3. Pretreatment method (recommended)


DuPont pointed out: n117 membrane can be pretreated before use, the specific methods are as follows:


Firstly, 5% hydrogen peroxide was treated at 80 ℃ for 1h, then soaked in deionized water for half an hour, then 5% dilute sulfuric acid (mass ratio) was boiled at 80 ℃ for 1h, and finally soaked in deionized water for half an hour.


Or according to the user's established habits, it can only be used after immersion of electrolyte solution.


4. General description


describe


DuPont ä Nafion ® PFSA membrane is a non reinforced membrane based on Nafion ® PFSA polymer in the form of acid perfluorinated sulfonic acid / PTFE copolymer (H +). Nafion ® PFSA membrane is widely used in proton exchange membrane (PEM) fuel cells and water electrolyzers. The membrane serves as a separator and solid electrolyte for the electrochemical cell to connect selective transport cations in the whole cell in various kinds of required membranes. The polymer is chemically resistant and durable.

For and packaging information

The film size is based on the relative humidity of 23 ℃ and 50% before the dry product cutting. The water content of the film will affect its size and change may not be symmetrical in length, width and thickness direction. In addition, some adjustment steps performed by the customer can also affect the dimensions
