As of 10/13/2020, Fuel Cell Store sold out the entire stock for this product and we do not have any resin material left.  It is estimated that the next batch of the resin would be produced in early 2021.  Please bookmark this page and check for the updates time to time from the Fuel Cell Store team.

This medium molecular weight resin is the industry-leading anion exchange ionomer.  It has long lifetime durability (>1000 hours) and high temperature stability (up to 80 ºC) with an ion exchange capacity of >2.00 mequiv./gram (in OH- form).  Medium molecular weight anion exchange resins inherently have better mechanical and chemical stability compared to low molecular weight anion exchange resins, hence more suitable for making a dispersion for fabricating self supported membranes.  This material can also be used to prepare catalyst inks, post-coating the catalyzed electrodes, or manufacture mechanically reinforced anion exchange membranes. 

Anion exchange membranes (AEMs) manufactured from Orion TM1 DurionTM resin demonstrated excellent durability and lifetime.  NREL's blind study that was conducted in October 2019 showed that AEMs based on Orion's TM1 DurionTM resin can be operated at temperatures of up to 80 ºC with 1M KOH for more than 1000 hours.  Virtually, there was no degradation.  Such excellent durability and high temperature stability makes Orion TM1 DurionTM resin an ideal polymer material to manufacture anion exchange membranes with various thicknesses either in the mechanically reinforced or self-supporting forms.  Additionally, Orion TM1 DurionTM medium molecular weight resin can also be used to manufacture anion exchange dispersions for preparing catalyst inks or casting membranes.  Simple solvents can be used to dissolve this resin material and obtain a dispersion solution with various weight percentages.  Having the capability of obtaining an anion exchange dispersion solution with similar solvents that are currently used in the fuel cell industry also eliminates the needs for changing the currently existing alkaline electrode manufacturing processes (compared to processes that utilize catalyst inks with dispersions that use NMP, DMSO, etc. type difficult to remove organic solvents).  Dissolution instructions will only be sent to the purchaser after the purchase of the product (as a hard copy in the same shipment package) in order to protect IP rights of the supplier.

AEMs or dispersions made with Orion TM1 DurionTM resin can potentially be used for the following applications: alkaline fuel cells (with or without electrolyte), alkaline electrolyzers, alkaline batteries, electrochemical compressors, and a wide variety of other electrochemical devices.  AEMs or dispersions based on Orion TM1 DurionTM resin are stable under neutral and alkaline conditions.

Lead time is approximately 8 - 12 weeks to ship.
