Technology consulting on fuel cells, hydrogen and electrolysis:
EMCEL develops feasibility studies, cost analyses and business models for your market environment. Our experience ranges from electrolysis or power-to-go systems and industrial hydrogen use via energy storage systems on the basis of hydrogen, right up to hydrogen filling stations.

Publications & Documentations: EMCEL creates specialist articles and brochures, technical guidelines and documentation materials for you.


Product- & System development:
We support your development projects with regard to approval, standards, certification and safety. Furthermore, we perform development work with the layout and optimisation of your systems or components.

Hydrogen quality measurement:
We measure the purity of your hydrogen source as a service upon request or provide you with measuring equipment.


Service & Maintenance:
We service your battery and fuel cell buses, as well as your hydrogen and fuel systems. We have built up our range of service and maintenance activities into a modular system, which we configure individually for your requirements.

We develop your ideas together with you. We look forward to meeting you.
