Researchers enhance durability of pure water-fed anion exchange membrane electrolysis
Anion exchange membrane (AEM) water electrolysis is widely recognized as a key technology for next-generation green hydrogen production. Currently, most AEM systems rely on alkaline supporting electrolytes such as potassium hydroxide, which can cause issues including bipolar plate corrosion, shunt current, and accelerated membrane degradation.
Achieving stable operation with pure water feed is the goal for AEM water electrolysis. However, obstacles remain such as the instability of the membrane-electrode three-phase interface, limited current density, and poor durability.
