Role of water structure in alkaline water electrolysis [PDF]

iScience, 2022
Summary: Herein, with the help of experimental and first-principles density functional theory (DFT)-based studies, we have shown that structural changes in the water coordination in electrolytes having high alkalinity can be a possible reason for the ...

Separators and Membranes for Advanced Alkaline Water Electrolysis. [PDF]

Chem Rev
Traditionally, alkaline water electrolysis (AWE) uses diaphragms to separate anode and cathode and is operated with 5-7 M KOH feed solutions. The ban of asbestos diaphragms led to the development of polymeric diaphragms, which are now the state of the art material. A promising alternative is the ion solvating membrane.
