Product Description

Ionomr designs and manufactures breakthrough advanced ion-exchange materials to enable rapid growth of the hydrogen economy. Ionomr’s advanced proton exchange membranes and polymers are a breakthrough in material science with a uniquely stable hydrocarbon structure, making it the only product of its kind.

Pemion® represents a fundamental shift in the approach to proton exchange technology through its migration from perfluorosulfonic acid (PFSA) chemistry to hydrocarbon materials, providing substantially lower gas crossover and addressing PFAS-related environmental and end-of-life issues at considerably higher performance. Pemion® enables major efficiency and performance gains, while aligning with needs of the renewable economy. It is the only environmentally friendly option on the market.

Produced on reinforcement at thicknesses competitive to leading PFSA membranes in the industry, Pemion® provides leading conductance and durability without compromise. For use in fuel cell applications including heavy duty transport & automotive, hydrocarbon based Pemion® membrane and ionomer offers several advantages over incumbent perfluorinated materials to increase the efficiency, versatility, and lifetime of fuel cell engines, including: lower gas crossover for increases to range and the lifetimes of both membrane and catalyst; higher proton conductivity for additional gains to efficiency and power density; significantly greater temperature stability to enable many system design benefits; & a substantially easier end-of-life precious metal recovery, reducing costs & eliminating the environmental concerns
specific to acidic perfluorinated compounds.

Technical Specifications

General Properties
Specific Gravity
Specific Gravity
Specific gravity (SG) is the ratio of the density of a substance to the density of a reference substance; equivalently, it is the ratio of the mass of a substance to the mass of a reference substance for the same given volume.

For liquids, the reference substance is almost always water (1), while for gases, it is air (1.18) at room temperature. Specific gravity is unitless.
Total Thickness
Total Thickness
Total thickness is taking into account all the films, coatings, adhesives, release liners and special layers and is the maximum thickness of a film or tape.
15 μm
Chemical Properties
Water Absorption 95 - 140 %
Mechanical Properties
Elongation is the process of lengthening something.

It is a percentage that measures the initial, unstressed, length compared to the length of the material right before it breaks.

It is commonly referred to as Ultimate Elongation or Tensile Elongation at break.
30 %
Tensile Strength
Tensile Strength
The tensile strength of a material is the maximum amount of tensile stress that it can withstand while being stretched or pulled before failure.

Some materials break very sharply, without plastic deformation, in what is called a brittle failure. Others, which are more ductile, including most metals, experience some plastic deformation and possibly necking before fracture.
Tensile Strength
Tensile Strength
Tensile strength determines the resistance of a material to break under tension and it measures how much elongating load (or tensile stress) it can handle before fracture.

To make it simple, it measures how much force we have to apply when pulling apart a material before it breaks.
40 MPa
Thermal Properties
Glass Transition Temperature (Tg)
Glass Transition Temperature (Tg)
The glass transition temperature for organic adhesives is a temperature region where the polymers change from glassy and brittle to soft and rubbery. Increasing the temperature further continues the softening process as the viscosity drops too. Temperatures between the glass transition temperature and below the decomposition point of the adhesive are the best region for bonding.

The glass-transition temperature Tg of a material characterizes the range of temperatures over which this glass transition occurs.
300 °C

Additional Information

Non Disclosure Agreement

This is a proprietary product from Ionomr, therefore, we require a signed NDA between the end customer and Ionomr before we are able to ship out the material, either for commercial use, or research.

This is done to prevent reverse engineering and public disclosure. The NDA does not restrict patenting anything, but does include the physical materials and their composition as confidential which prevents specific disclosure in a patent or otherwise but not calling out use of an AEM including Aemion by trade name. The test results are included as confidential information, and require  approval from both parties to disclose. We are not concerned about blocking any publications, but would typically advise if we believe better results can be achieved.

We have a more explicit MTA (Materials Transfer Agreement) we use with academic/research organizations which outlines more detail around materials IP and publication.

Please find the NDA here and fill it in when contacting us for quotations.
