Abstract

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 large-sized three-cell AEMWE stack (total active area of 190.9 cm2) 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 H2 is reported 40.4 L h–1, thereby being equivalent to electricity produced by H2 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.
