channels due to the low velocities, which decreases the computational cost significantly [43]. The Darcy equation describes the balance between the force from the pressure gradient and the frictional resistance from the (porous) solid material.…”

Advanced Power Generation Technologies: Fuel Cells

“…Understanding the internal physics and chemistry of fuel cells are often difficult. This is due to the great number of physical and chemical processes in the fuel cells, difficulty in independent controlling of the fuel cell parameters, and access limitations to inside of the fuel cells (Bove & Ubertini, 2006). In addition, fuel cells simulation can help to focus experimental research and to improve accuracy of interpolations and extrapolations of the results.…”

“…This problem can be intensified for new researchers as they can be easily overwhelmed by this sheer volume of resources. That is why there have been many review papers on the modeling of different types of fuel cells, especially for modeling and simulation of PEFC (Biyikoglu, 2005;Haraldsson & Wipke, 2004;Sousa & Gonzalez, 2005;Tao et al, 2006;Young, 2007;Wang, 2004), SOFC (Young, 2007;Wang, 2004;Kakac et al, 2007;Bove & Ubertini, 2006) and to a lesser extent MCFC (Baker, 1984). As mentioned previously, although both SOFC and MCFC can be used in hybrid cycles, due to the cell reactions and the molten nature of the electrolyte and lower efficiency of MCFC (Song et al, 2005), vast majority of research in this field are in SOFC hybrid cycles.…”

“…Therefore, in order to extract these governing equations, high level of assumptions and simplifications should be considered which in turn introduce inaccuracy to the final results. This means fuel cell models are a "simplified representation of real physics" and even with appropriate validation, accuracy of their results cannot be guaranteed (Bove & Ubertini, 2006). For instance, one should be aware of the possible problems that can arise when local equations are considered as global.…”
