In a proton exchange membrane fuel cell, the main function of the gas diffusion layer is to support the catalyst and provide a channel for the gas participating in the reaction and the water generated. It is one of the key components of the membrane electrode.

The porous titanium plate has a good and uniform large number of pores, the porosity can be controlled by adjusting the diameter of the powder, and it is made of sintering, high temperature resistance and corrosion resistance.

Product Parameters

Process: Powder sintering
Fine filter: 1 m 65 m
Material: Pure titanium
Operating Temperature: 0 300
Thickness: 0.8mm 2.8mm

Features
1. Corrosion resistance
It exists between the bipolar plate and the catalyst layer. During the electrochemical reaction, the high current density is 2A/cm2, which has high electrical corrosion resistance and must have corrosion resistance;
2. Porous air permeability
Serve as a medium for hydrogen/oxygen or methanol/air to diffuse to the catalyst layer, and must be a porous and breathable material;
3. High conductivity
To act as a current conductor, it must be a highly conductive material;
4. High thermal conductivity
The reaction is an exothermic reaction, and overheating will cause damage to the proton exchange membrane. The gas diffusion layer must be a high thermal conductivity material to conduct heat away to avoid damage to the proton exchange membrane;
5. Good permeability
Fuel cell reaction to generate water will cause performance degradation, so the gas diffusion layer must be able to export water and have high hydrophobicity;

Due to its characteristics, porous titanium plates can also be used in the following industries:
(1) Manufacture of sweating material. That is, the pores of ordinary powder metallurgy materials are impregnated with low-melting point substances, and they work at high temperatures
At this time, the impregnation melts and seeps out, making the material "sweat" to dissipate heat. In this way, ordinary materials can be used to replace expensive heat-resistant alloys, and the service temperature of heat-resistant parts can be further increased.
(2) Manufacture filter material. Used to filter gas, filtrate, and poison, etc.
(3) Impregnated with the anti-friction agent to manufacture oil-containing and oil-free lubricated bearings; impregnated with spices to manufacture fragrance-containing handicrafts, etc.
(4) Manufacture materials such as vibration reduction, noise reduction, and heat insulation.

0A grade sponge titanium is the basic link of titanium industry, it is the raw material of titanium material, titanium powder and other titanium components. Generally, it is light gray particles with clean surface.
0A grade titanium sponge (the spongy metal titanium) produced by metal thermal reduction method generally has a purity % (mass) of 99.1 to 99.7. The total impurity element % (mass) is 0.3-0.9, the impurity element oxygen % (mass) is 0.06-0.20, the hardness (HB) is 100-157.
Product grade
It is divided into seven grades according to the purity.
Production Process
Titanium sponge is actually the same substance as titanium, but in a different form. In the smelting process of titanium, the product (titanium) obtained through the process of magnesium reduction-distillation of titanium tetrachloride looks like a sponge, hence the name sponge titanium. Their chemical formulas are represented by Ti.

Titanium magnesium reduction method to produce sponge titanium is to reduce titanium tetrachloride to titanium metal titanium with magnesium at high temperature. The reaction process involves multiple systems such as TiC14-Mg-Ti-MgC12-TiC13-TiC12, which is a complex physical process chemical process. The formula is as follows:
TiC14+2Mg=Ti+2MgC12
In order to obtain high-quality sponge titanium, Mg and MgCl2 must be separated.
Application
Sponge titanium is the raw material for the production of all titanium products, whether it is titanium plates, titanium rods, titanium processed parts, and sintered porous titanium filter elements used in the filtration and separation industry, cannot do without sponge titanium.
