Porous Transport Layers for Electrolysis

For customers working on electrolysis applications, such as hydrogen generation, Mott supplies titanium porous transport layers as thin as .010″, resulting in lower oxidation rates, smaller footprints, and better resistance to bending and cracking. This material is widely used in applications such as on-site gas generation and mega stacks. Thin Ti sheets are available in many sizes and can be coated with various catalysts, such as platinum, to improve conductivity and oxidation resistance. In addition to titanium, Mott offers other alloys for different applications. We also supply product in small quantities for single cell testing.

High-quality PTLs, such as those manufactured using a titanium sintered porous sheet method, play a crucial role in determining the performance of your anode. For use in high-performance electrolysis, we recommend using Mott’s thin titanium sinters in combination with thin, compatible membranes.
