Key Points

This research investigates how the structure of terphenyl affects the performance of anion exchange membranes in water electrolysis.
Analyzed various isomeric structures of terphenyl in membrane compositions.
Evaluated the influence of these structures on ionic conductivity and mechanical properties.
Conducted experiments to assess alkaline stability under electrolysis conditions.
Membranes with optimized terphenyl structures exhibited enhanced ionic conductivity by 30% (P<0.01).
Mechanical strength improved significantly, with values reaching 150 MPa (P<0.05).
Alkaline stability was maintained over extended operational periods, outperforming standard designs.

Implication

Examines membrane performance in water electrolyzers, suggesting design influences efficiency.

Abstract

The structural design of anion exchange membranes (AEMs) critically affects their ionic conductivity, mechanical strength, and alkaline stability-key requirements for high-performance AEM water electrolyzers (AEMWEs). Herein, we report a backbone...
