Summary The development of alkaline membranes with high conductivity and stability is a significant challenge for the commercial application of advanced alkaline water electrolysis. In this study, a novel anion exchange membrane (AEM) was fabricated by quaternary ammonium poly (n‐methyl‐piperidine‐co‐p‐terphenyl) (QAPPT) and Ni‐Fe layered double hydroxide (LDH) synthesis for advanced alkaline water electrolysis. The uniform dispersion of Ni‐Fe LDH in the QAPPT/Ni‐Fe LDH composite membrane was confirmed by scanning electron microscopy, showing that Ni‐Fe LDH provides the composite membrane with high OH− conductivity and tensile strength. Among different membrane samples, the QAPPT/3% Ni‐Fe LDH composite membrane exhibited the best conductivity with 217.6 mS cm−1 at 80°C. Furthermore, the QAPPT/3% Ni‐Fe LDH composite membrane showed outstanding electrolysis performance of 1 A cm−2 at the voltage of 1.824 V at 60°C. According to a long‐term stability test, conducted at 500 mA cm−2 for more than 87 h, the QAPPT/3% Ni‐Fe LDH composite membrane achieved satisfactory electrolysis voltage. This study's results show that QAPPT/Ni‐Fe LDH composite membranes have excellent application prospects in advanced alkaline water electrolysis.

“…Furthermore, the research on many other functional polymers to fabricate AEMs with superior performances has been reported in some very recent articles. [159][160][161][162][163] In addition to the judicious choice of cationic groups and polymer backbones, conferring steric hindrance shielding on cationic groups and linkers is also an effective approach to regulating the AEM. Based on this, Zhang et al proposed to incorporate an alkyl extender to strengthen the chemical stability and improve the hydroxide conductivity of AEMs.…”

A low-cost anion exchange membrane water electrolysis (AEMWE) stack with good performance and durability is demonstrated in this study. The configuration of an AEMWE single cell, composed of an etched copper−cobalt oxide anode (eCCO) by a simple chemical etching and a polycarbazole-based anion exchange membrane (QPC-TMA) was optimized through various single-cell studies. The largesized three-cell AEMWE stack (total active area of 190.9 cm 2 ) with eCCO and QPC-TMA demonstrated durability with a degradation rate of 8.5 mV kh −1 as well as an energy conversion efficiency of 75% for 2000 h in 0.1 M KOH at 45 °C. Moreover, the production rate of H 2 is reported 40.4 L h −1 , thereby being equivalent to electricity produced by H 2 of 44 kWh kg −1 . To the best of our knowledge, this AEMWE stack has the highest performance and durability among the reported AEMWE stacks using non-platinum-group metal anodes and noncommercial membranes.
