Titanium Fiber Felt
Sintered pure titanium fiber felt — primary specification is the porous transport layer (PTL) in PEM water electrolyzers. Porosity 40–80% (60–70% standard), pore size 5–80 µm.
Titanium Fiber Felt
The primary market is PEM water electrolysis. Titanium fiber felt is one option for a PEM anode porous transport layer (PTL). Confirm suitability for the cell design, contact resistance, coating requirements and operating conditions; it is not the only available PTL structure. FILTURE supplies single-layer felt and multi-layer felt assemblies in thicknesses from 0.1 mm to 6 mm, cut to cell dimensions or in sheet rolls up to 1200 × 1200 mm for customer die-cutting.
For fuel-cell applications, coatings or bonded composites, submit the drawing and operating conditions for review. Availability, dimensions, treatment specification and application suitability require written confirmation before quotation or ordering; these are not confirmed standard supply options.
Secondary applications include pharmaceutical clarification, food processing, and high-temperature gas filtration, where the high void volume (40–80%, 60–70% standard) gives low pressure drop at high flow rates and good dirt-holding capacity.

What Makes Titanium Fiber Felt Reliable
PEM Anode PTL Selection
Titanium fiber felt is one option for a PEM anode porous transport layer (PTL). Confirm suitability for the cell design, contact resistance, coating requirements and operating conditions; it is not the only available PTL structure.
40–80% Porosity
High void volume enables simultaneous electron conduction, water ingress to membrane, and oxygen escape — the competing mass transfer requirements of the PEM anode PTL.
Pore Size and Thickness by Specification
Pore size 5–80 µm, thickness 0.1–6 mm — specified to the individual cell design. Multi-layer assemblies for gradient porosity structures on request.
Material Compatibility
Confirm material compatibility for the actual medium, concentration, temperature and operating conditions before ordering. Titanium is not specified here as universally resistant to hydrochloric or sulfuric acid.
Surface Treatment Review
Specify the intended surface treatment and its purpose. Coating availability, loading, conductivity, wettability and effects on porosity must be reviewed and confirmed; no standard platinum or PTFE treatment is promised here.
Composite Design Review
Submit the proposed layer structure, dimensions and joining requirements. Feasibility, supply capability and application performance must be confirmed; a diffusion-bonded felt-plate composite is not a confirmed standard offering.
Where Titanium Fiber Felt Is Specified
PEM Water Electrolyzer — Anode PTL
Porous transport layer on the anode side of a PEM water electrolyzer. It supports water supply, oxygen removal and electrical contact with the adjacent cell components. Suitability depends on the cell design and operating conditions.
0.3–2 mm thick · Custom cell dims · TiPEM Fuel Cell — Anode Side
Gas diffusion medium in hydrogen fuel cell anodes. Ti felt used in applications where high corrosion resistance is needed.
Custom thickness · 20–40 µm fiberFuel Cell Application Review
Fuel-cell use requires evaluation of the electrode environment, operating temperature, surface treatment and contact resistance. Suitability as a cathode gas diffusion layer and supply specifications are not confirmed and require application-specific validation.

Submit the proposed layer structure, dimensions and joining requirements. Feasibility, supply capability and application performance must be confirmed; a diffusion-bonded felt-plate composite is not a confirmed standard offering.
Subject to written technical and supply confirmationAlkaline Electrolyzer Components
Ti fiber felt for electrode and separator support in alkaline electrolyzers — stable in KOH electrolyte at elevated temperature.
KOH-compatible · 1–5 mm · CustomPharmaceutical Clarification
Sintering joins the metal fibers. Particle and fiber release must be assessed under the specified operating, cleaning and backwash conditions; no zero-shedding guarantee is made.
5–50 µm · TiFood and Beverage Filtration
Pharmaceutical and food-contact suitability must be assessed for the finished component and intended use. Material grade alone does not establish biocompatibility or regulatory compliance; agree the required evidence before ordering.
5–50 µm · Application validation requiredHigh-Temperature Gas Filtration
High-porosity Ti felt for hot-gas filtration where the 300 °C rating and chemical resistance of titanium are needed.
