New Technologies

 

New technologies have been the daily business of Gräbener Maschinentechnik for many years, especially as service provider for the manufacturing of components for and the assembly of fuel cells.

 

We have pushed boundaries of hydrostatic deep-drawing so far that former utopias have become reality. Gräbener Maschinentechnik not only develops a large variety of separator plates but also is able to ensure their economic series production. For example as core elements of fuel cells for power generation, as electrolyser for the extraction of hydrogen or as high-performance heat exchangers for the reformation of inflammable gases.

 

We are certain: These technologies are the right path to the future. Yours as well as ours.

 

PowerBoxx®

 
The "PowerBox"®, a development within the competence network fuel cell and hydrogen in North Rhine-Westphalia, has been developed especially for the production of metallic separator plates. It was put into service at the beginning of 2006.

 

The PowerBoxx® has a closing force of 65,000 kN and can form separator plates up to a total surface of 400 cm² using the Opens internal link in current windowhydroforming process. Various materials such as 1.4301 or even titanium are feasible.

 


Metallic separator plates

 

In the sector of "new technologies", Gräbener Maschinentechnik is among the early developers and manufacturers of metallic separator plate units for NT-PEM, HT-PEM, DMFC and SOFC fuel cells, microstructure plates and plates for high-performance heat exchangers, made from various metallic materials.

 

Gräbener Maschinentechnik, as part of the fuel cell industry in Germany and as a member of VDMA consortium for fuel cells ("Arbeitsgemeinschaft Brennstoffzellen"), puts much effort into the research & development of how to provide future energy supply with competitive and optimized components and units.

 

Gräbener Maschinentechnik profits exceedingly from the process know-how of the conventional divisions and is able to use this knowledge in combination with its vast technology competence for the establishment of a production-oriented industry perspective regarding the manufacturing of components for the fuel cell industry.
