Product Description 1.Product Introduction Perfluorosulfonic acid membranes are advanced solid polymer electrolytes, consisting of homogeneous membranes with ion exchange functional groups derived from perfluorosulfonic acid resin. These membranes exhibit outstanding heat resistance, mechanical strength, and electrochemical properties, making them ideal for use in extreme conditions such as exposure to strong acids, bases, and oxidizers. Their exceptional chemical stability and durability enable their application in various high-performance electrochemical devices, including Proton Exchange Membrane (PEM) water electrolyzers. This technology is widely used for hydrogen production, fuel cells, and other energy storage systems where reliability and efficiency are critical.2.AdvantagesSuperior Chemical Stability: Perfluorosulfonic acid membranes are designed to withstand harsh environments, including exposure to strong acids, bases, and oxidizing agents, ensuring long-term stability and performance in demanding applications.Excellent Heat Resistance: These membranes maintain their structural integrity and functional properties at elevated temperatures, making them suitable for high-temperature electrochemical processes.High Mechanical Strength: The membranes possess a robust mechanical structure that resists deformation under stress, ensuring consistent performance over extended operational periods.Enhanced Electrochemical Performance: With high ionic conductivity and low electronic conductivity, these membranes facilitate efficient ion transport while minimizing energy loss, making them ideal for energy-intensive applications like PEM water electrolyzers.Wide Applicability: Due to their versatile properties, perfluorosulfonic acid membranes are used in various fields, including hydrogen production, fuel cells, and other advanced energy systems, contributing to the development of sustainable energy solutions.3.Product Parameters Membrane TypeThickness (microns) (μm)Weight (g/m2)Physical and Other Properties 5199.0Index ParametersTensile Strength (M Pa): ≥30Tensile Modulus (M Pa): ≥400Elongation at Break (%): ≥120Specific Gravity: 1.97Other Properties Index ParametersConductivity (S/cm)≥0.100 Acid Capacity (meq/g)/ Hydrolytic Property Index ParametersWater Content (%)5.0±3.0 Water Uptake (%)50.0±5.0 Thickness Swelling Rate (23°C, 50% RH), % increaseWater soaked at 23°C, 50% RH: ≤5 Water soaked at 100°C, 50% RH: ≤15 Linear Expansion (23°C, 50% RH) % increase/ Water soaked at 23°C, 50% RH: ≤5 Water soaked at 100°C, 50% RH: ≤18 4.Application-Vanadium Flow Battery
