About us
Graebener® is a 100 years old machine building company with locations in Germany and the USA. For more than 20 years, it has been one of the first companies to focus on the R&D of manufacturing processes and machines for fuel cell and electrolyzer components.The company has dedicated itself to setting the quality standard for manufacturing technologies by developing innovative processes and machines that help to manufacture components of fuel cells and electrolyzers, such as the metallic bipolar plate, that that are tailor-made, integrable, scalable and thus economically efficient.
For this purpose, Graebener® accompanies all strategically important steps towards the optimally designed production line: Starting from engineering with a view to plate design and line concept via prototyping and small series production in the in-house production laboratory up to the customized production machine or line.

Products & Services
Engineering: Plate Design Analysis & Process DevelopmentWe analyze your design regarding manufacturability and develop modifications. Further, we implement your idea as a CAD model for you.
For your own production, we analyze all production steps and develop a scalable line concept for your infrastructure.
Production Laboratory: Prototyping & Small Series
In our production laboratory we verify the manufacturability of your bipolar plate design.
With our continuously optimized and patented technology we also produce smallest lot sizes and small series of your plate design.
Production Lines: Individual Machines & Lines
We realize your individual single machines (hydroforming, cutting, welding, straightening) including all tools.
For more complex projects we develop tailor-made and scalable lines for series production – from coil to finished bipolar plate for fuel cells and electrolyzers.
In addition, we support you with our stack press in the technical testing of your stacks.
Graebener Production Line for Bipolar Plates of Fuel Cells and Electrolyzers
We realize your individual single machines for hydroforming, cutting, welding and straightening including all tools.
For larger and more complex projects we develop tailor-made and scalable lines for series production – from the coil to the finished bipolar plate for fuel cells and electrolyzers.
In addition, we support you with our stack press in the technical testing of your stacks.
Graebener Stack Press for Stack Testing
Graebener Stack Press Supports the Testing of Stacks for Fuel Cells and Electrolyzers:
Our stack presses support the technical testing of fuel cell and electrolysis stacks at the end of their production processes.
The pre-assembled stack, which consists of a large number of plates, is first moved into the machine and then compressed to a defined height until a certain pressure is reached within the stack. This pressure must then be maintained unchanged for several hours. At this time, the stack is subjected to all the necessary technical tests carried out by the customer and with the help of further procedures. These are necessary to confirm its full operability. As soon as the tests are completed, the stack is finally assembled with tie rods or tension straps and the finished stack is removed.
Graebener Production Laboratory for Prototyping and Small Series Production
In our production laboratory, we are able to verify the manufacturability of your bipolar plate design using a selected area as test geometry – this way you obtain initial results quickly and cost-effectively. This also applies to the design optimizations we work out.
With the continuously optimized and patented Graebener® technology used in the laboratory, we are able to produce smallest lot sizes and small series of your plate design – and later transfer the production parameters one-to-one to your own Graebener® production line.
Graebener Engineering for Our Services Plate Design Analysis and Process Development
We analyze your design regarding manufacturability and work with you to develop modifications so that your plate can be successfully manufactured – also with regard to the necessary features for an economic series production. You do not have a design yet?
We would be pleased to implement your idea as a CAD model for you.
For your own production, we analyze all production steps – from the coil to the finished bipolar plate – and develop a scalable and future-proof line concept based on the analysis and in consideration of your infrastructure.
