Syensqo and Johnson Matthey demonstrate recovery and reuse of platinum-group metals from fuel-cell and electroyzer components

Syensqo (Brussels) and Johnson Matthey (London) have demonstrated a viable process to recover and reuse platinum-group metals (PGMs) and ionomers from PEM fuel-cell and electrolyzer components without compromising performance. According to a new joint white paper, they achieved kilogram-scale recovery from industrial materials, pointing to a scalable, circular pathway that could cut costs and environmental impact for hydrogen technologies.

What barriers—technical, economic, or policy—most need to be addressed to scale closed-loop recycling of PGMs and ionomers across the fuel-cell and electrolyzer supply chain?
