Hydrogen engine cars.
Hydrogen engine cars are cars that use hydrogen engines as a power source. The fuel used in general engines is diesel or gasoline, and the fuel used in hydrogen engines is gaseous hydrogen. Hydrogen engine vehicles are a truly zero-emission means of transportation, emitting pure water, which has the advantages of no pollution, zero emissions, and abundant reserves.
Advantages: The discharge is pure water, and it does not produce any pollutants when driving.
Disadvantages: The cost of hydrogen fuel is too high, and the storage and transportation of hydrogen fuel is technically very difficult, because the hydrogen molecules are very small and can easily escape through the casing of the storage device. The most fatal problem is that hydrogen extraction requires electrolysis of water or natural gas, which also requires a lot of energy and cannot fundamentally reduce CO2 emissions unless nuclear power is used to extract it.

In recent years, there has been an endless stream of information on new energy technologies for automobiles. Among them, some of the acts of privately collecting money in the name of this, such as the "water hydrogen engine" of a certain unit in a certain place last year**, etc., made people start to have doubts about this. However, the concept of hydrogen fuel cell vehicles has gradually entered people's field of vision, especially after Honda, Toyota, Hyundai, etc., have successively launched their own hydrogen fuel cell models, and this new energy vehicle seems to be getting closer and closer to the public.
In fact, when it comes to hydrogen fuel cells, it is not a new technology that has only been invented in recent years. It appeared in the field of American aerospace science and technology in the 60s of the 20th century. In 1965, the world's first hydrogen fuel cell, manufactured by the American Electric Company, was officially used in the American Gemini 5 spacecraft.
So the idea that hydrogen fuel cells are not ** is simply nonsense! The biggest advantage of hydrogen batteries is zero emissions, which is definitely a boon for increasingly stringent emission standards. In addition to zero emissions, hydrogen fuel cells also have high endurance, fast fuel replenishment, and ultra-low noise, which are not available in new energy vehicles at present.
In the decades that followed, Canada formally established a company engaged in hydrogen fuel cell research. Thanks to the efforts of this company, hydrogen fuel cell technology has made a great breakthrough and now has an absolute global technology monopoly. The company, called Ballard, is a global leader in the hydrogen fuel industry.
Even many car companies, including Mercedes-Benz, Volkswagen, Ford, Toyota, and Honda, are using Ballard's technology. China's earliest company, Guo Hong Hydrogen Energy, also officially signed a cooperation agreement with Ballard in 2016.
Guo Hong Hydrogen Energy will become Ballard's main partner in the Chinese market, and is committed to promoting the popularization and application of hydrogen fuel cells in China. But if it is to be truly used in civilian vehicles, there are still many obstacles to be broken on this road. One of the most important issues is how to ensure that hydrogen remains stable and safe throughout the storage process.
Hydrogen is an extremely flammable gas that is highly corrosive and can cause fatal damage to storage containers. Therefore, the hydrogen storage technology of hydrogen fuel cell vehicles is still one of the important bottlenecks faced by many enterprises. In addition, it is necessary to establish a complete set of industrial chains, such as hydrogen acquisition, purification, storage, transportation, and the construction of hydrogen refueling terminals.
This requires a significant capital cost to achieve. To sum up, hydrogen fuel cell vehicles, a new energy vehicle technology, have not yet been popularized. Although hydrogen fuel cell technology is considered to be the next generation of epoch-making new energy technology after new energy vehicle technologies such as lithium batteries.
However, in order to achieve its popularization, many problems need to be solved, including technical problems and personnel training. Only the progress of talents can promote the faster development of hydrogen fuel cell technology.

