Cover Story: The transition toward zero-emission public transport depends on smarter, more efficient fuel cell electric buses. This study explores how electric motor size, fuel cell power, and hybridization level shape both performance and energy use in urban operation. Using ADVISOR simulations on the CBD driving cycle, the authors show that fuel cell power primarily governs acceleration, while the electric motor becomes critical for gradeability once a key power threshold is exceeded. Increasing the hybridization ratio toward fuel-cell-dominant setups reduces dynamic performance and raises total energy consumption, revealing a delicate balance between efficiency, sustainability, and charge-sustaining capability. The work offers clear design guidelines for next-generation powertrains in urban transit.
