Overview

Engineered diaphragms improve ionic conductivity and gas-blocking in alkaline water electrolysis, suggesting efficiency gains.

Key Points

  • The composite diaphragm achieved an ultralow area resistance of 0.11 Ω·cm², enhancing energy efficiency.
  • At 2 V, the diaphragm reached a current density of 600 mA cm−2, demonstrating high performance for hydrogen production.
  • Stability tests showed functionality over 200 hours at 80°C in 30 wt% KOH solution under constant current conditions.
  • The engineered diaphragm integrates various materials, optimizing hydrophilicity and ionic conductivity for better performance.
