Key Points

This research aims to optimize pore size in covalent organic frameworks to enhance the performance of anion exchange membranes.
Engineered pore sizes in covalent organic frameworks.
Evaluated membrane performance in electrolytic cells during hydrogen production and fuel cells.
Measured ion exchange capacity and gas permeability.
Pore size optimization led to a 20% increase in ion exchange capacity (p<0.01).
Improved gas permeability by 15% compared to standard membranes (p<0.05).
Enhanced overall membrane performance demonstrated through higher efficiency in electrolytic cells (p<0.001).

Implication

Demonstrates enhanced ion exchange in anion exchange membranes, indicating improved performance in hydrogen production.

Abstract

Anion exchange membranes (AEMs) play a crucial role as separators in electrolytic cells, facilitating gas isolation and ion exchange during hydrogen production via water electrolysis and in fuel cells. To...
