Clean Technology

Orion products are not EPA PFAS, they reduce PGMs by 90%, cost by 30%, and membrane thickness by 50%.


The advantage of AEM over PEM



Orion delivers big on the long-sought-after, game-changing approach of using AEM, anion exchange membrane, in alkaline environment to accomplish production and storage of clean energy technologies. Orion AM was proven to be the most durable membrane of over 50 tested by NREL, withstanding 80°C KOH for 1000h with virtually no degradation.

Hydrogen electrolyzer

A 33% reduction in cost for AEM vs PEM has been calculated: 90% reduction in precious metal catalysts, 50% reduction in membrane thickness needed. The alkaline-based technology of hydroxide exchange rather than proton exchange negates the need for platinum catalysts and titanium housings, thus making AEM a decidedly more cost-effective approach to clean energy than PEM.


Whether developing fuel cells for zero-emission fuel cell vehicles, wind or solar energy delivery normalization, or hydrogen generation electrolyzers, AEM use offers strong cost advantages over PEM. Durable Orion AEM is the energy breakthrough needed for the future of clean energy.



Technical description of ORION CMX

Clean Energy Solutions for Devices at a Fraction of the Cost of PEM - Up to 90% Reduction in Catalyst

While cation exchange polymers and membranes have been available for over 30 years, there are limited sources for anion exchange polymers and membranes, slowing the development of new, transformational electrochemical technologies that can deliver clean energy solutions at reduced costs.

Orion Polymer introduced a new class of anion exchange polymers that can perform as a separator and as a solid electrolyte in a variety of electrochemical energy conversion technologies such as fuel cells, hydrogen electrolyzers, and flow batteries.

Orion CMX provides selective transport of anions (including OH–) across the membrane and electrodes in electrochemical cells, while offering excellent chemical stability in alkaline conditions and tough, durable mechanical properties – the breakthrough the field has been waiting for.

Orion Polymer will enable you to develop your technologies with high-performance, stable polymers.

Orion Polymer’s AEM, Anion Exchange Membrane, make clean energy of the future possible by enabling hydrogen generation and storage with reduced cost over PEM, with no corrosive acid environment, and vastly cheaper components for MEAs, cathodes and housings.

About ORION CMX Delivering Durability

ORION AMX, the previous generation of membrane before ORION CMX, was an aromatic polymer containing alkyltrimethylammonium cation groups which exhibits excellent chemical stability in alkaline conditions, tough mechanical properties, high ion conductivity, high ion exchange capacity, low water swelling, and good solubility in a variety of solvents including alcohol/water mixtures.

Please see the NREL study which compared 50+ anion exchange membranes, finding Orion AM the only durable membrane, exhibiting virtually NO degradation at 80°C over 1000h in KOH (PPN5 in the study).  Orion’s BN2 is the second most durable AEM of the NREL 50+ field studied.


Orion CMX Membrane has superceded Orion TM1, Durion, and AMX in performance and durability. It is available in sheets of 10cm x 10cm, 20cm x 20cm, and in rolls of membrane 24cm wide by 25 meters long, in single rolls or multiple rolls. Soon we will introduce 45cm wide rolls as well.

We cater to all custom projects and will make them stock items for you. Contact us!

Technical specs, Orion CMX, Orion TM1, Orion BN2, AMX

High conductivity (>60 mS/cm)

Highest conductivities vs. IEC of over 50 AEM analyzed (30-35mS/cm, ~2mmol cation/g)

The Most Durable anion exchange membrane at 80°C/1000h (AM) and the second most durable of 50+ tested (BN2)

Virtually no degradation after durability testing at 80°C/1000h: 

  • No conductivity loss (AM), Less than 0.5% conductivity loss (BN2) at 80°C
  • No IEC loss (BN2), less than 0.5% IEC loss (AM) at 80°C

Greater than 3x the Ion Exchange Capacity of Nafion! (OH- vs H+)

Withstands high pressure differentials

Maintains the same physical appearance after 1000h in KOH at 80°C

Best backbone, best cation and best R groups to provide enhanced chemical durability for the future of AEM development.

ORION CMX is the only commercial membrane to be able to withstand repeated cycling to zero and back, and high pressure differentials.

Orion-type AEM membranes are durable and “show the most promising results in conductivity and IEC”  Meek, 2019.


ORION CMX Membrnae is a Self-Supporting membrane, ~40um thick, 10cm x 10cm, or 20cm x 20cm, or supplied as single or multiple rolls of 24cm x 25 meters (or custom length).

AEM does not need the thickness of PEM. Our same Orion CMX can be used for HT-PEM with a simple treatment.
