Multi‐arm Branched Poly(carbazole‐aryl piperidinium) Anion Exchange Membrane with High Conductivity and Good Alkaline Stability for Fuel Cells

Chinese Journal of Chemistry, Journal Year: 2025, Volume and Issue: unknown

Published: March 19, 2025

Comprehensive Summary The lack of anion exchange membranes (AEMs) with good conductivity and alkaline stability has been one the challenges for fuel cells. Introducing branched structure was a strategy to promote due bigger free volume polymer steric hindrance cation. Herein, series AEMs multiple arms (four six) were successfully prepared. Multi‐arm demonstrated obvious improvement because larger multi‐arm structures, respectively. Four‐arm B4‐QPPCTP‐5 exhibited best comprehensive performance, including high 242.2 mS·cm –1 , 2000 h hardly degradation, mechanical property >40 MPa. Single cell based on power output 1.2 W·cm –2 . This work provides effective theoretical guidance design preparation AEMs.
