Fuel cell technology has been adopted in a new city bus

by

Toyota Motor Europe (TME) will supply Toyota fuel cell unit (TFCM) for Daimler Buses’s new city bus, the Mercedes-Benz eCitaro Range Extender.

Daimler Buses is part of Daimler Truck AG. The TFCM2-F-60 is a second generation flat unit that produces 60 kW of power and can be easily integrated into the roof of the bus, along with the battery and hydrogen tanks.

An important advantage of Toyota fuel cell technology is that the autonomy of the purely electric bus can be extended to urban traffic to about 400 km for the regular bus and up to 350 km for the modular version of the bus. The combination of the battery and the fuel cell as an extension of autonomy eliminates the need for intermediate charging on the go.

TME engineers will support the overall design of the system and the integration of the unit into the bus to ensure optimal performance, power and lifespan. The efficiency of the heavy-duty unit leads to relatively low hydrogen consumption relative to energy production. With a built-in voltage converter, the TFCM operates in the voltage range of 450 to 700 volts and more efficiently at around 30 kW.

According to its vision for a carbon-free society, the Japanese brand is promoting the application of hydrogen fuel cell technology beyond passenger cars, to include heavy trucks, vans, boats and buses.

To achieve this goal, the firm is partnering with several European carmakers who share the same vision for hydrogen. Concentrating all types of hydrogen applications around hydrogen infrastructure will support the development of ecosystems where hydrogen mobility can be further expanded.

“We are pleased to partner with Daimler Buses and are pleased to see our sales of hydrogen units in Europe continue to expand. “Toyota is committed to achieving carbon neutrality, and we believe that hydrogen is one of the key building blocks of a future carbon-free society,” said Matt Harrison, President and CEO of Toyota Motor Europe.
