CyclAFlor^® Applications

Fuel Cell Ionomers

Fuel cells generate electricity and heat using an electrochemical reaction, not combustion, emitting only water if hydrogen is used as the fuel source. They are a critical component of the “hydrogen economy” – a vision of hydrogen as a clean energy source for distributed power generation, renewable (e.g., solar, wind) energy storage, and to replace natural gas for heating and gasoline for vehicle transportation. CyclAFlor^® advanced fluorinated ionomers are designed for next-generation fuel cells, helping to increase their efficiency, reduce reliance on rare catalysts, and advance clean energy goals across industries.

Built for Performance at the Molecular Level

Membrane Electrode Assemblies (“MEAs”) are the functional core of fuel cells, comprising a membrane, catalyst layers (anode and cathode), and diffusion media. The membrane component of a MEA can let either protons pass through from anode to cathode, but not electrons (a “Proton Exchange Membrane” or “PEM”) or vice-versa (an “Anion Exchange Membrane” or “AEM”). CyclAFlor catalyst binder ionomers improve MEA gas permeability, facilitating better oxygen and hydrogen diffusion at the catalyst interface and enabling potential reductions in platinum group metal usage. These benefits translate to longer lifespan, lower system cost, and improved overall fuel cell performance.

Materials Engineered for Harsh Conditions

With high chemical resistance and mechanical strength, CyclAFlor ionomers are ideal for harsh electrochemical environments.

Versatile Applications in Clean Energy Systems

In addition to fuel cell stacks, CyclAFlor Separator gas separation membranes play a role in clean hydrogen production – purifying gray and blue hydrogen made from methane or ammonia as a fuel source. CyclAFlor materials enable more efficient gas separation and contribute to the clean energy ecosystem.
