abstract = {We report the development of a facile recycling process for
catalyst coated membranes (CCMs) used in polymer electrolyte
membrane (PEM) water electrolyzers. After performance
evaluation in an assembled electrolysis cell,
ultrasonication is used to provide high-yield recovery of
not only the noble-metal catalyst materials, but also of the
fluoropolymer membrane itself, without the release of
hazardous gases. Transmission electron microscopy (TEM) and
electrochemical characterization are used to confirm the
retention of catalyst particle size, and of the performance
of the recycled CCMs. Furthermore, our projections indicate
that, if this approach is widely employed, existing
resources of noble metals will prove sufficient for the
gigawatt-scale implementation of PEM water electrolyzers.
This has profound implications for the achievement of
current targets for reducing the consumption of precious
metals for applications in electrolyzers, fuel cells and
other energy storage devices.},
