Hydrogen fuel cell bipolar plates can be divided into three types: graphite plates, metal plates, and composite plates.

Today, we mainly introduce the characteristics of metal plates as Hydrogen fuel cells:

1. Good electrical and thermal conductivity;
2. Mechanical shape, good quality and high strength;
3. Good gas barrier;

Metal has good conductivity and heat dissipation, and is most suitable for Hydrogen fuel cell. Moreover, due to its weak corrosion performance, it faces corrosion problems. At the same time, the proton exchange membrane is slightly degraded, and the PH value of the generated water is weakly acidic, which will cause metal bipolar plates. The oxide film of the oxygen evolution electrode thickens and reduces the performance of the battery, so its corrosion resistance can be increased by coating the surface.

However, the characteristic of titanium metal is corrosion resistance, so it is undoubtedly the best choice to use titanium metal with a precious metal coating on the surface as a bipolar plate. Although the cost rises, the service life is also increased along with its effectiveness Good, so titanium has been vigorously promoted in fuel cells in recent years.

The following are some titanium products used for hydrogen fuel cell bipolar plates, please refer to it. (Titanium products with different sizes, shapes and coatings can be customized, supporting proofing)

The concepts related to titanium sintering are as follows:

Titanium powder sintered filter originals are generally microporous filter materials processed from irregular powder of pure titanium or titanium alloy, which can be statically pressed, molded, extruded and sintered. Mainly used in the separation and filtration of petrochemical, liquid medicine manufacturing, medical equipment and other basic industries, as well as ozone generators and fuel cells, hydrogen production.
