Series-H: Fuel Cell Electric - Electrification Simplified™

Why fuel cell buses?

• Zero emissions: Hydrogen is the sole fuel source, thus water is the sole exhaust
• Quiet and smooth: All electric drive provides quiet operation
• All electric accessories: Electric air conditioning, power steering, air compressor and cooling systems mean higher reliability and efficiency
• Lightweight, nano-phosphate lithium ion battery technology provides the full benefit of hybrid electric operation
• Production qualified systems and components: Reliable, proven commercialized technology
• Designed with the maintainer in mind: Easy access to maintenance and inspection points
• Support: Established support network for bus, propulsion and fuel cell system
• Buy America compliant
   

How does the system work?

Power is blended from the high voltage batteries and hydrogen fuel cell engine through power electronics to provide propulsion at the wheels and to energize electrified accessories. Regenerative braking is utilized to capture kinetic energy during braking and store it in the high voltage batteries. Additionally, the bus is capable of low power, short duration driving solely on the battery when the high voltage batteries have sufficient charge. This feature allows the bus to be moved at the depot without having to start the fuel cell engine.
