      abstract     = {Differential pressure electrolysis offers the potential for
                      more efficient hydrogen compression. Due to the differential
                      pressures acting within the electrolytic cell, the porous
                      transport layer (PTL) is subjected to high stress. For
                      safety reasons, the PTL's mechanical stability must be
                      ensured. However, the requirements for high porosity and low
                      thickness stand in contrast to that for mechanical
                      stability. Porous transport layers for polymer electrolyte
                      membrane (PEM) electrolysis are typically prepared by means
                      of the thermal sintering of titanium powder. Thus far, the
                      factors that influence the mechanical strength of the
                      sintered bodies and how all requirements can be
                      simultaneously fulfilled have not been investigated. Here,
                      the static and dynamic mechanical properties of thin
                      sintered titanium sheets are investigated ex-situ via
                      tensile tests and periodic loading in a test cell,
                      respectively. In order for a sintered PTL with a thickness
                      of 500 μm and porosities above $25\%$ to be able to
                      withstand 50 bar differential pressure in the cell, the
                      maximum flow field width should be limited to 3 mm. Thus, a
                      method was developed to test the suitability of PTL
                      materials for use in electrolysis for various differential
                      pressures and flow field widths.},
