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.

Design

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.

 

Safety

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.

Projects

 

Applications for hydrogen-based electromobility

Hy.CoMM: Clean Hydrogen Construction and Mining Machines

Transitioning from diesel to fuel cell powered vehicles can be a promising solution in the challenge of reducing on-site emissions at mines and construction sites. The aim of the application-oriented research project Hy.CoMM is to find applications for hydrogen-based electromobility in these areas.

 

Low-emission drive systems for mobile work machines

H2ROAM: Hydrogen for Robust Off-Road Application Modules

Decarbonizing heavy industrial machinery is challenging because the extreme conditions under which it operates make electrification alone insufficient. Hydrogen-powered powertrains, however, offer a promising approach. The European H2ROAM project, launched in 2026, aims to demonstrate how viable this path is.

 

Hybrid energy system for e-VTOL aircraft

HYPESS: Hybrid Power Packs with Innovative Energy Management and Energy Security System for UAM Applications

The project's goal is to develop a high-performance, reliable, and completely emission-free power supply system that overcomes the current limitations of battery-powered aircraft and paves the way for safe and sustainable aviation in the future.
