Gas Diffusion Layers for MEAs
Mott gas diffusion layers can be tailored specifically to your application to provide you the best performance in terms of mass transport, conductivity, and materials compatibility. Our sheet can be customized in terms of porosity, thickness, and rigid contact surface depending on your needs. Additionally, Mott has the most extensive material selection in the industry ranging from titanium for standard applications, nickel 200 and 430 SS for SOFCs, and specialty alloys such as niobium for aerospace. For customers working on gas generation applications, Mott supplies PTLs down to .010″ thinness for better reaction times.

- Rapid Prototyping Cell – Trying to determine the feasibility of your design as fast as possible? Use our rapid prototyping cell to turn around prototypes in as little as 2 weeks. Our engineers will work with equipment similar to our manufacturing facility to provide with you with manufacturable, economical design.
- Additive Manufacturing – If you’re looking for the most uniform porosity or a non-traditional design, look no further than working with out porous 3D printing team. We can create controlled porosity designs with various density gradients in non-traditional shapes to satisfy the most unique design request. Our technology allows us to print parts with both solids and porous in a single print cycle
Lab Testing – If you need data packages or feasibility testing for your part prior to installation, we’re happy to work with you. We’ll use our lab center to perform various characterization and performance tests to ensure your parts are meeting strict specifications prior to you receiving them.
Computational Fluid Dynamics – If you would like to model your process fluids interaction with your Mott requested part, ask your Mott representative how we can model it using CFD software.
Engineering Memberships – If you’re constantly working on complex designs that require the highest standards of engineering support, ask about our membership rates to our lab, which will allow you discounted rates to various lab testing, prototyping, and engineering resources.
