                      few micrometers was applied to study transport processes
                      within a Proton Exchange Membrane (PEM) electrolyzer cell.
                      The degradation process of the catalyst layer, gas
                      production with bubble formation at the catalyst layer and
                      in the porous transport layer (PTL) was analyzed. From this,
                      a new cell design was developed that allows for high X‐ray
                      transmittances at the membrane plane in the in‐plane
                      viewing direction. During the measurement, a bubble growth
                      and movement was observed. Furthermore, a detachment of
                      catalytic material from the catalyst layer was detected.
                      Afterwards, a post mortem EDX analysis was conducted to
                      determine the position of the catalyst particles. Despite
                      Iridium being initially used as the anode catalyst and
                      platinum as the cathode catalyst, the EDX measurement
                      revealed Pt and Ir particles on both electrodes following
                      cell operation.},
