To fuel a hydrogen car from water, electricity is used to generate hydrogen by electrolysis. The resulting hydrogen is an energy carrier that can power a car by reacting with oxygen from the air to create water, either through burning in a combustion engine or catalyzed to produce electricity in a fuel cell.
Instead of being filled up with petrol or diesel, the Mirai (the word is Japanese for ‘future’) is powered by the most common element in the universe — hydrogen.
The gas is inserted into the car’s tank just as you might use a petrol pump, and then, through the wonders of a fuel cell — which produces a chemical reaction between the hydrogen and oxygen in the air — it is converted into electricity, which in turn powers the car.
The Toyota Mirai (From mirai (未来?), Japanese for “future”) is a hydrogen fuel cell vehicle, one of the first hydrogen fuel-cell vehicles to be sold commercially. The Mirai was unveiled at the November 2014 Los Angeles Auto Show. Toyota planned to build 700 vehicles for global sales during 2015.
Under the United States Environmental Protection Agency (EPA) cycle, the 2016 model year Mirai has a total range of 502 km (312 mi) on a full tank, with a combined city/highway fuel economy rating of 66 mpg-US (3.6 L/100 km; 79 mpg-imp) equivalent (MPG-equivalent), making the Mirai the most fuel efficient hydrogen fuel cell vehicle rated by the EPA, and the one with the largest range.
Hydrogen fuel cell vehicles could change mobility forever, around the world efforts are being made to harness the power of hydrogen, the most abundant element in the universe.
Recognizing hydrogen’s vast potential as a clean energy source, Toyota is actively developing and producing fuel cell vehicles (FCV). We believe hydrogen can help us contribute to the next 100 years of the automobile.
Through the chemical reaction between hydrogen and oxygen, fuel cell vehicles generate electricity to power a motor. Instead of gasoline they are fuelled by hydrogen, an environment-friendly energy source that can be produced from a variety of raw materials.
Toyota’s efforts to make sustainable mobility a reality with hydrogen started in 1992, even before the release of the Prius. In 2002, Toyota began the world’s first limited sales of a fuel cell vehicle, the “Toyota FCHV”, in Japan and the U.S. Toyota has also made use of its hybrid vehicle technology in the development of fuel cell vehicles.
The Mirai features the Toyota Fuel Cell System, which combines fuel cell technology with hybrid technology.
The system is more energy efficient than internal combustion engines, and offers excellent environmental performance without emitting CO2 or other harmful substances during driving. At the same time, the system gives vehicles convenience on a par with conventional gasoline engine vehicles, thanks to a cruising range
*1 of roughly 650 km and a refueling time of about three minutes
*2. In addition, the Mirai can serve as a high capacity power supply during emergencies. It is capable of supplying roughly 60 kWh
*3 of electricity, with a maximum DC power output of 9 kW
*4. When a separately-sold power supply unit is connected, the Mirai converts the DC power from the CHAdeMO power socket located inside the trunk to AC power and can power a vehicle-to-home
*5 system or a vehicle-to-load system. Consumer electronics can also be connected directly and used from the interior accessory socket (AC 100 V, 1,500 W).
