ATMOcoat specialises in functional precious metal coatings. Using an innovative, patented plasma-based “metal airbrush”process, the company primarily applies platinum, gold, iridium and palladium coatings for PEM electrolyser components and hydrogen separation membranes. The atmospheric process avoids the complications of vaccum and is highly metal-efficient. The company was founded in 2019 and has both R&D and production facilities in Berlin.
