    Photograph and schematic lay-out of the experimental setup, featuring an improved flow field design and a reduced thickness of the graphite window (500 µm). The latter is transparent to X-rays at the K edge energies (6 8 keV) of transition metal catalysts such as manganese, iron, cobalt and nickel. The improved cell design therefore also enables operando XAS studies of commonly investigated fuel cell catalysts based on these 3d transition metal alloys with platinum, or of PGM-free iron-based catalysts.
