Clean Energy Through Orion TM1 Anion Exchange Membrane

Durable-Orion-AEM

Orion delivers 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 TM1 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.

AEM

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 TM1

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.

OrionTM1 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 TM1 Delivering Durability

OrionTM1 is 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 TM1 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.

Products

Orion TM1 is available as ionomer powder / resin, as an alcohol/water ionomer solution, as 5µm thick reinforced membrane, and 25µm thick reinforced membrane forms. Orion TM1 is available as free standing membrane or composite membrane by custom order. 

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

Technical specs, Orion TM1 and Orion BN2, Next Gen

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 (TM1) and the second most durable of 50+ tested (BN2)

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