“…With this method it is possible to incorporate complex spatial structures in the simulation domain. The features of the method range from single phase, single component flow [16,17] to multi component [18,19,20,21] and/or multi phase configurations [18,22,23,24]. Sophisticated data structures and algorithms can be included [25,26] as well as extended boundary conditions [27,22,28].…”

In this paper we combine a stochastic 3D microstructure model of a fiber based gas diffusion layer of polymer electrolyte fuel cells with a Lattice Boltzmann model for fluid transport. We focus on a simple approach of compressing the planar oriented virtual geometry of paper-type gas diffusion layer from Toray. Material parameters -permeability and tortuosity -are calculated from simulation of one phase, one component gas flow in stochastic geometries. We analyze the statistical spread of simulation results on ensembles of the virtual geometry, both uncompressed and compressed. The influence of the compression is discussed with regard to the Kozeny-Carman equation. The effective transport properties calculated from transport simulations in compressed gas diffusion layers agree well with a trend based on the Kozeny-Carman equation.

“…However, Khan et al [1] has questioned the validity of this assumption and highlighted that even fractional difference in temperature could have significant effects, which infers that several other unknown factors might influence the evaporation/condensation process. These unknown factors are accounted for through the condensation factor K c in the simulation.…”

“…In order for this to happen a thorough understanding of transport of species through flow channels, gas diffusion layers, electrochemical reactions at catalyst layers, charge transports, heat transport and phase change of water is required. Due to confined and highly reactive nature of fuel cell, experimental data of common parameters such as temperature, species distribution, pressure and saturation within a fuel cell is sadly lacking [1]. In this respect a computational fluid dynamics model can provide a great deal of insight into the processes and phenomena inside a PEM fuel.…”

“…With the advancement of knowledge and computer power, the recent trend has been to employ three dimensional, two-phase modeling. Khan et al [1] have provided a recent review on two-phase flow modelling of PEM fuel cell and highlighted that anisotropic GDL properties, water saturation and inter-phase change between humidified gaseous species and liquid water are still less understood.…”

“…Meng [12] developed a mixed domain two-fluid PEM fuel cell model, where water transport through the membrane was calculated by solving a conservation equation for the water content in the membrane. Further details in two-phase modelling of PEM fuel cell can be found in the recent review paper by Khan et al [13].…”

A definitive version was subsequently published in Renewable Energy, [VOL 50 (2013) AbstractThe present study focuses on the investigation of water dynamics inside a polymer electrolyte membrane fuel cell using two different modelling approaches: Eulerian two-phase mixture and volume of fluid interface tracking models. The Eulerian twophase mixture model has provided overall information of species distribution inside a fuel cell and identified that the liquid water usually accumulates under the land area.
