Membrane for alkaline water electrolysis is an advanced material developed by combining Nippon Shokubai's organic-inorganic composite technology and sheet-manufacturing technology. This innovative membrane is a key component in alkaline water electrolyzers, which split water (H₂O) into hydrogen (H₂) and oxygen (O₂) using an electric current in an alkaline environment. Hydrogen produced through water electrolysis using renewable energy is seen as a clean and sustainable energy source, crucial for achieving carbon neutrality.
Key Features
- High Ionic Conductivity: Nippon Shokubai’s membrane is engineered to offer excellent ionic conductivity, allowing efficient transfer of hydroxide ion (OH⁻) between the anode and cathode during the electrolysis process. This results in higher efficiency and lower energy consumption.
- Excellent gas barrier properties: In alkaline water electrolyzers, gas separation between generated H₂ and O₂ is crucially important for safe operations. The membrane shows excellent gas barrier properties.
- Chemical and Thermal Stability: Our membrane is designed to withstand the harsh alkaline conditions typically found in electrolyzer cells, as well as high operating temperatures. Its durability ensures long-lasting performance in industrial applications.
- Dry state: Our membrane is provided in dry state. This feature makes it easy to transport, store and handle.
Applications
Nippon Shokubai’s membrane is designed for use in alkaline water electrolyzers deployed in hydrogen production facilities, renewable energy storage systems, and industries seeking to decarbonize their processes by switching to hydrogen as a clean fuel source.
