Gräbener Maschinentechnik GmbH & Co. KG products

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.

We have developed our patented Graebener® hydroforming press especially for the economic production of metallic bipolar plates and have made it ready for series production. With our sandwich tool, several plates can effortlessly be produced simultaneously per stroke, e.g. the cathode and anode side.