Hydrogen fuel cell vehicles are now low in stock, but in fact, the starting time of hydrogen fuel cell and pure electric technology is the same.
The state has successively introduced various new energy incentive policies, such as a number of preferential policies such as car purchase subsidies, priority licensing, and unlimited driving restrictions, so that pure electric vehicles have become popular rapidly. Hydrogen fuel cell vehicles are not even visible in many areas.
In fact, hydrogen fuel cells cannot be promoted on a large scale, and the most important reason is that the cost is too high. Compared with foreign technologies, there is still a relatively large gap between our country in terms of basic key materials and the life, cost, and mass production consistency of hydrogen fuel cells.
In particular, some of the core materials of hydrogen fuel cells need to rely on imports, and the materials that have been localized have not yet completely replaced imported materials.
In addition, hydrogen fuel cells have not yet formed a scale and cannot share the cost, resulting in the cost of fuel cell vehicles is more than twice that of fuel vehicles, and they cannot be sold without policy subsidies.
Nowadays, the countermeasure adopted by the state is to replace the support program with awards, which can focus on conquering the core technology, and I believe that hydrogen fuel cells can be localized as soon as possible.

<> "Why Hydrogen Energy is Rising as a New Energy."
Hydrogen vehicles & methanol pure vehicles are identified as the two development directions of new energy drive technology, and they are often compared to each other. And the reasons why methanol fuel still hasn't risen are:
1. The calorific value of methanol is about 19464 kilojoules per kilogram, which is the standard calorific value of gasoline, which is close to 10,000 kilojoules lower than fuel ethanol. The calorific value of the fuel directly determines the [torque] formed by the conversion, and the low calorific value fuel for the engine with the same displacement is equal to the low torque, and the torque speed is 9549 horsepower.
2. Methanol will produce formic acid in an inadequate combustion state, which will damage the properties of engine oil to a certain extent; However, the use of methanol has to be driven at high revs as a normal state and buried state, and the result is naturally that the engine is not durable.
Summary: Methanol fuel vehicles have actually been popularized in a small range of the aftermarket more than ten years ago, but they have been gradually eliminated by the market due to too many problems and high practical application costs.

The advantages of hydrogen fuel cell vehicles are: zero emission, reducing the pressure on car companies to reduce emissions, a single hydrogen refueling only takes a few minutes, can travel 1,000 kilometers, long battery life, and strong low-temperature performance.
In the process of hydrogen combustion, only water vapor is emitted, and no polluting waste gases such as carbon dioxide are emitted, which can be circulated indefinitely without polluting the environment. The fuel efficiency is very high, converting 60% to 80% of hydrogen into driving energy, compared to only 25% to 30% of the conversion rate of ordinary cars.
The biggest advantage of hydrogen fuel cell vehicles using hydrogen as an energy source is that it can produce water vapor with oxygen in the air, which effectively reduces the gas pollution caused by other fuel vehicles.
What is the principle of hydrogen fuel cell
The basic principle of hydrogen fuel cells is the reverse reaction of electrolysis of water, with hydrogen and oxygen supplied to the anode and cathode, respectively. The hydrogen diffuses through the anode, and after the electrolyte reacts, the released electrons reach the cathode through an external load.
Hydrogen fuel cells are environmentally friendly. It is carried out through electrochemical reactions, instead of combustion (gasoline and diesel) or energy storage (batteries). The most typical traditional backup power solution will release pollutant gases and dust such as COX, NOX, SOX and so on when burned.
The fuel produces only water and heat. If hydrogen is produced from renewable energy, the entire cycle is a complete process that does not produce harmful substances.
Hydrogen energy vehicle hydrogen energy is a secondary energy source, which is produced by using other energy sources in a certain way, unlike coal, oil and natural gas, which can be extracted directly from the ground and almost completely rely on fossil fuels as an ideal new energy source of energy, it has the following characteristics: l, the lightest weight element. In the standard state, when the density is , it can become a liquid, and if the pressure is increased to hundreds of atmospheres, the liquid hydrogen can become metallic hydrogen. >>>More

The annual inspection of the car is what every car has to go through, but the new car can enjoy the six-year exemption policy, as long as it meets the regulations, it can be exempted from the annual inspection for six years. For the annual inspection, fuel vehicle owners can be said to be familiar with the road, after all, so many years of annual inspection are fuel vehicles, but new energy vehicle owners are a little puzzled, new energy vehicles are obviously different from fuel vehicles, why do you still have to inspect it? The exhaust gas index of fuel models is a headache for car owners, and it is easy for models of the past year to be planted in the exhaust gas index. >>>More
