Details

This product is a perfluorinated sulfonic acid membrane from DuPont, designed for use as a solid electrolyte separator in fuel cells and related electrochemical devices. The Nafion 117 membrane offers a balance of high proton conductivity (0.083 S/cm) and mechanical robustness, with a thickness of 183 µm and an ion exchange capacity of 0.89 meq/g. It exhibits excellent thermal stability, resistance to chemical oxidation, and long operational life, making it suitable for demanding applications such as proton exchange membrane fuel cells, vanadium redox flow batteries, electrolyzers, electrodialysis cells, and electrochemical sensors. The membrane can be pre-treated with hydrogen peroxide and dilute sulfuric acid to optimize performance, or conditioned directly in electrolyte solutions per user protocols. Available in 10 cm × 10 cm and 30 cm × 30 cm sizes, it is a widely used reference material in energy research and experimental fuel cell setups.

This product is used in the production of fuel cells. N117 film can be pre-treated before use, the specific method is as follows: first, treat with 5% hydrogen peroxide in 80 degrees Celsius for 1 hour, then soak in deionized water for half an hour; then boil with 5% dilute sulfuric acid (mass ratio) at 80 degrees Celsius for 1 hour; finally, soak in deionized water for half an hour, and it is ready for use.

Alternatively, it can also be used by soaking in an electrolyte solution according to user's established habit.
