Anion exchange membrane (AEM) water electrolysis is a new hydrogen production technology that combines the high performance of proton exchange membrane (PEM) electrolysis and the low cost of alkaline (ALK) electrolysis. It is considered the most advanced green hydrogen production technology and will quickly meet the market demand. The hydrogen production system of AEM pure water electrolysis with many advantages is expected to further reduce the cost, becoming the mainstream technology route product in the future.
