Against the backdrop of global New energy transition and strict environmental protection regulations, perfluorosulfonic acid ion exchange membranes have emerged as a critical material in high-value industrial processes. Thinkre Membrane Material Co., Ltd. (Suzhou) has leveraged advanced synthesis technology to develop high-performance perfluorosulfonic acid ion exchange membranes, which are widely applied in hydrogen fuel cells, electrolysis, water treatment, and other key sectors, delivering reliable performance for global clients.

Hydrogen Fuel Cells: The "Proton Bridge" for Clean Power

In hydrogen fuel cell systems—whether for automotive, stationary power generation, or portable energy devices—Thinkre’s perfluorosulfonic acid ion exchange membrane acts as an irreplaceable "proton bridge." Its highly fluorinated backbone ensures exceptional chemical stability, resisting degradation from hydrogen peroxide and high-temperature environments. The sulfonic acid functional groups, when wetted, form continuous proton-conducting channels, enabling fast H⁺ transfer while strictly isolating hydrogen and oxygen gases. This dual function guarantees efficient power conversion (with proton conductivity up to 0.1 S/cm) and long-term durability (over 10,000 operating hours), making it a preferred choice for fuel cell manufacturers worldwide.

Electrolysis: Boosting Efficiency in Chlor-Alkali & Green Hydrogen

The electrolysis industry relies heavily on the superior performance of perfluorosulfonic acid ion exchange membranes. In chlor-alkali production, Thinkre’s membrane effectively separates the anode and cathode chambers, allowing Na⁺ ions to pass through while blocking Cl⁻ and OH⁻ migration. This prevents unwanted side reactions, increasing caustic soda purity to over 99% and reducing energy consumption by 15-20% compared to traditional diaphragm methods. For green hydrogen production via PEM electrolysis, the membrane’s resistance to strong oxidants and high current density compatibility (up to 2 A/cm²) ensures efficient water splitting, producing high-purity hydrogen (≥99.99%) that meets industrial and fuel cell standards.

Water Treatment & Beyond: Precision Separation for High Purity

In water treatment scenarios such as electronics-grade ultrapure water preparation and PFAS-contaminated water remediation, Thinkre’s perfluorosulfonic acid ion exchange membrane excels at precision separation. Its selective ion conduction enables efficient removal of trace metal ions (e.g., Cu²⁺, Ni²⁺) and organic pollutants, ensuring water quality meets SEMI C12 standards. Additionally, the membrane finds applications in electrodialysis for food processing (e.g., desalination of soy sauce) and pharmaceutical industry (purification of active pharmaceutical ingredients), where its chemical inertness and low extractables avoid product contamination.

Thinkre’s perfluorosulfonic acid ion exchange membrane stands out for its customizable thickness (12-260 μm), and consistent batch-to-batch performance. It has gained trust in New energy, chemical, and environmental protection industries. Whether for redox flow battery, fuel cell stacks, electrolyzers, recover copper from Etch solution, remove impurity ions, produce ozoneor, or water treatment systems etc, Thinkre delivers tailored membrane solutions to drive your operational efficiency.
