Bosch's Hydrogen Fuel Cell Power Module | ACT Expo 2026

TL;DR

Bosch's C300 fuel cell power module delivers 300kW for Class 8 trucks and doubles as a stationary data center power source.

Key Points

• 1.The C300 is Bosch's second-generation 300kW fuel cell power module. It upgrades from the previous C190 (190kW), uses two horizontal fuel cell stacks with a single power transfer unit and shared controls, and is designed to drop directly into the frame rails where a diesel engine would sit.
• 2.Horizontal stack orientation was key to fitting the larger 300kW output within the same Class A truck envelope. Width constraints drove the design change; the module is slightly longer and taller than the C190 but maintains the same mounting footprint.
• 3.The C300 is being repositioned for stationary data center power amid slower US hydrogen mobility adoption. Bosch is partnering with PowerCell for stationary sales, and existing hydrogen pipelines across the country can supply data centers as a primary, secondary, or backup power source.
• 4.For long-haul trucking, hydrogen fueling takes under 45 minutes versus lengthy EV charging, improving TCO. Hydrogen also eliminates heavy battery weight that reduces payload capacity and revenue for fleet operators, making it best suited for fixed corridors with established hydrogen supply.
• 5.Bosch is collaborating with Kodiak on an autonomous sensor pod for Class A trucks to address driver shortages. The pod replaces side mirrors with radar and cameras, enabling driverless operation without waiting for electric truck infrastructure, targeting the trucking industry's largest cost center.
