Nafion Membrane

Nafion membranes are one of the most common types of PEM membrane used for the creation of a fuel cell. Made of a proton-conductive polymer film, nafion membranes allow only protons to cross-over. Nafion is made from teflon which makes it the most chemical-resistant polymer available.

Core Fuel Cell Component

Nafion can be one of the core components of a fuel cell and is offered in a variety of thicknesses by Fuel Cell Earth. Customers can choose from getting the membrane in its dry state or pre-treated in smaller sizes. Fuel Cell Earth provides Nafion Membrane in 1 mil, 2 mil, 5 mil and 7 mil thickness so our customers can get the right materials for their project. Thinner Nafion membranes are best used in situations where there will be little differential pressure across the membrane and thicker membranes are suited for high pressure applications.

We offer the highest quality Nafion membranes at Fuel Cell Earth. Nafion Membranes are widely used in fuel cells because of their high ionic conductivity. They are used in a wide variety of Fuel Cell applications. Nafion is highly resistant to chemical attack (corrosion resistant) making it a stable option for use in fuel cells. When used as an ion exchange membrane it is specified to operate at temperatures up to 190°C.

Durable Polymer Material

Valued in the fuel cell industry for their durability and high power output, Nafion membranes are the best choice for any size of fuel cell project. Fuel Cell Earth is knowledgable when it comes to handling and storing Nafion. There are still applications for Nafion membrane that have yet to be discovered. Fuel Cell Earth strives to help everyone from beginners to fuel cell experts get the most out of their projects.
