Titan in Hydrogen Technology

Titanium plays a crucial role in hydrogen technology, particularly in the manufacture of electrolyzers used for hydrogen production through water electrolysis. Titanium is extremely resistant to corrosion in acidic and alkaline environments that occur during the electrolysis process, especially when water is split into hydrogen and oxygen. This outstanding corrosion resistance ensures a long lifespan and efficient functionality of the bipolar plates, which are an important component of electrolyzer cells.

Another advantage of titanium in hydrogen technology is its sufficient electrical conductivity, which allows the current to flow through the bipolar plates – a critical factor in the electrolysis process where electricity is passed through water to split it into hydrogen and oxygen. In combination with special coatings, the electrical conductivity of titanium can be further enhanced, thereby increasing the overall performance of the electrolyzer.

A significant advantage of titanium is the ability to coat it with catalysts such as platinum, iridium or ruthenium. These catalysts increase the efficiency of hydrogen production by significantly improving the electrochemical properties of the electrode plates and reducing resistance during the electrolysis process. These coatings optimize reaction speed and contribute to a higher hydrogen yield.

Additionally, titanium offers excellent mechanical strength and structural integrity, even under the high-pressure and high-temperature conditions that can occur in modern electrolyzers. These properties ensure that titanium reliably withstands the mechanical stresses during operation without losing its functionality or stability.
