Production Lines for the Serial Production of Bipolar Plates

  • Scalable production of bipolar plates: from coil to welded bipolar plate
  • Systems for forming, separating, ultrasonic cleaning, cutting, welding, straightening and leak testing as well as handling and automation
  • Modular design guarantees a cost-efficient expansion
  • Determination of all necessary process parameters in our Graebener application laboratory  for a fast start-up of your production lines on site

Production lines for the serial production of bipolar plates

  • Thanks to our many years of experience in mechanical engineering, we are able to develop line concepts that can grow with time.
  • With a view to your increasing quantities or changing component geometries, we develop production lines for the serial production of bipolar plates that can be scaled precisely and sustainably.
  • The modular design of our lines guarantees a cost-efficient expansion of your production line. From the very start, our concept accompanies you safely into the future.
  • We determine all necessary process parameters in advance in our Graebener application laboratory and thus realize a fast start-up of your production lines on site.

Single system to scalable production line

  • We know that there is no such thing as “the one’’ system  because technologies and processes change with market requirements.
  • At Graebener Bipolar Plate Technologies, we endeavor to respond as flexible as possible to present and future requirements of our customers.
  • Regardless of whether you are looking at a single system tailored to your objectives, a complete production line or an extension of an existing line.
  • In all these cases we are your flexible performance partner and realize your individual production line from coil to welded bipolar plate in close cooperation with you.


As a Strong Performance Partner for the Development of your Bipolar Plate Production, we offer you the following advantages in close, constructive cooperation

  • Analysis, modeling and optimization of your bipolar plate design
  • Tool engineering
  • Prototyping as well as production of smallest lot sizes and small series in the Graebener® application laboratory
  • Analysis of the production steps from coil to welded bipolar plate
  • Determination of requirements of individual production systems and necessary handling and automation systems
