Abstract：

Anion exchange membrane (AEM) water electrolysis is an important direction for green hydrogen production, but the durability of AEM remains a major challenge. Due to the excellent thermal stability, chemical and mechanical stability of polyphenylene sulfide (PPS), this paper proposed to introduce the diphenyl sulfide monomer into AEM. Through a simple and controllable superacid-catalyzed polycondensation reaction, a polyarylpiperidine polymer without aryl ether bonds was successfully synthesized, and the corresponding piperidine-functionalized AEM was further prepared for water electrolysis to produce hydrogen. The performance test results showed that the ion conductivity of the membrane could reach 111.2 mS/cm at 80 ℃; after being immersed in 1 mol/L KOH solution at 80 ℃ for 1 080 hours, its OH conductivity could still retain 89.3% of the initial value, and no obvious changes in chemical structure were observed, demonstrating excellent alkali stability. In addition, when the membrane was assembled in a water electrolyzer and continuously operated at 60 ℃, 0.6 A/cm2 of current density and 1 mol/L KOH electrolyte for 1 385 hours, the voltage of the electrolyzer only increased by 0.15 V, showing outstanding stability. The above results fully confirm that this type of AEM has good practical application prospects in the field of alkaline water electrolysis.
