Energy Materials
Materials designed for the long-term operation of water electrolysis stacks.
LT Metal PTL materials maximize the hydrogen production efficiency of water electrolysis stacks.
The PTL (Porous Transport Layer) used in PEM water electrolysis stacks is a key component that significantly affects both stack performance and service life. Compared with conventional PTLs, LT Metal’s PTL features lower surface roughness, a uniform open-pore structure, and high strength.
