      abstract     = {During the clamping of a Fuel Cell, the porosity of the gas
                      diffusion layer (GDL) and the contact resistances are
                      continuously reduced. In this work, the optimum clamping
                      pressure is determined for three commonly used GDLs. For
                      this purpose, polarization curves are recorded for contact
                      pressures of 0.1–2.7 N/mm2. For the SGL 29BCE material,
                      the optimum contact pressure range is very narrow, while the
                      Toray TGP-H 060 material performs best in a wider range; the
                      Freudenberg H2315 material is the most robust type, and
                      works best from 0.6 N/mm2 until the maximum (2.7 N/mm2). For
                      the understanding of the mechanical effects on the GDL
                      structure, scanning electron microscopy and nano-computer
                      tomography images are made. In addition, permeability
                      measurements are carried out. To transfer the results, the
                      local pressure distributions are recorded, and their minima
                      and maxima are considered. Ultimately, this information
                      allows the transfer of the results to other flow field
                      geometries.},
