General description

Nafion NRE-212 membranes may be used in the investigation of oxygen reduction reaction (ORR) activity of Pt/C catalyst.

Application

Carbon nanotube reinforced Nafion composites may be prepared to be used in H2O2 fuel cells.
Nafion perfluorinated membrane is mainly used as a proton exchange membrane (PEM) for fuel cell applications. It has good proton conductivity and good physio-chemical stability. It can also be used as a reference membrane to compare and prepare high-performance composite membranes.
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.

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.
