N117 Proton Exchange Membrane Nafion117 Perfluorosulfonic Acid Ion Membrane 3*3cm For Fuel Cell Electrolysis Hydrogen Production

Dear customers proton exchange membranes are available in various sizes of 5*5cm/10*10cm/20*10cm/20*20cm/40*40cm or you can tell me what size you want. Product parameters Brand: Dupont Model: N-117 or N117 or Nafion 117 Thickness: 183um Specifications: 10*10cm Density: 360g/m2 Conductivity: 0.083S/cm Exchange capacity: 0.89meq/g preprocessing method (recommended) Tip: N117 membrane can be pretreated before use. The specific methods are: First 5% hydrogen peroxide was treated at 80 degrees for 1 hour then soaked in deionized water for half an hour; then 5% dilute sulfuric acid (mass ratio) was boiled at 80 °C for 1 hour; and finally soaked in deionized water for half an hour Product introduction Perfluorinated ion exchange membrane and proton exchange membrane produced by the original Dupont company in the United States. Proton Exchange Membrane Pretreatment. It only allows protons (cations) to pass through so it is also called a cation exchange membrane (CEM). use Suitable for electrolyte membranes in fuel cells vanadium batteries electrolyzers electrodialysis electrochemical sensors. Nafion PFSA membranes are widely used in proton exchange membrane (PEM) fuel cells direct methanol fuel cells (DMFC) and water electrolyzers. Functions in electrochemical cells to separate the anode and cathode compartments from the solid electrolyte selectively transporting cations to the cell junction. Nafion N117 N115 NR212 NR211 films are all non-reinforced films with different thickness dimensions. Choosing the right thickness will mainly depend on your desired pressure differential across the membrane (i.e. what kind of hydrogen versus oxygen you will be producing) the type of membrane support and operating life. Nafion membranes are non-reinforced membranes based on chemically stabilized perfluorosulfonic acid/PTFE copolymers in the acid (H+) form. The physical properties of the chemically stabilized membrane remained unchanged and the release of fluoride ions from the chemically stabilized membrane was significantly reduced compared to the non-stabilized polymer. Chemical resistant and durable. Nafion N115 and N117 films have no backing film and cover slip film and can be directly processed or used. characteristic Good thermal stability high temperature resistance; Electrochemical oxidation resistance low corrosion good chemical stability; Good mechanical properties long life; Higher conductivity higher output power.
