Effective diffusivity in partially-saturated carbon-fiber gas diffusion layers: effect of through-plane saturation distribution
TL;DR: In this article, the effective diffusivity of carbon-fiber gas diffusion layers (GDLs) used in polymer electrolyte fuel cells (PEFCs) was determined by performing lattice Boltzmann (LB) simulations on X-ray tomographic reconstructions of invading water configurations.
Journal ArticleDOI
Nonlinear orthotropic model of the inhomogeneous assembly compression of PEM fuel cell gas diffusion layers
TL;DR: In this article, a finite element model was proposed to model the nonlinear orthotropic properties of the gas diffusion layer (GDL) in a PEM fuel cell, and the numerical results showed that the linear isotropic models widely reported in the literature tend to overestimate the porosity and the partial intrusion of the GDL in the channel region.
Journal ArticleDOI
Effective diffusivity in partially-saturated carbon-fiber gas diffusion layers: Effect of local saturation and application to macroscopic continuum models
TL;DR: In this article, lattice Boltzmann simulations were performed on tomographic images of dry and water-invaded carbon-paper GDL subsamples with nearly uniform porosity and saturation distributions.
Journal ArticleDOI
Analysis of representative elementary volume and through-plane regional characteristics of carbon-fiber papers: diffusivity, permeability and electrical/thermal conductivity
Pablo A. García-Salaberri,Iryna V. Zenyuk,Andrew Shum,Gisuk Hwang,Marcos Vera,Adam Z. Weber,Jeff T. Gostick +6 more
TL;DR: In this paper, the existence of a representative elementary volume (REV) in CFPs is assessed in terms of dry effective transport properties: mass diffusivity, permeability and electrical/thermal conductivity.
Journal ArticleDOI
Ignition, Liftoff, and Extinction of Gaseous Diffusion Flames
TL;DR: In this article, a review of the fluid dynamics of non-premixed combustion is presented, including diffusion-controlled flames, edge flames, triple flames and their role as ignition fronts, and flame-vortex interactions.
