Proton Motor Fuel Cell and Skoda Electric has presented a preview of the world’s first fuel cell triple hybrid linen bus, which will go into operation this summer in Prague.
The project is a cooperation between Skoda Electric, the systems integrator and electrical components, the UJV Nuclear Research Institute, R&D and project coordination and Proton Motor, which produced and delivered the fuel cell triple hybrid propulsion system.
The triple hybrid system is a world first combination of a fuel cell, batteries and ultra capacitors, allowing for the saving and further use of useful braking energy. The system is reported as saving up to 50% of energy, compared with a conventional bus drive-train.
The chasis of the new bus is a standard 12 metre with 18 tonne combined weight, while the new drive-train produces up to 120 kW of power, can travel up to 65 kph and with a full tank can travel 250km before refuelling.
The hydrogen is stored on board in 350 bar compressed cylinders and carries around 20kg of hydrogen when full.
