However, high cost, low glass-transition temperature, high gas permeability, fuel different from pure hydrogen, and environmental incompatibility have been issues for the perfluorosulfonic Acid (PFSA) membranes that limit their further applications.
The fastest growth overall for fluoropolymers will be in smaller-volume resins, such as perfluoroalkoxy (PFA) polymers, polyvinyl fluoride (PVF) films, and perfluorosulfonic acid polymers.
BCC also noted that while perfluorosulfonic acid polymers "and their close relatives" currently dominate the membrane market for PEM fuel cells, other materials may become useful in the near future, including sulfonated hydrocarbons, heterocyclics such as polybenzimidazole (PBI) and "their related polymers and esters modified.

Perfluorosulfonic acid membranes, the best known example of which is DuPont's Nafion, are most widely used in fuel cells because of their high proton conductivity, high chemical stability and excellent mechanical properties.
A typical membrane is based on a perfluorosulfonic acid ionomer.
Nowadays, hydrated perfluorosulfonic acid membranes, such as Dupont's Nafion, are typically used as the polymer electrolytes in hydrogen/oxygen polymer electrolyte membrane (PEM) fuel cells because of their excellent chemical and mechanical stability, as well as high proton conductivity.
