BMW and Toyota's Next‑Gen Hydrogen Fuel Cell: Compact, 2028‑Ready

BMW 與 Toyota 下一代氫燃料電池：緊湊型、2028 年量產準備

BMW is preparing a third‑generation hydrogen fuel cell (HFC) system for series production in 2028.

BMW 正準備推出第三代氫燃料電池 (HFC) 系統，計畫於 2028 年投入量產。

Prototypes are under test as BMW finalizes manufacturing plans and supply collaboration with Toyota.

同時，目前正在測試原型車，並與 Toyota 確定製造計畫與供應合作細節。

What's New

最新動態

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.

體積縮小 25%：第三代 HFC 單元體積比前一代小約四分之一，其尺寸與許多四缸或六缸引擎相近，使平台整合更容易。

Efficiency‑focused redesign: Updated operating strategy and newly developed drive technology aim to improve overall system efficiency and performance.

效率導向的重新設計：更新操作策略及新開發的驅動技術，旨在提升整體系統效率與性能。

NVH benchmarking: BMW is testing noise, vibration, and harshness and overall output to match or exceed other propulsion options.

NVH 基準測試：BMW 正在測試噪音、振動與粗糙度 (NVH)，評估整體輸出，以達到或超越其他驅動選項。

Production & Collaboration

生產與合作

2028 series production target: Plant Steyr is preparing for full‑scale manufacturing, with prototypes informing tooling and process setup.

2028 年量產目標：Steyr 工廠正為全面製造做準備，原型車則用於調整工具與生產流程。

Division of roles: Toyota will continue to supply the fuel cells, while BMW leads system integration and vehicle packaging.

角色分工：Toyota 將繼續供應燃料電池，BMW 則主導系統整合與車輛封裝設計。

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.

參與設施：主要組件與製造活動分布於 Steyr、Landshut 及慕尼黑。Landshut 持續生產外殼與壓力板，並累積 iX5 Hydrogen 試點車隊的經驗。

System Layout & Validation

系統布局與驗證

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.

緊湊的一體化設計：原型車將氫氣／空氣供應、冷卻系統、電力分配及水管理整合成單一模組，簡化封裝及驗證流程。

Final proofing underway: Prototypes are being used to validate safety and performance and to inform final production tooling.

正在進行最終驗證：原型車正用於安全性與性能驗證，並提供最終量產工具設計的依據。
