abstract = {The use of decal substrates to produce catalyst coated
membranes (CCMs) for polymer electrolyte membrane water
electrolyzers or fuel cells is a common procedure. For
economic and ecological reasons, the reuse of decal
substrates would be desirable. Thus far, it has not been
investigated whether reuse is possible. Therefore, this
study focuses on the repeated coating and transfer in decal
processes and investigates changes in substrate properties.
After coating Kapton and PTFE with a Carbon-Nafion
dispersion, the dry layer was transferred onto a Nafion
membrane. This procedure was repeated 50 times. The change
in substrate thickness and surface free energy (SFE), as
well as the transfer rate (TR), were monitored. The residues
on the substrate and scattering of the TR were higher for
Kapton compared to PTFE. None of the decal substrates
changed its SFE and thickness within the measurement
uncertainties. Because of the smaller scattering in the TR,
PTFE is more suitable for reuse.},
