Crosslinked sulfonated polyphenylenes: Overcoming the performance – gas permeation – stability trilemma in Water Electrolyzers

Abstract

Thermal crosslinking of Pemion®, a highly sulfonated polyphenylene membrane, is used as a viable route to combine high proton conductivity, low gas permeability and mechanical robustness. Crosslinked Pemion® not only outperforms any other membrane reported so far, as a PFAS-free membrane, it is also considered to be environmentally more benign.
