Product Overview
The anion exchange membrane is a high-performance, homogeneous membrane material designed for demanding applications. It offers high ionic conductivity, robust mechanical strength, and excellent chemical stability. This membrane material is widely used in water electrolyzers, alkaline fuel cells, and CO₂ reduction systems. It is engineered to perform efficiently under high temperature and alkaline conditions, providing long-term durability and reliable performance.
Product Features
High Ionic Conductivity: At 80°C and 100% relative humidity (RH), the W-75 membrane achieves an ionic conductivity of ≥130 mS/cm, and the W-25 membrane reaches ≥150 mS/cm, ensuring superior electrolysis efficiency.
High Mechanical Strength: Tensile strength ≥30 MPa, preventing breakage or damage during use.
Excellent Alkaline Stability: In 1M NaOH solution, the membrane maintains its structure without degradation even after soaking for 10,000 hours at 80°C. The main chain degradation is minimal, and the cation degradation is less than 5%, ensuring stable long-term operation.
Low Swelling Rate: The membrane material exhibits a swelling rate of ≤20% in pure water at 80°C, helping to maintain its dimensional stability.
Wide Temperature Range: The membrane operates efficiently within a temperature range of 20°C to 80°C, making it suitable for various industrial applications.
