Versogen is the global leader in superior polymer design and engineering. PiperION anion exchange dispersion (also called PiperION ionomer) delivers on the long-awaited promise of unprecedented durability, performance, and scalability when it is used with their PiperION membranes (self-supporting or mechanically reinforced). This versatile dispersion can be used in multiple cross-sector applications for the preparation of anode and cathode inks or slurries, preparation of your custom thickness anion exchange memrbranes, etc. in order to achieve unparalled electrochemical performances for alkaline fuel cells, alkaline electrolyzers, and all other relevant electrochemical technologies.
PiperION dispersion (or PiperION ionomer) is manufactured from the functionalized PiperION resin material. The patented PiperION platform technology is transforming the energy industry with robust and affordable dispersion and membranes that perform efficiently in alkaline environments. Versogen dispersion and membrane products 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 dispersion product is 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 dispersion formed from PiperION polymers exhibit superior chemical stability, anion conductivity, decreased water uptake, good solubility in selected solvents, and improved mechanical properties. Products that are manufactured from the PiperION dispersion or catalyst layers that utilizes PiperION ionomer will provide superb electrochemical performance, which is ideal for your project and research needs.
Anion exchange dispersion, self-supporting AEMs, and mechanically reinforced AEMs products are currently offered through Fuel Cell Store.
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.
