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.
