KAMAZ has presented the KAMAZ-6290 hydrogen fuel cell bus at the COMTRANS-2021 international exhibition in Moscow.

Bus chassis and body were assembled at NEFAZ, a KAMAZ Group subsidiary in Bashkiria. The roof equipment was installed in the research and technology center of KAMAZ.

The body is made of high-strength steel and plastic, supporting the required durability and safety in emergencies. The total weight of the KAMAZ-6282 hydrogen fuel cell bus is 19 tonnes and its overall dimensions are 12.4 х 2.55 х 3.4 m.

The bus is powered by hydrogen fuel cells and is fitted with six cylinders for compressed hydrogen storage. The cylinders are roof-mounted for safety purposes. Hydrogen flows skyward in case of a leak and does not get into the compartment. Furthermore, unlike the electric bus with the endurance of 70 km after complete battery recharge, the hydrogen fuel cell bus can travel up to 250 km, which makes it applicable even for interurban traffic.

Rostec is the largest shareholder in KAMAZ.

The hydrogen fuel cell system delivers at least 45 kW, which powers the ZF electric portal axle. The bus is equipped with the modern high-performance pneumatic braking system with EBS, ABS, ASR, and EPB, slope stop function, motion interlocking function for open doors, and a monitoring sensor for wear and tear of brake pads.

Braking by traction electric motor with the regeneration system is also provided. Maximum speed is 80 km/h. Total passenger capacity is 80, with 33 seats. Like the electric bus, the new eco-transport is adapted to operation at the ambient temperature from -40 ° to +40 °С.
