Thermally Stable Hydrocarbon-based Anion Exchange Membrane and Ionomers

RPI ID: 2020-073-602 / 2020-073-601 / 2020-073-201

Innovation Summary:
This suite of innovations introduces a class of hydrocarbon-based anion exchange membranes (AEMs) and ionomers that exhibit exceptional thermal and chemical stability. These materials are engineered with tailored polymer backbones and functional groups that maintain high ionic conductivity while resisting degradation under alkaline and high-temperature conditions. The membranes are suitable for use in electrochemical devices such as fuel cells and electrolyzers, where durability and performance are critical. The technology enables scalable production of AEMs with tunable properties for diverse energy and environmental applications.

Challenges / Opportunities:
Conventional AEMs often suffer from poor thermal and alkaline stability, limiting their long-term use in demanding electrochemical environments. This invention addresses these limitations by offering a hydrocarbon-based alternative to fluorinated membranes, reducing cost and environmental impact. The materials open new opportunities for next-generation clean energy systems, including zero-emission fuel cells and CO₂ electrolysis. The technology also supports the transition to sustainable energy by enabling more robust and efficient electrochemical platforms.

Key Benefits / Advantages:
✔ High thermal and alkaline stability for extended device lifetimes
✔ Hydrocarbon-based structure reduces cost and environmental footprint
✔ High ionic conductivity under operating conditions
