The Toyota Mirai uses hydrogen – an important future energy source – to generate power.
The vehicle mixes environmental performance, with the convenience and driving pleasure that is expected of any car.
The Miraiuses Toyota Fuel Cell System (TFCS), which features both fuel cell technology and hybrid technology, and includes Toyota’s new proprietary FC Stack and high-pressure hydrogen tanks.
The car is much more energy efficient than internal combustion engines and emits no CO2 or pollutants when driven.
Drivers can also expect the same level of convenience offered by gasoline engine vehicles, with a generous cruising range and a hydrogen refuelling time of about three minutes.
Are Hydrogen fuel cell cars safe?
Hydrogen cars are perfectly safe. According to the Canadian Hydrogen and Fuel Cell Association’s website, “Hydrogen has been proven to be as safe as or even safer than other flammable fuels such as gasoline or natural gas.”
The precaution however is that, “…hydrogen can leak easily and ignite at relatively low temperature.”
The 2017 Toyota Mirai has proper safety features in place, which are described in a four-point process on how to keep the hydrogen from exploding:
- Leak-proof tanks hold the hydrogen
- In case of a collision, sensors stop the flow of hydrogen
- Any leaked hydrogen is quickly dispersed
- Hydrogen escapes safely into the atmosphere
Hopefully, these safety measures will change the minds of those who are unsure about hydrogen fuelled cars.
Toyota Mirai Features:
The vehicle features a fusion of fuel cell technology with hybrid technology. The system uses Toyota-developed components including the Toyota FC Stack, FC boost converter, and high-pressure hydrogen tanks.
Toyota FC Stack:
The new Toyota FC Stack achieves a maximum output of 114 kW (155 DIN hp) and a world-leading power output density of 3.1 kW/L (2.2 times higher than that of the previous Toyota FCHV-adv limited-lease model).
FC Boost Converter:
A new compact, high-efficiency, high-capacity converter has been developed to boost power generated in the Toyota FC Stack to 650 volts.
High-pressure Hydrogen Tanks:
Tanks with a three-layer structure made of carbon fibre-reinforced plastic and other materials are used to store hydrogen at a very high pressure of 70 MPa (70 megapascals, or approximately 700 bar).
The Japanese car manufacturer is offering three years’ of complimentary fuel or $15,000 worth of hydrogen. New Mirai owners, or lessees, will be provided with a debit card, which they can use at fuelling stations.
You’re not going to find a hydrogen station as easily as a gas station, however, if you do find a hydrogen station, it will only take about five minutes to fill up. On just one refuelling, you’ll be able to travel approximately 312 miles.
