Fuel Cell Membranes
IMS: International Marketing Services
IMS is partnered with a US manufacturer of fuel cell membranes that has developed a unique design and manufacturing process for polymer electrolyte membrane electrode assemblies (MEAs) used in hydrogen fuel cell applications. Utilizing over 40 years of experience in working with Dupont's NAFION® membrane, IMS is able to offer a process that delivers low resistance, durable and consistently high performing MEAs for PEM fuel cell applications. The product line of membrane electrode assemblies offers the following advantages.
HIGH POWER DENSITY
Ultra-thin (<30 micron) unreinforced NAFION® containing membranes result in high power density, low resistance structures.
MOST COST EFFECTIVE
Membrane where you need it, not where you don't.
MOST DURABLE
N-111-IP tested by General Motors to be the longest lasting commercially available fuel cell membrane. IMS offers an MEA manufacturing line that utilizes state-of-the-art continuous roll-roll coating operations that are set up to handle the prototype and high-volume production requirements of today's growing PEM fuel cell industry. So whether you need one or thousands of catalyst coated membranes for hydrogen fuel cells or water electrolyzers, contact IMS to discover how your application can be "turned on" by catalyzed membranes.
Catalyzed Coated Membranes offer the following advantages:
- 20 to 30 micron thick membrane component for high power density
- Membrane component containing the stable NAFION® ionomer resulting in long component life
- Unique fabrication method allows the perimeter area (outside of the active region) to be substituted with a strong material for sealing integrity, durability, and reduced cost.
- DuPont™ NR-111, -25µm, 1100EW NAFION®
- N-111-IP, -25µm
- Gore™ Primea® Series 57
- Pellets
- Used for acid catalysis of many organic reactions. Product names include: NR40 (1000 EW polymer) and NR50 (1100 EW polymer). The product is also available in its precursor form as R1100 and R1000. For more details and pricing on these products please submit a product inquiry.
- Non-Reinforced Films
- These films are used as separators in electrochemical cells requiring high ionic conductivity, for example in fuel cells and water electrolyzers. Product names include: N111-IP, N115, N117, and N1110. For more details and pricing on these products please submit a product inquiry.
- Cast Films
- DuPont™ NAFION® PFSA NR-211 and NR-212 membranes are non-reinforced dispersion-cast films based on chemically stabilized perfluorosulfonic acid/PTFE copolymer in the acid (H+) form. The physical properties remain the same for the stabilized membranes , which exhibit substantially lower fluoride ion release compared to the non-stabilized polymer - a sign of improved chemical durability. NAFION® 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.
- Fabric Reinforced Membranes
- These reinforced films are typically used in industrial sized electrochemical applications with large areas (typically in square meters) where membrane strength is required. Product names include N324 and N424. Please submit a product inquiry. for technical information related to these products.
- Polymer Dispersions
- The NAFION® polymer is dissolved in a dispersion which can be used for casting films or manufacturing other products containing NAFION® polymer. Available products include: D520, D521, D1020, D1021, D2020, and D2021. D dispersions are manufactured by DuPont™ and distributed by IMS on a global basis.
