In the year 1999, Christian Machens developed the world's first fuel cell boat, the Hydra, and thereby laid the foundation for innovations that will extend far into the future. Now, 25 years later, he is once again setting standards in the technology landscape – this time with a world first that has the potential to fundamentally change the safety analysis of systems.

Extremely high demands are placed on tools for punching, stamping and forming sheet metals. In some cases, accuracies of between 1 µm and 2 µm are required during manufacturing. The level of challenge increases drastically the larger the tool and the thinner the sheet. The stamping plates for the sheet-metal parts in fuel cell bipolar plates are a prime example. Bipolar plates are thin structures made from welded sheet-metal half shells that enclose the filigree flow fields. They are built up one after another in many layers, with the membrane electrode assemblies sandwiched in between, to produce the final stack.

The company HPS Home Power Solutions has unveiled a new generation of its seasonal energy storage system. The Picea 2 now uses lithium batteries, which makes installation in the home easier due to the lower weight. With twice the power, the appliance is also equipped for e-mobility and heat pumps.

Low weight and volume, good cold-start capability and relatively inexpensive series production are all benefits associated with metal bipolar plates. These key elements in fuel cell stacks are responsible for handling the essential tasks of supplying media, creating an electrical connection and cooling. Their ability to perform these well depends on factors such as the cleanliness of both the material and the joined plate. Ecoclean has trialed a variety of processes to find the most effective and economical method of cleaning.
