PFSA Ionomers as PEM Electrolyzer Membranes

17 October 2023 by Chingis Idrissov
Proton exchange membranes are made of perfluorinated sulfonic-acid (PFSA) ionomers. These membranes are a key component of the proton exchange membrane electrolyzers (PEMELs) as well as fuel cells (PEMFCs). This premium article provides an overview of the application of PFSA membranes in PEMELs, with discussion of the key players, pros & cons, production methods and key recent innovations within the space.
