PVD Sputtering Equipment & Chemical Pretreatment Systems for Bipolar Plates & Electrolyzers



High Volume Systems for advanced PVD Processing and Chemical Batch Treatment for successful Production of Bipolar Plates for Fuel Cells and Electrolyzers

SINGULUS TECHNOLOGIES successfully entered the expanding hydrogen market with the further development of suitable coating processes as well as the corresponding adaptation of its machine technology. Thanks to the company’s core competence in vacuum coating technology (PVD sputtering) efficient solutions for various applications, such as the production of bipolar plates, can be provided.

SINGULUS TECHNOLOGIES works intensively with partners on the development and optimization of coatings for metallic bipolar plates used in fuel cells and electrolyzers. The modular inline sputtering system GENERIS  PVD from SINGULUS TECHNOLOGIES enables the variable deposition of different layer systems and offers the possibility to sputter bipolar plates in all common sizes with a flexible substrate carrier system. The dynamic inline vacuum PVD sputtering enables high-quality and cost-efficient production.

When addressing the surface treatment demands in hydrogen technology, SINGULUS TECHNOLOGIES excels with the SILEX III BPP batch wet processing system, a reliable and field-tested solution. This system is custom-tailored to meet the specific needs of each customer, ensuring unparalleled reliability and precision in its operations. A key advantage of the SILEX III BPP is its ability to deliver consistently clean substrates regardless of the quality variations in the incoming materials. This consistency guarantees uniform conditions for follow-up processes, thereby enhancing the performance of the final product.

Background Electrolysis 

Several electrolysis processes compete on the market with their respective advantages and disadvantages depending on the field of application: alkaline, PEM or high-temperature electrolysis. The first two processes use steel or titanium bipolar plates stacked together with a membrane and gas-conducting elements. High-temperature electrolysis is based on a ceramic solid membrane. A very promising process for hydrogen production for non-uniform operation, i.e., renewable energy sources, is PEM electrolysis (PEM: Proton Exchange Membrane). Due to the expected market for electrolyzers, inline cathode sputtering plants with their large throughput are ideally suited here for PEM as well as for alkaline electrolysis.

Different coating systems can be deposited with the modular GENERIS PVD inline coating system. With its flexible substrate carrier system, the GENERIS PVD offers the possibility of coating bipolar plates in all common sizes.
