Do you know what are the materials for pem fuel cell electrodes? Today we introduce an electrode of good quality that is used by many people for hydrogen production in fuel cells. It is a titanium porous material, which is coated with precious metals on the surface and then used as an electrode.

What is the base material of Pem fuel cell electrodes?

The base material of the Pem fuel cell electrodes introduced today is titanium, called titanium porous or titanium foam. Titanium sintering is a hollow filter tube made of titanium metal powder by powder metallurgy without high-temperature sintering. It is widely used It is used for liquid-solid separation in food, beverage, pharmaceutical, chemical and other industries. It is especially suitable for decarburization and filtration, hydrogen production, and fuel cell electrodes in large infusion and injection production lines in the pharmaceutical industry.

Titanium porous technical parameters are as follows:

What precious metal coatings can be applied to the surface of Pem fuel cell electrodes？

There are three main types of precious metal coatings, namely ruthenium-iridium coating, Ir-Ta coating and platinum coating，If you are not sure which coating to use, or want to know the difference between these two coatings, please feel free to contact us.
