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.

Sulfonated poly(sulfone-pyridine-amide)/sulfonated polystyrene/multiwalled carbon nanotube-based fuel cell membranes

Perfluorosulfonic acid (PFSA) membranes, the best known example of which, is DuPont Nafion, are most widely used as the electrolyte in fuel cell research.

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."

BCC Report Examines MEAs for PEM Fuel Cells

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.

Fuel cell membranes

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.
