Hydrogen and Fuel Cell Systems

© AdobeStock_parradee

The integration of fuel cell systems in vehicles is a great challenge, especially in commercial application fields such as trucks, public service buses, coaches, as well as machines used in agriculture and construction.

Fraunhofer IVI supports their clients and partners from the abovementioned sectors during the essential steps in the implementation of hybrid propulsion solutions involving fuel cell systems.


High-performance design tools allow the ideal dimensioning of entire powertrains, fuel cell systems and the vehicles' internal energy storage units.


Operating strategies

In order to monitor and control their efficiency, lifespan and costs, expensive components such as traction batteries and fuel cell systems require optimal operating conditions.

At Fraunhofer IVI, diverse operating strategies are developed for a wide range of applications with the aim of ensuring the components' optimal operation in the target application.


Integration and control

At the institute, powertrains of test vehicles and vehicle prototypes are set up, initialized and tested. The service offer extends as far as the functional integration of components and systems in the target vehicles.



Hydrogen systems often require higher safety levels in terms of the respective machine's functional and operational safety. Therefore, the institute also supports their partners and clients during the safety assessment process and in deriving and implementing safety measures.
