Design and operating principles for high-performing anion exchange membrane water electrolyzers

Andrew W. Tricker et al.

Summary: Anion-exchange-membrane water electrolyzers (AEMWEs) have the potential to produce clean hydrogen using low-carbon renewable electricity efficiently and at a lower cost compared to existing technologies. This study overcomes the challenges faced by AEMWEs by integrating a reference electrode in the membrane-electrode assembly, which helps identify the dominant factors affecting the polarization behavior of the anode and cathode. By adjusting the electrode properties and operating strategies, such as using a more hydrophobic and optimal loaded cathode, a high porosity anode, and operating with a dry cathode, a high-performing and durable PGM-free AEMWE was achieved with negligible degradation over 500 hours.

Increasing the Electrolyte Salinity to Improve the Performance of Anion Exchange Membrane Water Electrolyzers

Ruggero Rossi et al.

Summary: Direct operation of anion exchange membrane water electrolyzers with near-neutral pH feeds faces challenges in performance and stability. However, the addition of low concentrations of alkali metal salts improved performance and stability. Increasing the salinity of near-neutral pH solutions represents a cost-effective strategy to improve the performance of AEMWE compared to ultrapure electrolytes.

KOH vs Deionized Water Operation in Anion Exchange Membrane Electrolyzers

Noor Ul Hassan et al.

Summary: Anion exchange membrane water electrolyzers (AEMELs) have potential advantages over proton exchange membrane electrolyzers (PEMELs), but the methodology for switching between salt solution and deionized water and the impact of residual salt on cell performance are unclear. This paper studies the transition from salt to deionized water in AEMELs and suggests that a large volume of deionized water is required to achieve optimal performance during the transition.

Self-Adhesive Ionomers for Alkaline Electrolysis: Optimized Hydrogen Evolution Electrode

Hui Min Tee et al.

Summary: Hydrogen produced through low-temperature water electrolysis using anion exchange membranes combines the benefits of liquid-electrolyte alkaline electrolysis and solid-polymer proton exchange membrane electrolysis. The study found that using cathode ionomers with high ion exchange capacity improved cathode durability, and using ionomers soluble in the spray-coated cathode ink further improved durability and reduced voltage.

Ionomer Optimization for Water Uptake and Swelling in Anion Exchange Membrane Electrolyzer: Hydrogen Evolution Electrode

Garrett Huang et al.

Summary: Green hydrogen produced through anion exchange membrane water electrolysis is a promising, low-cost chemical storage solution that requires a balance between ionic conductivity, water uptake, and ionomer swelling in the ACI to improve the performance of AEM-based devices. Higher IEC ACIs with light crosslinking are preferred in the HER electrode to fine-tune water uptake and ionomer swelling for optimal cell performance and reduced operating voltages.
