Press Release

World premiere at f-cell 2022 in Stuttgart:

German Fuel Cell Cooperation presents highly productive production line for metallic bipolar plates

For the first time, the German Fuel Cell Cooperation (GFC) will present a highly productive, interface-tuned complete line for the production of metallic bipolar plates at the f-cell 2022. The event will take place in Stuttgart from 4 to 5 October 2022 and the GFC will exhibit at booth 2D17 in hall 2.

By combining their respective competencies, the three companies VON ARDENNE (Dresden), Weil Technology (Müllheim) and ZELTWANGER (Tübingen), as partners in the GFC, offer manufacturers of fuel cell systems and electrolyzers fully comprehensive know-how for the efficient production of metallic bipolar plates.

The concept of a fully coordinated production line plays a pioneering role in the market. And, with an annual production capacity of several million bipolar plates, it serves the current needs of the industry.

The long-standing expertise of the three mechanical engineering companies covers all process steps. And the joint development and careful coordination of the line concept enables smooth transitions at the interfaces of the individual production steps. To this end, the line processes pre-stamped half-plates made of stainless steel or titanium. In a first step, these are welded into bipolar plates, then leak-tested and given a PVD coating to functionalize the surface.

With their extensive joint knowledge of the complex value chain and high degree of specialization in the sub-processes, the three GFC companies develop a customized production line together with their customers. These specification-compliant production lines optimally integrate the various customer-specific approaches.

VON ARDENNE contributes its expertise in the construction of vacuum coating systems used to functionalize surfaces of metal strip (pre-coating) or bipolar plates (post-coating). Weil Technology is an experienced supplier of equipment in the field of laser cutting and laser welding of metallic bipolar plates. ZELTWANGER provides the equipment for automated assembly and testing processes as well as leak testing into the production chain.

VON ARDENNE develops and manufactures systems for the industrial vacuum coating of materials, such as glass, wafers, metal strips or polymer films. Depending on the application, these coatings are one nanometer to a few micrometers thin and give the materials new functional properties. Our customers use these materials to produce high quality products, such as solar cells and solar modules, architectural glass and vehicle glazing, fuel cells, lithium ion batteries or microelectronic components for sensor systems and optics. Systems and components provided by VON ARDENNE make an important contribution to protecting our environment. They are crucial when producing products that help to consume less energy or that generate energy from renewable resources.

With more than 60 years of experience in electron beam technology and over 45 years of experience in magnetron sputtering, VON ARDENNE is a pioneer and worldwide leading supplier of systems and technologies in PVD thin-film and vacuum process technology. We offer our customers technologically mature vacuum coating systems, comprehensive expertise and global service. The key components are developed and manufactured in-house at VON ARDENNE.


As a machine builder and solution provider, Weil Technology supports the realization of new production processes in sheet metal processing as well as the optimization, automation and sustainability of existing ones.

The company's core competence is machines for sheet metal processing by laser welding and cutting. Weil Technology can look back on more than 30 years of experience in this field. At the company's headquarters in Müllheim in southern Baden, around 220 employees develop and manufacture customer-specific concepts and systems.


The companies of the ZELTWANGER Group are among the technology and innovation leaders in the development and manufacture of modern systems for automation, leak testing, laser applications and thermal management.

For the e-mobility industry, ZELTWANGER offers diverse solutions along the entire value chain for the production and quality assurance of battery systems, fuel cells and electric motors.

The modularly designed devices and systems for leak and function testing are easily expandable by using plug-and-play measurement modules, which is unique on the market. In addition, ZELTWANGER develops and implements high-end automation systems such as stacking systems for the fuel cell industry.
