Ion Power Inc.'s Value Added Products Containing Nafion™

Utilizing our combined industrial experience of many years working with Nafion™, we are constantly innovating new products and applications with Nafion™ together with our customers.

Our key products are LIQUion™, LITHion™, POWDion™, VANADion™, HYDRion™, and Catalyst Coated Membranes (CCM).

Product descriptions are listed below.

LIQUion™ Dispersions

LIQUion™ dispersions contain Nafion™ that is dispersed in a water or alcohol solvent mixture. They are used in various applications, including coatings, films, and catalyst layers, where they provide unique properties, such as high proton conductivity, good chemical and thermal stability, and small particle size.

The LIQUion™ dispersion has particle sizes measured down to a few hundred nanometers in size, indicating a dispersion down to the molecular level.

LITHion™ Dispersions

LITHion™ is a neutral dispersion that contains lithiated Nafion™ polymer in an Isopropyl Alcohol solvent. It is widely used in research advanced lithium-ion batteries and other electrochemical devices. This pre-dispersed slurry can be easily applied to substrates, mixed with other solutions, or used to cast films and coat other materials.

Nafion™ Tubing

Ion Power has developed a unique manufacturing process for the conversion of flat sheets of the NAFIONTM membranes into a tube with a heat-sealed seam. Tubes can be used in electrochemical processes where cell construction is in a cylindrical format.

The following grades of NAFIONTM membranes are available for tube forming, N324, N424 and N438. The seams can be formed in an “Overlap” configuration or a “Pinch” configuration, see photos. Seam lengths up to 1.23 meters are available, and tube diameters from 1 cm to 122 cm are available. The seam width is fixed at 2 cm; however small diameter tubes with “wrap-around” pinch seams have 2 mm seam widths.

Overlap seams are inherently stronger than the base membrane material, and in tension the base material will fail prior to the seam failure. Whereas Pinch seam configurations the seam will fail on tension forces greater than 10 pounds per linear inch of seam. Failure will result in re-inforcing fabric being pulled away from the ionomer layer of the membrane resulting in a hole in the membrane at the leading edge of the seam.

An option for forming a bag is also available by applying a pinch seam at the end of the tube. Ion transport properties at the seam are severely diminished and should be considered zero for engineering design purposes.


POWDion™ is a powder made from the Nafion™ perfluorosulfonic acid polymer.

This product comes in soluble and insoluble forms, with different particle sizes ranging from -40+60-mesh to -200-mesh.

The VANADion™ Membrane is a composite membrane containing a thin Nafion™ coating on one face of a porous supporting membrane. It's used in electrochemical energy storage batteries and various other electrochemical applications. This membrane is supplied in a dry form but should be properly wetted out prior to use.

The rugged support of the membrane allows for easy and fault-free cell assembly, while its high conductivity enables high cell power output while maintaining good cell voltage. With a positive side orientation, the membrane should be noted during cell assembly and start-up.

Manufacturers can enhance the performance of their electrochemical devices by incorporating VANADion™ Membrane, which offers superior proton conductivity in a rugged supported membrane structure.

The HYDRion™ Electrolysis Membrane is a high-performance ion exchange membrane used in water electrolysis systems for hydrogen production. This product has a high proton conductivity and low hydrogen crossover, which makes it ideal for use in PEM water electrolyzers.

By using HYDRion™, manufacturers can achieve efficient and reliable hydrogen production, making it an essential component of modern energy storage and conversion technologies.

Fuel Cell Grade Catalyst Coated Membranes (CCM) & Kapton Framed

Ultra-thin (<20 micron) NAFION® containing membranes offer high power density and low resistance structures for MEA applications.

Membrane where you need it; not where you don’t! The catalyst Layer and membrane layer are formed in place on the GDL so no high cost membrane is needed. The KAPTON™ frames are integrated into the MEA parts resulting in a 1 mil (25.4 micron) thick KAPTON™ border.

Ion Power’s MEA manufacturing line utilizes state-of-the-art continuous roll to roll coating operations that are set up to handle the prototype and high-volume production requirements of today’s growing PEM fuel cell industry. So whether you need one or thousands of catalyst coated membranes for hydrogen fuel cells or water electrolyzers, contact Ion Power to discover how your application can “Turn On With Ion Power Catalyzed Membranes.”
