General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Find details here.

Application

Nafion™ is a perfluorinated ion-exchange membrane which has a wide variety of commercial uses. The acidic (hydrogen ion) form and derivatives are solid, superacid catalysts useful in a wide variety of synthetic applications.
Nafion™ perfluorinated membrane (Nafion 117) is a composite material that can be used as an electrolytic ion-exchange membrane for the fabrication of fuel cells.

Packaging

Darkening/browning is common for pieces stored in a general room environment for an extended period of time (several months), due to organics pick-up. Verify product is kept sealed during storage.
  • Keep pieces sealed and protected from general exposure will reduce the effect. Recommend long term storage in air-tight bags.
  • Discoloration does not affect performance and can be removed by soaking in dilute nitric acid.

Materials Issues in Polymer Electrolyte Membrane Fuel Cells

Fuel cells have the potential to reduce the nation’s energy use through increased energy conversion efficiency and dependence on imported petroleum by the use of hydrogen from renewable resources.

Proton Exchange Membrane (PEM) Fuel Cells

Proton exchange membrane (PEM) fuel cells operate at relatively low temperatures and are composed of two electrodes and a conductive elecrolyte.

Perfluorosulfonic Acid Membranes for Fuel Cell and Electrolyser Applications

Advances in the electrochemical conversion of water to and from hydrogen and oxygen have principally been achieved through the development of new materials and by understanding the mechanisms of the degradation of proton exchange membrane fuel cells (PEMFC) during operation.
