laser welding of bipolar plates

Production of bipolar plates

Whether for hydrogen-based electric vehicles, in the stationary operation of fuel cells or in electrolyzers – we support your hydrogen application with the production of project-specific bipolar plates.


When it comes to the production of bipolar plates for PEM and SOFC fuel cells we offer you our extensive services. We produce your samples in small quantities, prototypes, realize pre-series up to large scale series production of several million bipolar plates per year or offer you automated manufacturing concepts for your inhouse production.

Development, construction and manufacturing of fixtures take place in ideal coordination with the machine concept in our factory
