The fuel cell and the electrolyzer are key technologies for an ecologically and economically sensible energy generation in future. At Graebener® Bipolar Plate Technologies, we focus on the development, optimization and realization of the manufacturing technologies for the bipolar plate, the core of fuel cells and electrolyzers. As an elementary component of both the fuel cell and the electrolyzer stacks it helps, on the one hand, to generate clean electricity from hydrogen and air, and on the other hand, to convert electricity (e.g. from renewable energies) into hydrogen.

This makes the fuel cell and the electrolyzer interesting not only for future mobility, logistics or the generation of electricity and heat for buildings, but also for numerous branches of industry, such as the steel, fertilizer and gas industries, which will depend on the production of large quantities of green hydrogen in the future.

The bipolar plate is thus important for all applications of energy generation where environmental aspects, energy efficiency and sustainability are relevant.


Our work: Sustainable success from the very beginning.

Metalworking, mechanical engineering, medium-sized business: three characteristics that have been shaping our work since 1921. As a fourth generation family-run company, we develop and manufacture proven solutions for metal forming technology worldwide and across all industries. We are known above all for our precision and attention to detail:

Whoever banks on Graebener® relies on a solution that has been thought out down to the smallest detail. It is not for nothing that today we stand for machines with quality and performance that are convincing in the long term – because we know that what we create must also work for our customers in the future.

Trust in the future?
With security in the medium-sized business.

Markets are subject to change over time. Social, economic and ecological changes have a direct impact on technologies – and thus on our work. As a medium-sized family business, it is therefore in our nature to evaluate thoroughly which technologies are – and will be – important. Because we see it as our duty to guide our company, our employees and last not least our customers safely into the future.

With regard to the stability and sustainability of our customer relationships, it is important to us to maintain a balance between proven solutions, process reliability, innovation and progress. In other words, to consider all the details that characterize sustainable quality.

It is not without reason that we are one of the first companies to have been involved in research and development of production processes and machines for bipolar plates of fuel cells and electrolyzers for 20 years. We believe that the future belongs to hydrogen. And with this investment we are sending a strong signal for the progress that will shape energy production.

With Graebener® Bipolar Plate Technologies we want to make our idea of the future tangible for the present. Not only do we want to create leading and lasting quality for our customers in the spirit of our company‘s history, we also strive to develop solutions that already provide today what the world needs tomorrow.

Project BREEZE! Graebener®proves marketability

Graebener® inside: With the successful completion of the project BREEZE! we proved the marketability of our technology already in 2014. Together with further project partners we realized a 30 kw Range Extender for a Fiat 500.

Within the scope of the project we supplied the metal bipolar plates as proof of concept of our patented manufacturing technology and also contributed to the project with our many years of experience in the area of further value-added chain steps. Today, we have vast experience along the entire value-added chain, from the coil up to the functional fuel cell system.
