Designing Electrocatalysts for High-Efficiency Anion Exchange Membrane Water Electrolysis The efficient production of hydrogen through the electrolysis of water has long been a sought-after challenge. A promising solution is found in anion exchange membrane electrolysis, which do not require expensive platinum group metals (PGMs) as electrocatalysts. However, electrocatalysts based on non-PGMs exhibit low catalytic activity, thus presenting a hurdle for achieving high-efficiency anion exchange membrane water electrolysis. In this study, we present a roadmap for developments of electrocatalysts aimed at improving water electrolysis efficiency. By systematically analyzing both the extrinsic and intrinsic effects of the electrocatalysts, we have derived a more efficient direction for development of electrocatalysts. The research was a collaborative effort involving the Korea Institute of Materials Science (KIMS), the Korea Advanced Institute of Science and Technology (KAIST), and Chungbuk National University (CBNU).
