BMW and Toyota’s Next‑Gen Hydrogen Fuel Cell: Compact, 2028‑Ready BMW is preparing a third‑generation hydrogen fuel cell (HFC) system for series production in 2028. Prototypes are under test as BMW finalizes manufacturing plans and supply collaboration with Toyota.
What’s New
- 25% smaller package: The third‑gen HFC unit is about a quarter smaller than its predecessor, with a footprint similar to many four‑ and six‑cylinder engines, making platform integration easier.
- Efficiency‑focused redesign: Updated operating strategy and newly developed drive technology aim to improve overall system efficiency and performance.
- NVH benchmarking: BMW is testing noise, vibration, and harshness and overall output to match or exceed other propulsion options.
Production & Collaboration
- 2028 series production target: Plant Steyr is preparing for full‑scale manufacturing, with prototypes informing tooling and process setup.
- Division of roles: Toyota will continue to supply the fuel cells, while BMW leads system integration and vehicle packaging.
- Facilities involved: Key components and manufacturing activities span Steyr, Landshut, and Munich. Landshut continues to build housings and pressure plates, including
experience from the iX5 Hydrogen pilot fleet.
System Layout & Validation
- Compact, all‑in‑one approach: Prototypes integrate hydrogen/air delivery, cooling,
electrical distribution, and water management into a cohesive module to streamline packaging and validation. - Final proofing underway: Prototypes are being used to validate safety and performance and to inform final production tooling.
