The use of hydrogen as an energy source is rising, in applications that transform it into clean electricity through fuel cells with bipolar plate stacks. Key fuel cell applications include Proton Exchange Membrane Fuel Cell (PEMFC), for vehicles, and Solid Oxide Fuel Cell (SOFC) for stationary power generators. Today, Alleima Surface Technology stands as an industry leader in providing coated strip for both PEMFC and SOFC bipolar plates on an industrial scale.

Ensuring the safe distribution of hydrogen within a vehicle is a top priority. Currently, we provide continuous support to various OEMs in efficiently and safely transporting highly pressurized hydrogen from pressure tanks to fuel cells for the next generation of hydrogen vehicles.

Sanergy™ LT

Alleima Surface Technology produces coated strip for PEMFC bipolar plates using a technologically advanced, environmentally friendly vacuum-coating process, applied to long continuous lengths. This eliminates the need to wait for sub-suppliers to coat individual plates. With Sanergy™ LT technology, we deliver PVD-coated coils in continuous lengths up to more than 10,000 meters – all with nanometer-level precision.
