  • Fuel cell tractor Comet 4FC
    Fuel cell tractor Comet 4FC

    Comet 4FC

    The Comet 4FC is the ideal solution for baggage handling in sorting areas, on the apron and for indoor industrial use. With its electrical drive and power generation using a fuel cell system by Plug Power the towing tractor is CO2 emission free and thus ideally suited for indoor use as well as continuing powerful operation on the airport apron.

    The built in fuel cell generates electrical energy through a chemical reaction of hydrogen and oxygen and provides power for the conventional electrical engine of the vehicle, clear water and heat are the only emissions being generated in this process. The refuelling with hydrogen takes only a few minutes thus the vehicle qualifies for 24/7 operation.
