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.
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).

HYDRion™ Products are catalyzed membranes for water electrolysis applications based on NAFION®
membranes. In addition to manufacturing Catalyzed Coated Membranes for fuel cells, Ion Power produces catalyzed
membranes for water electrolysis. These materials are used for laboratory gas generators and hydrogen injection systems for
internal combustion engines.

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.

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
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.

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.

Ion Power distributes SGL Carbon's SIGRACET® graphite paper:
SGL Group is thus among the few companies worldwide to undertake mass production of key components for PEM fuel cells.
The quality of these graphite components is of eminent importance to the performance of the fuel cell.
Ion Power has found that the SIGRACET® grade gas diffusion media offers the best performance in all fuel cell applications and we have been providing this for years
to our customers.
Typical standard grades for general applications are GDL 24/25 AA, BA, BC; GDL 10 AA, BA, BC and
GDL 34/35 AA, BA, BC.
