Versogen AEMs

Versogen is the global leader in superior polymer design and engineering. Their anion exchange membranes (AEM) deliver on the long-awaited promise of unprecedented durability, performance, and scalability. These versatile membranes can be used in multiple cross-sector applications.

When performance and durability matter, Versogen delivers.

The patented PiperION platform technology is transforming the energy industry with robust and affordable membranes that perform efficiently in alkaline environments. Versogen membranes also enable the use of low-cost construction materials in electrolyzers, fuel cells, and other electrochemical devices to surpass incumbent technologies, including proton exchange membranes (PEM).

PiperION hydrocarbon membranes are manufactured from poly(aryl piperidinium) resin and this class of polymers introduce an alkaline stable cation, piperidinium, into a rigid aromatic polymer backbone that is free of ether bonds. Anion exchange membranes (AEM), or hydroxide exchange membranes (HEM), formed from PiperION polymers exhibit superior chemical stability, anion conductivity, decreased water uptake, good solubility in selected solvents, and improved mechanical properties.

Self-supporting AEMs, mechanically reinforced AEMs, and dispersion products are currently offered through Fuel Cell Store.

Versogen checks all the boxes.

Scientific Literature for Various Use of Versogen Membranes and Dispersion Products:

The article by Wang et al. entitled "Poly(aryl piperidinium) membranes and ionomers for hydroxide exchange membrane fuel cells" is considered to be an excellent source that describes the polymer chemistry and fuel cell operation of PiperION membranes with hydrogen and CO2-free air reactants at a temperature of 95 °C.  This article also investigates the ionic conductivity, chemical stability, mechanical robustness, gas separation, and selective solubility aspects of poly(aryl piperidinium) based AEMs.

The article by Wang et al. entitled "High-Performance Hydroxide Exchange Membrane Fuel Cells THrough Optimization of Relative Humidity, Backpressure, and Catalyst Selection" is considered to be an excellent source that describes the polymer chemistry and fuel cell operation of PiperION membranes under different operational parameters in order to eliminate the anode flooding and cathode drying out issues in order to achieve a blanced water management.  With further optimization on the catalyst, a peak power density of 1.89 W/cm2 in H2/O2 and 1.31 W/cm2 in H2/Air have been achieved.  

The article by Luo et al. entitled "Structure-Transport Relationships of Poly(aryl piperidinium) Anion-Exchange Membranes: Effect of Anions and Hydration" is considered to be an excellent source that describes the transfer of different anions across AEMs that are manufactured from poly(aryl piperidinium) resin.  Nanostructure, hydration or water uptake as a function of the counter anion, phase-separation in regars of its polymer morphology, anion conductivity as a function of water content (vapor or liquid) and anion radius are some of the other aspects that have been discussed in this publication.

The article by Zhao et al. entitled "An Efficient Direct Ammonia Fuel Cell for Affordable Carbon-Neutral Transportation" is considered to be an excellent source that describes economics of hydrogen, methanol, and ammonia as fuel for transportation applications, performance of poly(aryl piperidinium) based AEMs for direct ammonia fuel cell at 80 °C. 

The article by Archrai et al. entitled "A Direct Ammonia Fuel Cell with a KOH-Free Anode Feed Generating 180 mW cm-2 at 120 °C" investigates the electrochemical performance of poly(aryl piperidinium) based AEMs for direct ammonia fuel cell at 120 °C. 

The article by Endrodi et al. entitled "High carbonate ion conductance of a robust PiperION membrane allows industrial current density and conversion in a zero-gap carbon dioxide electrolyzer cell" investigates the electrochemical performance of poly(aryl piperidinium) based AEMs for electrochemical reduction of CO2 or carbon dioxide electrolyzer applications. This study demonstrated that partial current densities of greater than 1 A/cm2 can be achieved while maintaining high conversion (25-40%), selectivity (up to 90%), and low cell voltage (2.6-3.4 V).

Please note that a current lead time of 2 - 4 weeks is to be expected.
