Used in large fuel cell applications, including heavy-duty transportation, automotive and stationary power, Pemion™ offers superior chemical and mechanical stability, conductivity, durability and efficiency, all of which serve to dramatically reduce fuel cell unit costs.

Pemion™ is more environmentally friendly than traditional fluorinated membrane and polymer technology, reduces dependency on these increasingly regulated materials, and allows for simplified and less expensive recycling for the recovery of expensive end-of-life catalysts.

Bill HablinIonomr Chief Executive Officer, says: “Governments and regulators around the world Europe, in the US, indeed worldwide, are rightly demanding the elimination of toxic perfluorinated materials. Pemion™ is an ideal replacement for traditional materials due to its environmental benefits and superior performance. With our Pemion™ materials now in large-scale production, our partners can bring their fuel cell and other clean energy technologies to market faster, cleaner, and with better performance. Pemion™ offers a tangible differentiation in the heavy-duty market.”

DR Matthew BreitwieserChief Technology Officer of ionysis GmbH, said: “We have been working with Ionomr for several years, and after working with their Pemion® Materials have now achieved a leap in the performance of all-hydrocarbon membrane electrode assemblies (MEAs) competing with PFSA solutions. Based on this success, we founded our new company Ionysis to develop high performance hydrocarbon MEAs as a viable alternative to traditional solutions.”

Pemion™ represents a fundamental shift in proton exchange technology

Conventional polymers and membranes are made using perfluorinated sulfonic acid (PFSA) chemistry. Perfluorinated compounds are known environmental toxins that enter the aquatic environment, bioaccumulate in living organisms, and are difficult to recycle.

The elimination of these common substances from all sources is an urgent goal worldwide. Manufactured from environmentally friendly hydrocarbon materials, Pemion™ products avoid the environmental issues associated with traditional counterparts while still achieving maximum durability and performance.

In addition, the performance gains of Pemion™ materials and the reduction in gas crossover result in a significant reduction in the lifetime cost of hydrogen fuel cells. Higher temperatures are possible for higher power stacks with improved cooling and higher efficiency, and fuel cell lifetime is extended due to reduced degradation. Pemion has one of the highest room temperature conductivities available while maintaining its mechanical stability for improved overall efficiency and longer system life.

About Ionomr Innovations Ionomr Innovations revolutionizes electrochemistry with newly developed ion exchange membranes and polymers for clean energy. Ionomr’s Pemion™ and Aemion™ technologies provide cost, performance and sustainability benefits for fuel cells, hydrogen production and carbon capture, utilization and conversion. Founded in 2018, Ionomr employs 43 people in Vancouver, Canada and Rochester, New York.


Ionomr Innovations’ hydrocarbon-based Pemion™ membrane and polymer offer several advantages over established perfluorinated materials to increase the efficiency, versatility and durability of fuel cell engines in heavy-duty trucking and the automotive industry.

  • Benefits include: i) reduced gas crossover to increase the area and life of both the membrane and the catalyst; ii) higher proton conductivity for additional efficiency gains and power density; iii) much greater temperature stability to enable multiple system design advantages; and iv) much easier end-of-life precious metal recovery, reducing costs and eliminating the significant environmental concerns specific to acidic perfluorinated compounds.
  • The reduced solubility of gases in the polymer results in reduced transfer of hydrogen and nitrogen, resulting in an immediate reduction in parasitic losses and greatly reducing the formation of highly reactive radicals to minimize chemical degradation for the longest possible lifetime.
  • Unlike PFSA materials, hydrocarbon Pemion™ polymers are chemically stable up to 200°C, enabling a development platform for other fuel cell components to meet industry operating targets of 120°C.
  • Pemion™ membranes are manufactured on reinforcement in thicknesses competitive with industry leading PFSA membranes, with record conductivity enabling the highest performing systems. As a result, Pemion™ offers leading conductivity and durability without compromise.

About Aemion+™

The commercial launch of Pemion™ follows Ionomr’s earlier launch of its Aemion+™ membrane technology for industrial-scale production of green hydrogen through water electrolysis. Aemion+™ alkaline membranes are ultra-stable anion exchange membranes (AEMs) designed to eliminate traditional expensive water electrolysis components – such as iridium, platinum and titanium – and replace them with less expensive materials while maximizing performance. Ionomr is now conducting joint development activities for AEM electrolysis with industry giants Shell & Nouryon and has signed six additional MoUs with device manufacturers to accelerate commercial device adoption.

Durability test results for Ionomr’s Aemion+™ alkaline membranes, released earlier this year, achieved milestones that exceed internationally established target standards set for 2024.
