520	3		_aWe report polysulfone-based anion-exchange membranes cross-linked using three distinct cross-linkers (i.e., 4,4′- trimethylenebis(1-methyl-piperidine) (BMP), N,N,N′,N′-tetramethyl-1,6-diaminohexane (TMHDA), and 1,4-dia zabicyclo[2.2.2]octane (DABCO)), designed for water electrolysis application. The cross-linked chloromethy lated polysulfone membranes exhibit quaternization functionality, which can facilitate hydroxide-ion transport. Additionally, the cross-linked polysulfone membranes exhibit high thermal and mechanical stability. Among the cross-linked polysulfone membranes, the BMP-induced cross-linked polysulfone membrane displays an ionexchange capacity of 1.58 mmol/g and an ion conductivity of 53.7 mS/cm at 80 ◦C, along with a water up take of 50 percent and a swelling ratio of 23 percent, demonstrating good electrochemical properties and high dimensional stability. Moreover, the BMP-induced cross-linked polysulfone membrane exhibits a higher anion-exchange membrane water electrolysis performance and lower impedance than the other cross-linker-induced crosslinked polysulfone membranes. More importantly, it exhibits better water electrolysis cell performance than commercial FAA-3-50 membranes.
