Electrolytic Hydrogen Production Membrane

Product Overview

The water electrolysis hydrogen separation membrane is a critical component in alkaline water electrolysis systems, enabling efficient ion transport while effectively isolating hydrogen and oxygen gases. This prevents gas crossover, improves electrolysis efficiency, and extends equipment lifespan. The membrane features a composite structure of organic polymers, ceramic powders, and an internal support layer, designed specifically for alkaline water electrolysis, combining high separation performance with long-term stability.

Working Principle

The membrane forms ion-conducting channels through its composite structure, allowing rapid migration of hydroxide ions in the electrolyte while physically blocking direct contact between hydrogen and oxygen gases. Its permanent hydrophilicity ensures stable conductivity under electrolyte immersion. High bubble point pressure and low ionic resistance (≤0.3 Ω·cm² at 30 °C, 30 wt.% KOH) guarantee efficient electrolysis and system safety. The internal support layer enhances mechanical strength, maintaining dimensional and performance stability in high-concentration alkaline environments over long-term operation.
