“…CFD treatments are well suited to simulating three-dimensional flow characteristics through complex non-porous structures such as the flow fields of a fuel cell bi-polar plate (BPP) [16], flow through porous regions on a volume-averaged basis [17,18,19] and planar temperature and current density distributions across the surface of the PEFC [20,21]. CFD treatments are not well-suited to simulating electrochemical cross-flow through quasi-porous layers, effects of layer compression/expansion/constraint as this invokes dynamic boundaries, or again flow through actual heterogeneous porous structures of PEFC layers…”

This research reports a feasibility study into multi-scale polymer electrolyte fuel cell (PEFC) modelling through the simulation of macroscopic flow in the multi-layered cell via 1D electrochemical modelling, and the simulation of microscopic flow in the cathode gas diffusion layer (GDL) via 3D single-phase multi-component lattice Boltzmann (SPMC-LB) modelling. The heterogeneous porous geometry of the carbon-paper GDL is digitally reconstructed for the SPMC-LB model using X-ray computer micro-tomography. Boundary conditions at the channel and catalyst layer interfaces for the SPMC-LB simulations such as specie partial pressures and through-plane flow rates are determined using the validated 1D electrochemical model, which is based on the general transport equation (GTE) and volume-averaged structural properties of the GDL. The calculated pressure profiles from the two models are cross-validated to verify the SPMC-LB technique. The simulations reveal a maximum difference of 2.4% between the thickness-averaged pressures calculated by the two techniques, which is attributable to the actual heterogeneity of the porous GDL structure.

“…In such a way, different levels of approximation for the estimation of the local electrochemical kinetics are available. Neglecting here micro-and mesoscopic levels [26], the more accurate approach traditionally consists of detailed numerical simulation tools [7,8,11,16,21,27], which can be heavy to handle when commercial size cells or stack are considered. Advanced analytical studies have also been recently proposed, such as the fractal approach [28], which are useful to assess the main relationships which rule phenomena and influence performance.…”

Gas-Phase Mass-Transfer Resistances at Polymeric Electrolyte Membrane Fuel Cells Electrodes: Theoretical Analysis on the Effectiveness of Interdigitated and Serpentine Flow Arrangements

Mass transfer phenomena in polymeric electrolyte membrane fuel cells (PEMFC) electrodes has already been analyzed in terms of the interactions between diffusive and forced flows. It was demonstrated that the whole phenomenon could be summarized by expressing the Sherwood number as a function of the Peclet number. The dependence of Sherwood number on Peclet one Sh(Pe) function, which was initially deduced by determining three different flow regimes, has now been given a more accurate description. A comparison between the approximate and the accurate results for a reference condition of diluted reactant and limit current has shown that the former are useful for rapid, preliminary calculations. However, a more precise and reliable estimation of the Sherwood number is worth attention, as it provides a detailed description of the electrochemical kinetics and allows a reliable comparison of the various geometrical arrangements used for the distribution of the reactants.

“…A complete PEMFC system model was developed by Pathapati et al [5] which included the dynamics of flow and pressure in the channels. Hu et al [6] represented a threedimensional computational PEM fuel cell model with comparison of different flow fields. In recent years, several improved models were published by Park and Choe [7] and Jia et al [8] to investigate fuel cell transient electrical responses under various operating conditions.…”
