Proton exchange membranes, MEAs and original Nafion™ on request for professional applications, research and development.
Costruzioni Energetiche offers the supply of PEM/PFSA membranes and components for fuel cells and electrolyzers, intended for companies, labs, universities, research centers and developers of hydrogen technologies.
Proton exchange membranes are available in various thicknesses and configurations, as well as MEAs (Membrane Electrode Assemblies) that can be made to different active areas and specifications.
For applications that expressly require original material, it is also possible to request the supply of original Nafion™ membranes.
Formats, quantities and quotations are defined according to the project specifications.
PEM/PFSA Membranes
PEM (Proton Exchange Membrane) proton exchange membranes based on PFSA polymers are used as a solid electrolyte in numerous electrochemical applications.
Their function is to enable proton transport while keeping the reactants separated, a key feature in PEM Fuel Cell and PEM Water Electrolysis technologies.
Main applications include:
PEM Fuel Cell • PEM Electrolyzers • Hydrogen production • Electrochemical systems • Prototyping • Laboratory testing • Research and development
The availability of different thicknesses makes it possible to select the membrane according to the characteristics required by the application.
Available membranes
Sizes, formats and quantities available on request.
PEM/PFSA Membrane N-117
Among the available configurations, the N-117 is a solution for PEM applications that require a thicker PFSA membrane.
According to the technical data provided by the manufacturer, it features:
Typical thickness: 183 μm
Basis weight: 360 g/m²
Conductivity: 0.083 S/cm
Acid capacity: 0.89 meq/g
Specific density: 1.98
The technical documentation also reports a typical water content of 5% and a water uptake of 38%, with dimensional and mechanical properties assessed according to different ASTM methods.
The complete technical documentation can be provided upon request.
Note: the PFSA N-117 membrane described here is not Chemours Nafion™ N117. For projects that specifically require original Nafion™, a dedicated supply service is available upon request.
Original Nafion™ on request
For applications, research activities or project specifications that explicitly require the use of original Nafion™, Costruzioni Energetiche can also handle dedicated supply requests.
Different types of Nafion™ membranes for PEM applications are available on request, depending on thickness, dimensions, quantity and intended use.
Looking for Nafion™ N115, N117, NR211 or NR212?
Send us the product code, the format and the required quantity.
We will check availability and pricing through our supply channels.
MEA – Membrane Electrode Assembly
In addition to PEM/PFSA membranes, the supply of MEA – Membrane Electrode Assembly is available for fuel cell applications.
MEAs combine membrane and catalyzed electrodes, forming the electrochemical core of the cell.
Available configurations include:
Membrane thickness: 50 μm
Active area: 5 cm² • 16 cm² • 25 cm² • 50 cm² • 100 cm²
Catalyst loading:
Anode: 0.5 mg Pt/cm²
Cathode: 0.5 mg Pt/cm²
Available configurations:
3-layer • 5-layer • 7-layer
For specific needs, you can request a custom configuration, indicating number of layers, active area and, if applicable, providing the MEA technical drawing.
B2B and R&D
Costruzioni Energetiche works with companies, labs, universities, research centers, integrators and PEM system developers who need membranes and components for experimental activities, prototyping or professional applications.
We can handle requests related to:
PEM/PFSA membranes • original Nafion™ • MEA • different sizes and thicknesses • samples and small quantities • B2B supplies • components to specification
So it is not necessary to identify the exact product in advance.
If you are developing a fuel cell, an electrolyzer or an electrochemical application, you can send us directly the material characteristics you are looking for.
