Used as a proton exchange membrane in fuel cells, enabling efficient conversion of chemical energy into electrical energy. Commonly applied in hydrogen fuel cells for vehicles and portable power systems due to its excellent proton conductivity and chemical stability.

Widely used in electrolysis systems, particularly for water splitting to produce hydrogen and oxygen, thanks to its ability to withstand harsh acidic environments.

Serves as a catalyst support in electrochemical reactions, enhancing performance and durability of catalysts in industrial processes.

Employed in sensors and electrochemical devices where reliable proton conduction is required under varying temperature and humidity conditions.

Used in chlor-alkali cells as a selective membrane to separate chlorine and sodium hydroxide production, improving efficiency and purity in industrial chemical manufacturing.
