Hydrogen fuel cell vehicles are considered as zero emission vehicles.
These vehicles combine hydrogen fuel and oxygen from the air to produce
water and electricity. The electricity is then used to power the
electric motor which powers the vehicle.
Honda motors has developed a concept fuel cell car called the "Honda
FCX" which will become a limited production car in 2008. Honda has
equipped the FCX with a fuel stack and an ultra capacitor along with
high pressure hydrogen tanks. The fuel cell stack serves as the main
power source while the ultra capacitor serves as the storage unit for
The Honda fuel stack consists of the PEMFC (Proton Exchange Membrane
Fuel Cell) and has a total maximum output of 86kW. The water produced
when hydrogen and oxygen are combined, is used in the humidification
system. The fuel cell system is located under the floor and the high
pressure hydrogen tanks are positioned under the rear seat. The ultra
capacitor is positioned at an angle behind the rear seat to ensure that
luggage space is not lost from the trunk....
