Do you still remember the water-hydrogen car with "no refueling, no charging, and a cruising range of up to 1000 kilometers"? Although this is a "joke", the hydrogen car has been under intensive research and development.So, hydrogen car, how far away from us? Why do many people dare not ride hydrogen car?

Compared with fuel vehicles, hydrogen vehicles have many advantages, such as no pollution, zero emissions, and good comfort. However, for hydrogen vehicles, many people generally hold a wait-and-see attitude towards their safety compared to the advantages of hydrogen refueling stations with a 3-minute battery life of more than 600km.

Xiao Bian asked some friends: "Would you like to ride in a hydrogen car?" Many people's answer is "run with a hydrogen tank, is it safe?" From the structure of many hydrogen cars can be seen, the original fuel tank was replaced by a hydrogen tank, generally located between the chassis under the seat.Is it safe to sit under a "big hydrogen tank?

Although the material of the hydrogen storage tank is usually aerospace-grade material, it is relatively thick, and the bullet cannot penetrate, but if a large car collision accident occurs, is the strength of the hydrogen storage tank really enough?Gasoline is a liquid, hydrogen is a gas, the consequences of leakage is completely different.

According to relevant information, hydrogen is one of the most easily leaked gases. Hydrogen may deflagrate at a concentration of 4%-70%. A car with 10% hydrogen leakage can kill people within 10 meters or even 20 meters in an instant of ignition and leak in tunnels and underground parking lots. That may be a catastrophe.

If there is still a chance to escape from the spontaneous combustion of the tram, then the hydrogen leak is simply a mini temperature and pressure bomb.Any leak on the pipeline could cause a violent deflagration and put an entire building on a plane. Unless you only live in a big villa, don't go to work, don't go shopping.

Therefore, some people say that there are many three-electric systems for hydrogen-energy vehicles, and a hydrogen storage tank and reactor have been added. This technical scheme is more rubbish than the current extended range.More importantly, hydrogen vehicles also make up for the two shortcomings of "the explosion power of the oil truck is too small and the spontaneous combustion of the tram is too slow.

In addition to the possible explosion risk, hydrogen embrittlement is no solution.Unless the hydrogen is cooled and pressurized into a liquid, the hydrogen atoms lose their high energy state. However, it is impossible to let a hydrogen car run with a cold storage every day!

On the other hand, hydrogen cars may not be suitable for small cars. No matter how many hydrogen refueling stations there are, this fact cannot be changed. After all, it is determined by the physical and chemical properties of hydrogen itself.At least passenger cars and heavy trucks are suitable for using hydrogen energy and are relatively safe to operate.
