Perfluorinated sulfonic acid (PFSA) ionomers have been widely used for both membrane and electrode binder materials in galvanic and electrolytic cell applications owing to their proton transport capability and chemical durability. For advanced electrochemical applications, the gas permeation properties of the PFSA ionomers are needed to be tailored, maintaining their identical chemical architectures for the formation of stable interface between membrane and electrode layers. PFSA membranes should prevent gas crossover as much as possible, while PFSA electrode binders must have low resistance to gas passage. In this study, ionomer size engineering is conducted in benign solvent atmospheres via supercritical fluid dispersion techniques. |
