Product Overview
The electrolytic hydrogen production membrane is a crucial component in the water electrolysis process for hydrogen production. Serving as a separator in electrolysis cells, this membrane enables efficient ion transmission while effectively isolating hydrogen and oxygen to prevent gas cross-mixing. This enhances electrolysis efficiency and prolongs the equipment's lifespan. Carbon Energy Technology’s new composite membrane material is specially designed for "alkaline water electrolysis hydrogen production" with a composite structure of organic polymers, ceramic powder, and an internal support layer, optimized for high-efficiency gas separation.
Product Features
Permanent Hydrophilicity: Strong electrolyte wettability ensures stable performance over time.
High Purity: Delivers high gas purity with hydrogen purity reaching 99.9%.
Safety and Stability: High bubble point pressure design ensures operational safety.
Low Ionic Resistance: Surface resistance as low as ≤0.3 Ω·cm² (at 30°C, 30wt.% KOH), enhancing electrolysis efficiency.
Customizable Dimensions: Effective membrane width up to 2.5 meters, customizable to specific customer requirements.
Long Service Life: Exceptional chemical and mechanical stability with a lifespan of over 7 years.
Applications
Alkaline Water Electrolysis for Hydrogen Production: Provides efficient, stable membrane material support for green hydrogen production, widely used in the clean energy sector.
