Description

The XION PENTION-AEM membranes are composites of poly(norbornene) based resin with reinforcements. Its Anion exchange capacity is at 3.4 to 3.6 mequiv/g. PENTION anion exchange membranes offer excellent mechanical strength and stability. Depending on thickness and degree of cross-linking these membranes demonstrated current densities up to 9 A/cm2 (or >3 W/cm2 power densities) in alkaline fuel cells (per recent papers published by NREL, University of South Carolina, and Georgia Institute of Technology).

Xergy produces Composite PENTION AEMs in 5, 10, 20, 30, and 50µm thicknesses. Membranes are available in 5x5cm, or 10x10cm, or 15x15cm sizes. This image shows the chemical structure of the PENTION ionomer. XION PENTION-AEMs are suitable for use in fuel cells, electrolyzers, electrodialysis, redox flow batteries, electrochemical compressors, and a wide variety of other applications. Composite PENTION AEMs are currently offered with 5% or 15% crosslinking levels.

XION Composite Pention Membranes are ultra-thin, ultra-strong, and provide ultra-high performance while demonstrating highly stable performance as reinforced anion exchange membranes (AEM). The ionomer structure contains a poly(norbornene) backbone with quaternary ammonium functional groups. A reinforcement layer is integrated into the structure of the membrane to provide enhanced mechanical properties. The enhanced mechanical properties as free-standing membranes, providing higher ionic conductance without sacrificing strength.

Benefits of Xion Composite Pention AEMs:

-High anionic conductivity

-Great chemical stability at low and high temperatures

-Ultra-thin membranes with excellent mechanical strength
