Bosch unveiled the FCPM C100, a fuel cell power module designed for urban buses, at the Mobility Move trade fair in Berlin on March 10. The compact unit stands just 40 centimeters tall, allowing rooftop installation typical of European city bus configurations. When paired with renewable hydrogen, the system enables fully CO₂-free electric operation.
Highlights
- New FCPM C100 is purpose-built for 12- to 18-meter city buses with a low-profile design for rooftop mounting.
- Power range of 100 to 300 kW across the full FCPM portfolio covers city buses, intercity coaches, and heavy trucks.
- EU regulation requires a 90% reduction in CO₂ emissions from new city buses by 2030, with all bus types following by 2040.
- Demo vehicle testing of the FCPM C190 intercity variant is planned for the first half of 2026.
FCPM C100 Design and Integration
The C100 is the newest addition to Bosch’s fuel cell portfolio. Its flat, 40-centimeter profile makes it suitable for roof-mounted installation, which is the standard configuration for European city buses. The system includes CAN and diagnostic interfaces for straightforward integration.
The C100 is based on the FCPM C190, a variant designed for intercity buses and coaches. The C190 installs in the vehicle’s rear section, similar to conventional diesel powertrains. Bosch plans to begin testing the C190 in demonstration vehicles during the first half of 2026.
Full Portfolio Spans 100 to 300 Kilowatts
Bosch’s FCPM lineup now covers three power tiers. The C100 targets city buses, the C190 serves intercity and coach applications, and the C300 delivers 300 kilowatts for heavy trucks and long-distance coaches.
“The fuel cell is especially well-suited for buses that travel longer distances every day and rarely have the opportunity to charge en route,” said Jan-Oliver Röhrl, executive vice president of Bosch’s Power Solutions division and chairman of Bosch’s global commercial vehicle activities.
EU Emissions Targets Drive Adoption
An EU regulation mandates that carbon emissions from newly registered city buses must fall 90% below 2019 levels by 2030. Starting in 2040, the requirement extends to all other bus categories. The EU classifies vehicles with fuel cell power modules as zero-emission, positioning them as a compliance pathway for transit operators.
Bosch’s Broader Hydrogen Strategy
Bosch is active across the hydrogen value chain, spanning production, infrastructure, and end-use applications. In 2025, the company launched its Hybrion PEM electrolysis stack for hydrogen production. Bosch also develops hydrogen engine technology with port and direct injection components. At the end of 2025, a Bosch development team received the German Future Prize for its work on mobile fuel cell technology.
