Catalyzed Fuel Cell Membranes

Ion Power was the first company to commercialize a Catalyst Coated Membrane (CCM) made from cast film based on NAFION ® PFSA polymer. Our patented process results in a durable and very cost effective CCM for use in hydrogen or reformate fuel cell applications. Catalyzed coated fuel cell membrane

Ion Power's catalyzed coated membranes give you Higher power density with 20-30 micron membrane thickness. Longer membrane life from stable NAFION® ionomer. Enhanced sealing integrity and durability with lower costs. Our unique fabrication method results in a tougher perimeter area (outside the active region).

Nafion polymers and dispersion solutions

NAFION® Products

NAFION® is a registered trademark of E.I. DuPont de Nemours brand of perfluorosulfonic acid/TFE copolymer. NAFION® polymer has excellent chemical stability (similar to TEFLON®) while at the same time allowing ion transport.

These properties have led to interest in the use of NAFION® polymer for various electrochemical applications from industrial chloralkali cells to fuel cells.

Please click on our resources page for technical information related to NAFION® products or go to our company store for prices.

DuPont™ NAFION® products are available in various forms:

Pellets
Used for acid catalysis of many organic reactions. Product names include: NR40 (1000 EW polymer) and NR50 (1100 EW polymer). The product is also available in its precursor form as R1100 and R1000.

Non-Reinforced Films
These films are used as separators in electrochemical cells requiring high ionic conductivity, for example in fuel cells and water electrolyzers. Product names include:N115, N117 and N1110.

For pricing please go to our company store. More technical details are also available on our Resources page.

XL Membrane
DuPont™ Nafion® XL membrane is an extended-lifetime reinforced membrane based on chemically stabilized perfluorosulfonic acid/PTFE copolymer in the acid (H+) form.

The reinforcement improves the membrane's handling and physical properties.

When the reinforcement is combined with the chemically stabilized polymer, the membrane exhibits both substantially lower fluoride ion release and longer operating durability under fuel cell conditions.

Cast Films
DuPont™ NAFION® PFSA NR-211 and NR-212 membranes are non-reinforced dispersion-cast films, based on chemically stabilized perfluorosulfonic acid/PTFE copolymer in the acid (H+ ) form.

The physical properties remain the same for the stabilized membranes, which exhibit substantially lower fluoride ion release compared to the non-stabilized polymer - a sign of improved chemical durability.

NAFION® PFSA membranes are widely used for Proton Exchange Membrane (PEM) fuel cells and water electrolyzers. The membrane performs as a separator and solid electrolyte in a variety of electrochemical cells that require the membrane to selectively transport cations across the cell junction.

The polymer is chemically resistant and durable.

Fabric Reinforced Membranes
These reinforced films are typically used in industrial sized electrochemical applications with large areas (typically in square meters) where membrane strength is required. Product names includeN324 and N424.

Please click on our resources page for technical information related to these products.

Polymer Dispersions
The NAFION® polymer is dissolved in a dispersion which can be used for casting films or manufacturing other products containing NAFION® polymer. Available products include: D520, D521, D1020, D1021, D2020, and D2021. D dispersions are manufactured by DuPont™ and distributed by Ion Power on a global basis.
