The technology in the new eCitaro fuel cell is the perfect solution for very long ranges. The Mercedes-Benz city bus runs entirely on power from two energy sources. Its latest-generation high-performance batteries make it powerful electric bus indeed. And its hydrogen fuel cell safeguards the energy supply on the road – with no need for interim charging.

The new eCitaro fuel cell is a veritable miracle of endurance. On its long routes through the city, it uses the latest generation of high-performance batteries: NMC 3. Their high energy density pays off: NMC-3 batteries have around 50 percent more capacity than the previous generation at the same weight. A fuel cell is used in the eCitaro fuel cell to charge the batteries while the vehicle is in operation. The heavy-duty variant of the major assembly generates a maximum output of 60 kW. It runs highly efficiently in the eCitaro fuel cell, around 20 kW at its best point. This results in a comparatively low hydrogen consumption in relation to the power it generates. And this results in a significantly increased range for you to cover even demanding routes.

The modular system of the eCitaro fuel cell enables different battery and hydrogen tank combinations – and thus the right configuration for any requirement. The solo bus is available with five hydrogen tanks boasting a total H2 capacity of 25 kilogrammes as well as with three battery packs with a total energy content of 294 kWh. Mercedes-Benz can equip the articulated bus with a choice of six or seven hydrogen tanks providing a total capacity of 30 or 35 kilogrammes, as well as three or four battery packs with a maximum energy content of 392 kWh. The hydrogen system is designed for a pressure of 350 bar. The fuel cell module in the solo bus is installed on the roof just behind the front axle. In the articulated bus it is installed at the front of the rear section's roof. The carbon fibre reinforced Type 4 hydrogen tanks, each with a capacity of five kilogrammes, are also installed on the roof. They are lightweight, highly durable and certified as per ECE R 134.
