Singulus Technologies AG
SINGULUS TECHNOLOGIES is a leading supplier of advanced machinery and systems for high-precision thin-film coating and surface treatment processes. With a global footprint, our technologies are applied across a range of industries—including photovoltaics, semiconductors, medical technology, packaging, glass & automotive, and the rapidly growing battery and hydrogen sectors.
Our core expertise spans a wide range of deposition and surface engineering technologies, including: PVD sputtering, PECVD, Thermal evaporation (e.g., Close-Space Sublimation, CSS), Surface activation and pre-treatment, Wet-chemical and thermal process integration.
In the hydrogen sector, bipolar plates (BPPs) represent a significant portion of the weight and account for a large share of the manufacturing cost of PEM fuel cell and electrolyzer stacks. To enable cost-efficient, high-volume production, advanced coating solutions are essential. These functional coatings directly influence corrosion resistance and interfacial contact resistance—key factors for ensuring long-term durability, high electrical efficiency, and system reliability.
