abstract = {For this study, gas transport in the gas diffusion layers
of polymer electrolyte fuel cells was analyzed in one
through-plane and two in-plane directions. Gas transport was
calculated using Lattice Boltzmann simulations, with
non-woven gas diffusion layers measured both through-plane
and in-plane. The micro structure for the transport
simulations was based on a stochastic model that can take
into account uncompressed and compressed materials. The
micro structure of this kind of gas diffusion layers is
superposed by fiber bundles. Their impact on the anisotropy
of the in-plane permeabilities was then investigated.
Finally, the influence of structural inhomogeneities on
in-plane flow was analyzed. Compression has a high influence
on through-plane and in-plane permeability. The impact of
the fibers bundles is smaller than the impact of local
variations of the micro structure according to the
stochastic geometry model.},
