We have been hearing about drastically shrinking oil reserves for a long time. Toyota has found a way to follow the diesel life that is about to come. Hydrogen cars seem to be the future of the automotive industry. Especially since electric cars do not meet the hopes placed in them so far.
Technology straight from submarines
Toyota designers believe that hydrogen cars are the future of the automotive industry. It even turns out that the company has had developed effective technologywhich was taken from the design of submarines. Moreover - the solution is is already produced on a massive scale and was baptized as Toyota Mirai.

Hydrogen cars - construction
The achievements of Toyota designers include, above all, the fact that They did it significantly reduce the size of the technology. It has been used so far in the most modern and conventional submarines. With the difference that there it occupied half of the ship's engine room and an entire additional hull segment. The Japanese locked her up in 4,89 meters Toyota Mirai.

The magic of chemistry
The entire set of fuel cells is actually there a small power plant. However, turbines and a steam boiler, for which it is necessary, are not used to power the vehicle carbon and/ or the heat of the nuclear reactor. Normal was used in this case chemical reactions. More specifically, the cold hydrogen oxidation reaction.
A small power plant
Thanks to this process cold oxidation of hydrogen it is possible to produce electricity to power the vehicle on an ongoing basis. For this purpose, you only need access to oxygen, hydrogen as well fuel cells. Toyota engineers significantly reduced the size of this technology because, unlike submarines, Mirai only needs to take hydrogen with it. It is able to obtain the necessary oxygen from the air.
In practice, it is not so colorful
In practice, a great deal of engineering skill was required to achieve the compact size of the entire power system. First of all, because of the specificity of hydrogen. It is a gas considered to be very unstable. This means in practice existence enormous risk of catching fire. Additionally particles are smallwhich made it difficult to store hydrogen. Therefore, the greatest challenge was not only miniaturization of componentsbut also exceptionally designed tight installation for the storage of this gas.

Polymer fiber tanks
For this reason, it was decided to hydrogen cars they were equipped with lightweight tanks made of polymer fibers. They have a capacity of 122,4 liters, in which it is stored gas under pressure of 700 barthat. In order to ensure the greatest possible safety, the tanks were subjected to various tests. For example, large-caliber projectiles were fired at them. All this to make sure you are driving it will not ignite.
Advantage over "electricians"
It should be noted that hydrogen cars they have one big advantage over electricians. This mainly concerns the feeding process. We will fill the Toyota Mirai with gas in the same way as it is done traditional LPG gas charging. The driver will be informed that he is running out hydrogen. It is enough for him to drive to a gas station, fill up the gas and be able to continue on the road. This is a nice distinction from long-term charging of electric batteries.
Not only Mirai
Hydrogen cars Toyota's offer will not be limited to just one model. The Japanese are already working on the implementation to the offer the hydrogen SUV. Ultimately, it is supposed to pass even 1000 km on one tank. We are looking forward to the first prototype!
