Fuel cell electric drive

The fuel cell is a key technology for emission-free mobility, particularly where long ranges and heavy payloads are required. In heavy-duty transport, the fuel cell electric drive represents a powerful and sustainable solution to align demanding transportation tasks with global climate targets.

Bosch focuses on industrializing this future technology. Our comprehensive portfolio ranges from the core element – the fuel cell stack – to all essential system components. With deep system understanding and modular approaches, we support manufacturers in efficiently integrating the technology into vehicle fleets.

Operating principle of a fuel-cell electric drive system

The fuel cell electric drives for zero local emissions and longer range

The fuel cell electric drive is an economical and attractive technology for locally emission-free driving. A fuel cell vehicle is electrically powered, with the electrical energy generated directly in the fuel cell from the hydrogen fuel source. The electric drive converts this energy into motion or temporarily stores it in the traction battery.

Bosch pursues a holistic approach, offering fuel cell electric solutions for all vehicle segments. The comprehensive portfolio ranges from electric drive components to innovative fuel cell technology. Depending on requirements, flexible solutions are available for the fuel cell system: from the stack and individual components in the submodules to a perfectly coordinated overall system for the sustainable mobility of tomorrow.
