Is it true that hydrogen fuel cell cars explode more easily than other cars?

Since the beginning of this year, one of the four major news plates in the market is the hydrogen energy plate, and every once in a while there will be big news. Before this, there was a century joke about Nanyang hydrogen car, and various leading figures appeared constantly in the market.

1. Toyota and Hyundai Motor announced that they would stop supplying hydrogen-powered vehicles in some areas.

Five days ago, on June 10, an explosion occurred at a hydrogen refueling station in Oslo, injuring two people. Toyota and Hyundai Motor immediately announced that they would stop selling hydrogen fuel cell vehicles in Norway.

At the same time, more than 10 stations in Norway were closed, and Uno-X, the operator of hydrogen refueling station, also announced the suspension of local hydrogen refueling service.

Second, Toyota still insists on optimistic about hydrogen energy vehicles.

Toyota said that the explosion of hydrogen refueling station will not change Toyota's view on hydrogen fuel cell vehicles, and insisted that hydrogen fuel cell vehicles are at least as safe as ordinary cars.

Third, hydrogen fuel explosion is more difficult.

1, advantages

Charging can be completed in 3 minutes, and only water is discharged, and there is no waste gas.

2. Process

Hydrogen fuel cell is a kind of power generation device that directly converts chemical energy into electric energy.

3, the critical point of hydrogen explosion

Hydrogen has the greatest buoyancy and diffusibility, and its diffusion speed is 3.8 times that of natural gas, which makes the leaked hydrogen rise rapidly and spread rapidly in all directions, making it difficult to reach the concentration required for explosion.

Hydrogen itself is much more dangerous than gasoline. For oxyhydrogen mixed with air, its explosion point can't be in the car. In other words, no matter how it gathers, it can't reach the explosion point and form an explosion.

Fourth, the current problems.

1, the explosion accident pushed the hydrogen truck to the forefront, and the safety issue became the focus.

2, the problem of hydrogen itself

It makes everyone afraid to be aggressive about the development of hydrogen energy vehicles. Because hydrogen is a natural active, flammable and explosive gas, it will be a danger source whether in gas stations or cars. How to use it safely is a big problem. So this is also the reason why up to now, this very full ideal has not been well practiced.

3. How to promote efficient and environmentally friendly new energy vehicles?

First, the safety of hydrogen energy is difficult to solve.

After all, even electric vehicles with low technical barriers have been experiencing spontaneous combustion recently.

Second, the prospect of hydrogen energy is good, but it should develop steadily.

The Automotive Engineering Association clearly pointed out in the technical roadmap of energy-saving and new energy vehicles that there will be more than one million hydrogen fuel cell vehicles in China by 2030, and it is still in its infancy, so we must not give up eating because of choking.
