Hydrogen: Electrolyzers and Fuel Cell


Products for the hydrogen and fuell cell industry by TOX Pressotechnik

TOX® in use for the production and use of hydrogen

In the recent past, the focus has been on hydrogen, and green hydrogen in particular, as one of the hopes of the energy transition. Both for clean and climate-neutral energy generation and for meeting the increasingly stringent CO2 targets. The national political course has already been set and the international community is joining forces in the form of research, project and trade cooperations.

Cost-efficient production is essential in order to drive the ramp-up of the hydrogen economy and scale up the number of electrolysers and fuel cell stacks. This requires a significant increase in production capacity: from small series with numerous manual process steps to automated series production. TOX® supports you with comprehensive technological expertise, high-performance joining modules and complete presses to ensure consistently high quality even with large-volume production.

The methods of hydrogen production (electrolysers) and hydrogen utilization (fuel cell stacks) already in commercial use, AE / AFC (alkaline) and PEM / PEMFC (polymer electrolyte membrane), are being expanded by new technologies such as SOEC / SOFC (solid oxide / high temperature). And the requirements in terms of current density, operating temperature, pressure in the cell and the size of the stacks are also constantly increasing.

Further fields of application:

  • Connecting clamping straps for hydrogen pressure vessels or fuel cell stacks using TOX® Clinching

  • Tight press-fitting / assembly of valves for hydrogen pressure vessels using the TOX® ElectricDrive Core

How TOX® makes your production of electrolytic cells, electrolyzers and fuel cell stacks more efficient

Inspection of upstream production parts, feeding of components (pre-assembly).

Pressing and holding the stacks with forces of up to 1000 kN over a defined period of time.

Maximum worker safety during manual bolting of the stacks.

  • Permanent monitoring and documentation of the process - pre-stroke, pressing process, return stroke.

Strokes even of more than 1000 mm.
