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.

Literature & Data Sheets
For engineering and manufacturing applications, the results of electrolysis are limited by the quality of the equipment and processes used. Efficient, consistent electrolysis requires finely calibrated, intelligently designed equipment. Oftentimes, getting the right results is a matter of having the correct porous transport layers – or PTLs – for your particular electrolysis applications. PTLs are thin components in an electrolytic cell, typically made of titanium foil and built with a highly specific porous structure. These titanium porous transport layers provide the ideal surface area and flowage for use in high-end electrolysis applications.

Porous Transport Layer (PTL) Case Study
Mott Porous Transport Layers achieve high power densities in gas generation applications due to a proprietary ultra-thin design resulting in better mass transport and a smaller footprint.
Titanium Sheet Quality Standards
Mott Corporation's acceptance criteria for ultra-thin sheet used in PEM electrolyzers. For a titanium sintered porous sheet to remain usable and reliable in a high-intensity porous transport layer application the titanium must be of a very specific quality. Mott’s experts have an in-depth understanding and knowledge of titanium and the other materials we use to build the custom high-end porous transport layer systems that contribute to the success of our partners’ projects.
