Breakthrough in Flexible Tubing Materials for Fuel Cells and Electrolyzers

In the ever-evolving landscape of alternative energy, Venair Group has emerged as a trailblazer with its groundbreaking material designed specifically for flexible tubing used in PEM (Proton Exchange Membrane) fuel cells and PEM electrolyzers. Developed in collaboration with two of the top OEMs (Original Equipment Manufacturers) in the North American fuel cell sector, this innovative material addresses the limitations of the commonly used FKM (Fluoroelastomer) while surpassing industry standards.

Challenges with FKM in PEM Systems

Traditional PEM systems have relied on FKM for critical components such as hydrogen and air conduits. However, this material presents a series of challenges that hinder scalability:

  • High Cost: FKM is notorious for its exorbitant cost, making it economically unviable for widespread adoption.
  • Supply Chain Instability: The FKM supply chain is prone to disruptions, leading to global shortages and hindering consistent production.
  • PFA Content: FKM contains PFAs (Per- and Polyfluoroalkyl Substances), which face prohibition in Europe in 2024 and in North America over the next two years.


Venair Group's Solution

In response to these challenges, Venair Group dedicated over five years to developing a superior material that has finally come to fruition. This revolutionary material not only addresses FKM's shortcomings but enhances crucial properties valued in the PEM fuel cell and PEM electrolyzer industry:

Reduced Permeability: Venair's material reduces tube permeability by over 40% compared to FKM constructions, ensuring enhanced performance and efficiency.




  • Quantitative Purity: The material exhibits significantly lower leachables, contributing to a cleaner and more efficient operation.
  • Qualitative Purity: Venair's material releases contaminants that are far less harmful to the PEM membrane and catalyst compared to FKM, a result of extensive analysis and research on membrane degradation.
  • Lower Electrical Conductivity: Both the material and the imparted conductivity to the contacting medium showcase lower electrical conductivity, customizable based on specific demands.
  • Cost-Efficiency: Venair's material comes at a significantly lower price point than FKM, making it a cost-effective choice for manufacturers and end-users alike.
  • Free of PFA substances: specifically formulated so that it can replace FKM tubing without any worldwide regulatory problems




  • Supply Chain Assurance: Venair Group ensures a stable and independent supply chain, guaranteeing uninterrupted production.

The product has been certified with the highest rating by UL-94 (Safety of Flammability of Plastic Materials) certification. The best rating is V0 which meets all the requirements of the most important industries that use Fuel Cells: automotive, aerospace, marine...
