Johnson Matthey (JM) and Syensqo have successfully demonstrated a pilot-scale process for the recovery of precious metals and ionomers from PEM fuel cell and electrolyser components. The method allows for the recycling of platinum group metals (PGMs) and ionomers from catalyst-coated membranes (CCMs) without incineration.

Analysis indicates the recovered ionomer meets original specifications and shows equivalent proton conductivity to fresh material. The companies assert that their approach could reduce carbon footprints by up to 80%, contributing to a more circular PEM ecosystem. The recovery process addresses industry concerns regarding the scarcity of PGMs and regulatory pressures on PFAS materials.
