abstract = {Electrodes for polymer electrolyte membrane electrolyzers
and fuel cells are manufactured by coating a catalyst
dispersion, consisting of precious metal, ionomer and
solvents, onto a substrate that is subsequently dried. One
target of current research is to produce square meter-sized
electrodes, but so far the homogeneity that can be achieved
in this scaling is unclear. To quantify the achievable
homogeneity of an electrode, manufactured by means of slot
die coating in a roll-to-roll pilot plant, this study
focuses first on the selection of an appropriate substrate
by investigating thickness, basis weight and surface free
energy distribution at the square meter scale. Afterward, a
dispersion is coated on the selected substrate, dried and
investigated with respect to thickness and basis weight
distribution. Among the investigated substrates, Kapton has
the smallest scatter in terms of thickness and basis weight.
The subsequent coating results in a precious metal loading
of 1.10 mg cm−2, with a scattering of $5.5\%$ that can be
further reduced to $4.5\%$ when edge effects can be
prevented. These results are now available for further
research in which it is necessary to investigate whether or
not these fluctuations affect the achievable electrochemical
efficiencies of electrodes.},
