Robust and ultrathin pore‐filling anion exchange membranes for water electrolysis

AIChE Journal, Journal Year: 2025, Volume and Issue: 71(6)

Published: Feb. 25, 2025

Abstract Ultrathin and robust composite anion exchange membranes are developed by infiltrating poly(biphenyl piperidinium) solution into PE porous substrate overcoming the poor wettability of in a pore‐filling procedure. By strengthening binding between ionomers via physical interlocking strategy, symmetric dense were developed. A representative membrane, namely PE‐PBP‐30%, displays tensile strength exceeding 118 MPa, an elongation at break around 87%, maintains H 2 permeability as low 1.85 Barrer bar. Anion membrane water electrolysis (AEMWE) based on PE‐PBP‐30% could be operated current density up to 800 mA/cm 1.8 V demonstrates stable performance 500 60°C for 600 h with voltage increase rate 0.25 mV/h. This study explores possibility combining traditional homogeneous AEMs diaphragm AEMWE provides insights development AEMWEs using membranes.
