Product Bulletin P-12 N115, N117, N1110 Ion Exchange Materials Extrusion Cast Membranes Product Information NafionTM perfluorosulfonic acid (PFSA) membranes are non-reinforced films based on chemically stabilized PFSA/polytetrafluoroethylene (PTFE) copolymer in the acid (H+) form. The physical properties remain the same for the chemically stabilized membranes, which exhibit substantially lower fluoride ion release compared to the non-stabilized polymer—a sign of improved chemical durability. NafionTM PFSA membranes are widely used for proton exchange membrane (PEM) fuel cells and water electrolyzers. 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. Order and Packaging Information Membrane dimensions are based on dry product conditioned at 23 °C (73°F) and 50% relative humidity (RH) before cutting. The membrane’s water content will affect its dimensions, and the change may not be symmetrical in the length, width, and thickness directions. In addition, certain conditioning steps performed by the customer also may affect the dimensions. Customers may wish to review their membrane treatment steps and dimensional requirements with a NafionTM technical representative before establishing membrane shipping dimensions. Contact Us: www.fuelcellstore.com sales@fuelcellstore.com (979) 703-1925 Standard dry product dimensions for individual pieces include: Width: 0.30 m (min.) to 1.22 m (max.) Length: 0.30 m (min.) to 1.22 m (max.) The membrane delivery package for cut pieces will depend on the size and quantity of the membrane order. Smaller sized membranes are shipped flat, while longer lengths of individual pieces are shipped on a roll. The membranes are protected with a polyethylene wrap and inner packaging, and then placed in shipping containers. Standard dry product dimensions for roll goods include: Width: 12-in (0.305-m) and 24-in (0.610-m) standard roll widths, and roll widths from 0.20-m (min.) up to 1.22-m (max.) on special order. Intermediate widths available in increments of 0.125-in Length: 50-m standard roll length There is a 100 m2 minimum order requirement for non- standard roll widths and lengths. Membrane pieces or rolls can be cut to custom sizes, and special packaging provided at additional cost and/or delivery time. Please contact NafionTM Customer Service for details.

CO2 Phase Change Demonstrator: Experiment with gas to liquids (CO2 to alcohol) using Nafion and our phase change demonstrator cart (we can ship worldwide)... More Info

CO2 GTL Gas to Liquids Experimental Platform: Experiment with gas to liquids (CO2 to alcohol) using Nafion (electrolyzer membrane) and our phase change demonstrator cart (we can ship worldwide). CO2 goes supercritical at 31 C. This is a experimental platform which you can use to demonstrate phase change with low heat. Includes integration area for small CO2 turbine, static generator, Nafion pellets, Nafion membrate, or Nafion tubes... More Info

Concept: The concept of the SeaMerlin Engine is to convert or supplement existing marine vessel propulsion to a gas leverage turbine which scavenges CO2 from saltwater at the same time it provides vessel thrust.
