      abstract     = {In polymer electrolyte fuel cells of the types PEFC, DMFC
                      and HT-PEFC, the gas diffusion layer (GDL) connects the
                      electrodes with the feeding channels of the bipolar plate.
                      The GDL is typically composed of materials based on carbon
                      fibers, e.g., paper, woven or non-woven textiles. Efficient
                      fuel cell operation requires that the electrodes are
                      sufficiently supplied by gaseous fluids from the channels.
                      Also, reaction products must be transported away from the
                      electrodes. The GDL also has to provide electronic contact
                      to the bipolar plates, but its major task is the mass
                      transport of fluids. The gas transport in through-plane
                      direction is simulated in the porous structure of the GDL,
                      represented by stochastic geometries equivalent to the real
                      structure. In order to support multi-scale simulation,
                      effective properties can be calculated from these mesoscale
                      simulation results to provide model parameters for continuum
                      approaches in cell-scale simulations. In this paper, the
                      resulting gas flow is analyzed with statistical methods with
                      the focus on the interface between GDL and electrode. This
                      approach provides the opportunity to detect quantitative
                      relationships between functionality and microstructure and
                      to design virtual GDL materials with improved transport
                      properties. The evaluation of the interface with stochastic
                      methods provides substantiated properties suitable for
                      connecting regions representing fuel cell components of
                      different spatial scales},
