Technology

Two key elements of a CO2-free energy economy based on hydrogen technology are fuel cells and electrolysers. Electrolysers produce hydrogen, which can then be used directly in industrial processes, transported and stored. The conversion of hydrogen into derivatives such as ammonia, methanol, etc. opens up a wide range of applications in the chemical industry and the energy sector.
Fuel cells are used to convert hydrogen and oxygen into water, generating electricity in the process. Fuel build the centerpiece of a CO2-free future in the transportation sector with cars, trucks, buses, trains, planes, boats and ships or for local and stationary power generation.
Bipolar plates are an essential component of fuel cells and electrolyzers and are typically made from thin sheets of sheet steel or titanium.Suitable coatings on these bipolar plates can optimize their conductivity and corrosion behaviour and thus their service life in demanding applications.
The properties of other electrolyser components such as PTL (porous transport layer), GDL (gas diffusion layer) and interconnects can also be significantly improved through customized coatings.
