Paragraph starter
The development of advanced anion exchange membranes (AEMs) is critical for the economic viability of water electrolysis as a method for storing renewable energy. Research indicates that AEMs enable the use of less expensive catalysts while offering operational advantages comparable to proton exchange membrane (PEM) systems. Key technical requirements for these membranes include high hydroxide conductivity, excellent chemical and mechanical stability, and gas tightness. A review of commercial AEMs highlights their varying performance, underscoring the need for continued material innovation to meet the demands of large-scale green hydrogen production.
