FCVs are powered by fuel cells, which generate electricity from hydrogen, which is not only environmentally friendly and highly energy-efficient, but can also be produced using a variety of readily available raw materials. Thanks to these characteristics, fuel cell vehicles are ideal for achieving sustainable mobility. Therefore, Toyota is striving to make this vehicle technology widely available as soon as possible.
At a steady cruising speed, the motor is powered by energy from the fuel cell. When more power is needed, for example during sudden acceleration, the battery supplements the fuel cell's output. Conversely, at low speeds when less power is required, the vehicle runs on battery power alone. During deceleration the motor functions as an electric generator to capture braking energy, which is stored in the battery.
A practical sedan-type next-generation fuel-cell concept vehicle fueled by hydrogen, a promising source of CO2 emission-free energy that can be produced from a variety of sources and can be easily stored and transported. This concept model is a highly practical fuel-cell vehicle (FCV) that is planned for launch in about 2015.
With the fuel-cell unit located beneath the specially designed body, the vehicle can accommodate up to four passengers and boasts impressive luggage space. The fuel cell stack, consisting of a 70MPa high-pressure hydrogen tank, has been improved to provide a cruising distance of approximately 700 km or more (under the JC08 test cycle; according to TMC).
