TOPTITECH 0.1mm ultra-thin titanium felt is specially engineered as a core porous material for Proton Exchange Membrane (PEM) water electrolysis systems, setting a new benchmark for efficiency and durability in hydrogen production. Crafted from high-purity Grade 1 titanium fiber via advanced vacuum sintering technology, this ultra-thin felt features a uniformly controlled porous structure with ultra-fine pore size distribution, ensuring optimal gas-liquid mass transfer and minimal electrical resistance - critical factors for boosting the overall energy efficiency of PEM electrolyzers.

Designed for the rigorous demands of electrolysis applications, our 0.1mm titanium felt excels in multiple core functions within the PEM electrolyzer stack. As a key Porous Transport Layer (PTL) and gas diffusion substrate, it facilitates the rapid transport of hydrogen and oxygen while preventing membrane dehydration, maintaining stable operation even under high current density conditions. Its exceptional corrosion resistance safeguards against acidic electrolytes and oxidative environments, eliminating the risk of material degradation and extending the service life of the electrolysis system. Additionally, the ultra-thin profile (0.1mm) reduces ohmic loss, lowering power consumption and operational costs for large-scale hydrogen production projects.

Products Features

06mm Thickness Titanium Fiber Felt in Drawing Process 5

1. Ultra-Thin 0.1mm Structure for Minimal Ohmic Loss

At only 0.1mm thick, this titanium felt significantly reduces internal resistance in PEM electrolyzer stacks. Its ultra-slim profile lowers ohmic heat generation, improves energy utilization efficiency, and supports higher current density operation-critical for enhancing overall hydrogen production performance.

2. Optimized Porosity 60–80% for Superior Mass Transfer

Engineered with a stable porosity range of 60–80%, the material delivers exceptional gas‑liquid transmission performance. It ensures uniform distribution of water and rapid discharge of generated H₂ and O₂, prevents flooding or drying of the membrane electrode assembly (MEA), and maintains long‑term stable stack operation.

3. High-Purity Grade 1 Titanium Construction for Exceptional Corrosion Resistance

Made from high‑purity Grade 1 titanium through precision vacuum sintering, the felt exhibits outstanding corrosion resistance in strong acidic and oxidative PEM operating environments. It avoids degradation, rust, or fiber shedding, greatly extending the service life of electrolysis components.

4. Excellent Electrical Conductivity with Uniform Current Distribution Performance

The three‑dimensional continuous fibrous network ensures excellent electrical conductivity and even current distribution across the electrode surface. This boosts catalytic reaction efficiency, reduces hotspots, and improves the stability and durability of the entire electrolysis system.

applications

1. Porous Transport Layer (PTL)

As the primary functional component in PEM electrolyzer stacks, titanium felt serves as a critical Porous Transport Layer (PTL) positioned between the electrode catalyst layer and the bipolar plate.

Efficient Mass Transfer: Facilitates the rapid flow of liquid water to the reaction site and the immediate discharge of generated hydrogen/oxygen gas, preventing issues like membrane flooding or dehydration.

Uniform Current Distribution: Its high electrical conductivity ensures even current distribution across the electrode surface, enhancing reaction efficiency and preventing hotspots.

Mechanical Support: Provides structural stability under the high pressure and temperature conditions within the electrolyzer.

2. Catalyst Support Substrate

Titanium felt acts as an ideal high-surface-area scaffold for loading precious metal catalysts (such as Iridium, Ruthenium, or Platinum) on both the anode and cathode.

Maximized Catalyst Utilization: The 3D interconnected porous network offers a large specific surface area, ensuring catalysts are fully exposed to the electrolyte and reactants.

Enhanced Durability: The corrosion-resistant Grade 1 titanium structure securely anchors the catalyst layer, preventing particle shedding and degradation during long-term operation in harsh acidic/oxidative environments.

3. Gas Diffusion Layer (GDL)

For high-current-density PEM electrolysis systems, titanium felt functions as a precision Gas Diffusion Layer (GDL) integrated into the Membrane Electrode Assembly (MEA).

Uniform Dispersion: It ensures the homogeneous distribution of reactant water and product gases, minimizing local concentration polarization and boosting overall hydrogen production efficiency.

Dynamic Adaptability: Its flexible nature adapts to assembly pressures, maintaining reliable contact and gas-liquid exchange within the MEA.
