Factors Determining Cost of Titanium Felt

Consider the following factors to determine the price of titanium felt:

  • The purity of titanium

Filson provides standard titanium material with different purity(TA1/TA2/TA3/TA4) to fabricate titanium felt. The higher the titanium purity, the higher the price is. You can choose proper purity according to your applications.

  • Thickness of titanium felt

The common thickness of titanium felt is ranging from 0.25 to 1mm. Different thickness are produced with different quantity of fibers.

  • The porosity of titanium felt

As a new energy material, porosity is essential to the characteristics of titanium felt, especially electrical conductivity.

With the porosity design of 53% to 90%, Filson titanium felt can increase or decrease its surface area to meet your electrical conductivity needs.

Certainly, the higher the porosity, the more you will pay.

  • Whether to be platinized

In order to avoid the oxidation and operate better under high pressure environment, Filson offers you platinized titanium felt.

Whether to be platinized depends on your design. If you need platinized titanium felt, the price will be higher than common titanium felt.

  • The electrical conductivity of titanium felt can be designed to 2.38 x 106 S/m.
How Long Can Titanium Felt Last?

Being able to be cleaned through chemical cleaning, ultrasonic cleaning or other cleaning methods, titanium felt is reusable. And Filson titanium felt has longer lifespan to be used for 2 years.

Titanium Felt Fabrication Process

Filson Titanium Felt Packing

We fabricate titanium felt through the following procedures below:

  • Place the titanium felt in a vacuum sintering furnace and heat up to between 400℃ and 500℃. Maintain these temperature for 1 to 3 hours.
  • Conduct low-temperature sintering. Then obtain a low temperature titanium felt after natural cooling.
  • Compress the low-temperature titanium felt through the hydralic press to achieve high porosity ranging from 60% to 90%.
  • Return the compressed titanium felt into a vacuum furnace and heat between 800℃ and 950℃. Maintain the temperature for 30 to 45 minutes.
  • Conduct high-temperature sintering. Allow it to cool naturally to achieve quality titanium felt.
When Should I Choose Platinized Titanium Fiber Felt?

The main function of platinum coating is mainly to shorten oxidation and maintain the electrical conductivity of titanium felt.

When you use titanium felt in a high pressure environment than ambient pressure usually between 1 bar and 3 bars, there will be oxide coating comes into being on the surface of titanium felt. As a result, the interfacial resistance in the cell will be increased, and the electrical conductivity conductivity will be decreased.

At this time, platinized titanium fiber felt had better be chosen to prevent oxidation and stabilize the electrochemical performance of titanium felt.

What is Electrical Conductivity of Titanium Felt

Titanium Felt vs Titanium mesh

Being regarded as a new energy material, titanium is popular in electrode and power industry in recent years. Filson titanium felt is fabricated with pure titanium, and its electrical conductivity at 20℃ can reach 2.38 x 106 S/m.

Titanium felt is ideally applied in electrolyzer stacks as the flow field or diffuser material, especially on the oxygen anode side. Besides, it can also be used in PEM water electrolysis hydrogen industry, PEMFC fuel cells industry, etc.

If you choose platinized titanium fiber felt, the platinum coating can also conduct electricity  and maintain stable under the oxygen and high pressure environment. Therefore, the electrical conductivity of titanium felt will be stabilized.
