Titanium Felt — Porous Transport Layer (PTL) for PEM Electrolyzers
Sintered titanium fibre felt — the industry standard porous transport layer (PTL) for PEM water electrolyzers. The sintered fibre structure provides controlled porosity and tortuosity for uniform water/oxygen two-phase transport at the anode. Platinum-coated (PtTi) titanium felt is available for reduced interfacial contact resistance in high-current-density operation.
