Overview

Randomized trial investigates membrane performance enhancement for hydrogen production, suggesting a new design approach.

Key Points

  • This study aims to improve the performance of composite membranes for alkaline water electrolysis through structural optimization.
  • Introduced amino-functionalized UiO-66 to enhance membrane structure and performance.
  • Evaluated the composite membrane's bubble point pressure, area-specific resistance, and current density under electrolysis conditions.
  • Conducted tests for 600 hours under simulated industrial conditions.
  • The optimal membrane, UDCM-6, achieved a bubble point pressure of 5.72 bar and an area-specific resistance of 0.21 Ω cm2.
  • At 2 V in 10 wt % KOH at 80 °C, a current density of 0.71 A cm–2 was delivered.
  • The electrolysis process remained stable during 600 hours of operation.
