Innovation Summary:
This invention presents a class of anion exchange membranes (AEMs) made from functionalized styrene block copolymers. These polymers are engineered to possess high ion conductivity, thermal stability, and chemical resistance. A specific polymer formulation enables improved phase separation, creating defined ion channels for enhanced transport. The membranes support efficient hydroxide ion transfer, making them highly suitable for alkaline fuel cells and water electrolyzers. The design offers tunable mechanical and electrochemical properties through modification of the polymer backbone and functional groups. This family of materials is compatible with scalable membrane fabrication techniques and delivers robust performance across a wide pH range.
Challenges / Opportunities:
Alkaline electrochemical devices require membranes that combine high conductivity with chemical resilience. Existing AEMs often degrade under high pH conditions or suffer from poor mechanical strength. This invention addresses these issues through polymer design and tailored side-chain functionality. It creates opportunities for long-lasting AEMs in next-generation green energy systems. The technology offers cost-effective solutions for transitioning from fossil-based hydrogen production to water electrolysis.
