Alternative drive technologies using renewable energies

One possibility to use renewable energies is the fuel cell, which after decades of development now fulfills the necessary requirements regarding durability and robustness to be used in many areas.

In order to make these systems economically attractive also outside of promotional measures, among other things the manufacturing and production costs must be massively reduced. Ruhlamat has set itself the task of supporting customers in the industrialization of fuel cell components and developing systems for effective production.

Hydrogen - energy carrier of the future

Innovative solutions are needed to move the industry forward and give even greater support to the topic of new energy on our roads. To this end, we are working together in the field of e-mobility with fuel cell drive (FCEV) in an international team of experts from institutes such as KIT and Tongji University. In addition, we are also represented in the Fuel Cell BW cluster and are working together with other industrial partners in the FCI (Fuel Cell Industrialization) consortium on the development of efficient processes for manufacturing fuel cells.

Our goal is to accelerate research and development in the field of renewable energies and fuel cell systems in Germany and China and thus help shape the future of fuel cells. Our assembly and production facilities for fuel cells, electric drives and electrolysers are delivering initial results.

Fuel cell - production and assembly

Production Fuel Cell ruhlamat

In the production of fuel cells, efficient cycle times and absolute precision are crucial. Our systems cover all process steps from stack assembly to the finished fuel cell system.  The modular, scalable design of the systems allows individual adaptation to the production capacity targeted by the customer.  

The main objective is to reduce the manufacturing costs of fuel cells in order to make the use of these technologies more economical. However, this can only be achieved by scaling effects, which require fully automated plants with correspondingly high capacities. At the moment, this type of production plant is not yet available on the market and the design of the components must also be further optimized with regard to automation-compatible construction.

We want to master these challenges together with our customers. The adaptation of the component design in combination with completely rethought assembly processes is the key to achieving this. We are already working on machine solutions with international teams of product and production specialists from renowned institutes and industrial partners.

In the future, hydrogen electrolysis will play a decisive role in achieving climate targets. For example, surplus energy from wind power plants that cannot be used at present can be used to produce hydrogen by electrolysis. We develop production plants for electrolysers including stack assembly and stack press. We also design individual solutions for prototypes or complete production plants for serial production.

Electric drive (electric motors)

From today's perspective, the drive technologies of the future are BEV (battery electric vehicle) and FCEV (fuel cell electric vehicle). For both fuel cell powered and battery powered vehicles, fast and efficient production of electric motors is essential. State-of-the-art processes such as the Hairpin method are used to automate the individual work steps even further. Here, too, we develop complete production lines as well as individual special solutions.
