Product Description

Titanium Fiber Felt Description
Titanium fiber felt is made by a special laying process and a special ultra-high temperature vacuum sintering process. Compared with titanium powder sintered plate, Ti fiber felt has an excellent three-dimensional network, porous structure, high porosity, large surface area, uniform pore size distribution, special pressure, and corrosion resistance, and can be rolled and processed. 

Titanium Fiber Felt Applications
Titanium fiber felts are primarily used in electrolyzer stacks as the flow field or diffuser material, particularly on the oxygen (anode) side.  Titanium fiber felts are also widely used in aerospace, civil, medical care, and other industries abroad.

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).
