Novel components in anion exchange membrane water electrolyzers (AEMWE’s): Status, challenges and future needs. A mini review

Abstract

AEMWE is a novel technology combining the advantages of the already recognized electrolyzer technologies, i.e. Proton Exchange Membrane WE (PEMWE) and Alkaline WE (AWE) with the promise to eliminate the disadvantages of both. This review presents an overall opinion of the current state of AEMWE technology, focusing on component’s performance, durability and overall operation while identifying the critical gaps in the technology. It presents our perspective on the requisite developments in AEMWE at the cell component level in order to become a viable technology amongst other electrolyzer technologies with the potential for widespread adoption and commercialization.
