Proton Exchange Membrane Pretreatment (Pretreatment Proton Exchange Membrane) Uses: Suitable for electrolyte membranes in fuel cells, vanadium batteries, electrolyzers, electrodialysis, electrochemical sensors characteristic: Good thermal stability and high temperature resistance; Anti-electrochemical oxidation, low corrosivity, good chemical stability; Good mechanical properties and long life; High conductivity and high output power.   2, product parameters Brand: DuPont Dupont Model: N-117 or N117 or Nafion 117 Thickness: 183um Density: 360g/m2 Conductivity: 0.083S/cm Exchange capacity: 0.89meq/g   3. Pretreatment method (recommended) DuPont Company Tip: N117 membrane can be pretreated before use, the specific method is: The first mass fraction of 5% hydrogen peroxide is treated at 80 °C for 1 h, then immersed in deionized water for half an hour; then 5% dilute sulfuric acid (mass ratio) is boiled at 80 ° C for 1 hour; finally, it is soaked in deionized water for half an hour, ie can. Or according to the user's established habits, only use the electrolyte solution after soaking,
