Product Description

Lightweight Titanium Fiber Felt 3D Porous Structure for Battery Electrodes Catalysts

Titanium Fiber Felt Description
Titanium fiber sintered felt is made of drawn titanium fibers with a diameter of micrometers, which are finely spun and sintered at high temperatures. It can withstand extremely high temperatures (>300 ºC) and maintain micro pore stability. The felt has a multi-layer structure with gradient distribution of micron pores, which has extremely high filtration accuracy.
The Ti series titanium fiber felt is a pure titanium substrate with extremely high purity. After surface coating processing, it forms an insoluble anode PSA with excellent performance. Compared with graphite fiber felt, it has higher current density and service life, especially for high-temperature  performance.

Titanium Fiber Felt Applications
Widely applicable for hydrogen fuel cells (high-temperature type) gas diffusion layer, liquid flow battery anode GDL reaction layer, PEM electrolysis hydrogen production anode GDL substrate.

High temperature sintering: Titanium fiber sintered felt is made of titanium fibers with a diameter of micrometers, stacked and sintered at high temperature. Multi layer titanium fiber felt is composed of layers with different pore sizes to form a gradient of pore size, which can be controlled to achieve extremely high filtration accuracy and a larger pollutant capacity than single layer felt.

Excellent performance: The sintered felt is made of pure titanium fiber material, which gives it excellent performance, including high temperature resistance, corrosion resistance, acid and alkali resistance, wear resistance, conductivity, and a series of comprehensive properties that are significantly superior to other types of filter materials such as sintered metal powder, ceramics, other fibers, filter cloth, filter paper, etc.

FAQ

1. Q: Why choose titanium fiber felt over carbon felt for electrolyzers?
A: Titanium fiber felt is oxidization-resistant, making it ideal for the oxygen-evolving anode side, where carbon felt degrades into CO₂/carbonates. It ensures long-term stability in acidic/alkaline environments, unlike carbon materials.

2. Q: Does titanium fiber felt require a coating for optimal performance?
A: While bare titanium works, a platinum (Pt) coating significantly enhances conductivity and reduces interfacial resistance, improving electrolyzer efficiency. Other coatings (e.g., IrO₂) can also be applied for specific needs.

3. Q: What thickness and porosity options are available?
A: Standard thickness: 0.2-3.5 mm (customizable). Porosity ranges from 50-90%-higher porosity improves gas diffusion, while lower porosity increases mechanical strength.

4. Q: Can you provide custom sizes or shapes for stack integration?
A: Absolutely! We supply:
Standard sheets (e.g., 100 × 100 mm to 1 × 1 m).
Custom-cut shapes (circles, trapezoids for bipolar plates).
Integrated GDL/catalyst layers (pre-coated with IrO₂, etc.).

5. Q: MOQ? 
A: Low minimum order quantities for R&D; bulk discounts for production.

6. Q: Lead Time? 
A: 2-3weeks (stock items ship in 5 days).
