Perfluorosulfonic NC700 Proton / Cation Exchange Membrane Fuel Cell

Description: 1. Introduction• Nafion NC700 membrane is based on chemically stabilized perfluorosulfonic acid (PFSA)/polytetrafluoroethylene (PTFE) copolymer in the acid (H+) form, which is reinforced and exhibits substantially lower fluoride ion release compared to non-stabilized polymers—a sign of improved chemical durability. • Nafion PFSA membranes are proton exchange membranes (PEMs) that are used for various applications, including but not limited to fuel cells, water electrolyzers, and flow batteries. The membrane performs as a separator and solid electrolyte in a variety of electrochemical cells that require the membrane to selectively transport cations across the cell junction. • The polymer is chemically resistant and durable. The membrane is positioned between a backing film and coversheet. This composite is wound on a 6 in ID plastic core, with the backing film facing out, as shown in Figure 1. A 6 in ID plastic roll core is standard. • The 3.0 mil backing film facilitates transporting the membrane into automated fabrication processes, while the 0.92 mil coversheet protects the membrane from exposure to the environment during intermediate handling and processing. In addition, the coversheet (in combination with the backing film) eliminates rapid changes in the membrane’s moisture content and stabilizes the dimensions of the membrane as it is removed from the roll.• The water content and conditioning of the membrane will affect its dimensions, and the change may not be symmetrical in the length, width, and thickness directions. Once the coversheet is removed, the membrane will respond to the environmental conditions of the workplace. If the membrane remains on the backing film, the membrane’s response to relative humidity (RH) conditions, for example, may cause the combination of membrane/ backing film to curl.• In addition, certain manufacturing steps performed by the customer also may affect the membrane’s dimensions and flatness. If specified in the purchase order, a roll core leader is attached to the membrane as shown in Figure 2. The roll core leader material is the same as the backing film and the length specified in the purchase order.
