It is reported that the water-hydrogen engine has officially rolled off the production line in the city, which means that the vehicle's water-borne hydrogen can be produced in real time, and it only needs to add water to drive.
Pang Qingnian, chairman of the board of directors of Youngman Auto Group, demonstrated this technology in an earlier interview, which is roughly as follows:
“Connect the water pipe to the faucet and control the car. The two water tanks on the top were filled. After filling, the driver started the vehicle. The water droplets in the transparent hose connected between the water tank and the hydrogen fuel cell were flushed by the gas and the engine was started. The vehicle was driven out of the workshop. ”
At that time, Pang Qingnian pointed out the basic principles and characteristics of this technology. It is organized as follows:
▎The special conversion settings in the car can convert water into hydrogen, and then input it into the hydrogen fuel reactor (there is a special catalyst in it, and water can be converted into hydrogen under the action of this special catalyst ), a hydrogen fuel cell, generates electrical energy that then drives the vehicle's motor and engine.
▎The "Youth Hydrogen Fuel Vehicle" has a cruising range of more than 500 kilometers without refueling or charging, and only adds water, and the cruising range of a car can reach 1,000 kilometers.
▎Pang Qingnian said that this catalyst can convert water into hydrogen at almost zero cost and generate electricity through hydrogen fuel cells.
1. Youth Auto Group’s CNKI patents are zero
Before the technology is clear, we will not kill such a company with a stick, but it seems ridiculous no matter how you look at it. . On CNKI, Chejujun did not find any technical articles related to the "hydrogen fuel vehicle" related to the new energy sector of Youth Auto Group, not even the patents that technology companies are most concerned about! As a major breakthrough, Che Jujun strongly suggested that they protect their pioneering technology.
Okay, you know Che Jujun is joking.
Anyway, judging from Che Jujun’s experience, a breakthrough technology never rises from the ground, but should be the result of countless people’s accumulation over time, but Che Jujun did not see this in the case of Youth Automobile Group.
For comparison, Zhejiang Geely Automobile Research Institute Co., Ltd. has nearly 10,000 patents (indexed by the applicant), which some people have criticized as lacking technology.
2. Is the "Youth Hydrogen Fuel Vehicle" feasible?
Let’s talk about the “Youth Hydrogen Fuel Vehicle” itself. In fact, it is not impossible to convert water into hydrogen. The simplest method of producing hydrogen is dilute acid and active metals such as zinc, iron, sodium, aluminum, etc. In industry, hydrogen is produced by methods such as electrolysis of water and decomposition of methane.
However, according to Pang Qingnian’s introduction, they used a catalyst, so it was most likely a reaction of aluminum plus sodium hydroxide plus water. Its chemical reaction formula is as follows:
2Al 2NaOH 2H2O = 2NaAlO2 3H2↑
However, the statement that "water can be converted into hydrogen at almost zero cost" is nonsense. Is it possible to directly convert water into hydrogen without the catalyst being consumed (or consumed very slowly)? You must know that water is a stable substance, and it takes energy to convert it into an unstable substance like hydrogen (water first needs to absorb energy when its molecules are destroyed to become hydrogen atoms and oxygen atoms). Who will provide the energy for this conversion? By meditation?
In addition, how to calculate the energy conversion rate? Without refueling or charging and only adding water, the cruising range is more than 500 kilometers, and the cruising range of a car can reach 1,000 kilometers. This is a very eye-catching performance.
To what extent is this possible? The Toyota Mirai can store 6kg of hydrogen and has a cruising range of 650 kilometers; the Honda Clarity can store 6kg of hydrogen and has a cruising range of 700 kilometers; the Hyundai Nexo can store 6.33kg of hydrogen and has a cruising range of 800 kilometers; the Hyundai Tucson ix can store 5.63kg of hydrogen and has a cruising range of 594 kilometers. .
We assume that the technical strength of the "Youth Hydrogen Fuel Vehicle" in "converting hydrogen into electrical energy, and the electrical energy is reflected in the cruising range" is equivalent to the above-mentioned cutting-edge and quite mature products, which means that it at least needs to be manufactured 7.91kg of hydrogen is produced.
According to the above formula, they need to invest at least 71.2kg of Al and 105.5kg of NaOH, which is a lot of consumption (this is assuming that the reaction is ideal and a complete reaction occurs). It is an interesting question whether the cost has increased or decreased compared to traditional conversion methods.
Car gathering summary
In addition, there are people who continue to uncover risk information about young people’s cars. There are 686 pieces of risk information, 29 pieces of information on persons subject to execution, and 46 pieces of breach of trust information. This year, 1 On March 7 and 8, it was listed as a breach of trust by the Shanghai Minhang District People's Court and the Changzhou Zhonglou District People's Court respectively. Che Jujun believes that this issue should be looked at separately. It does not mean that if you do not do well in business, you will lose your skills.
In short, the country has mainly used fossil fuel production, water electrolysis production and by-product hydrogen from the chlor-alkali industry in hydrogen production for many years. Although the future development direction of hydrogen production is electrolysis of water to produce hydrogen, with the help of special catalysts, it is simply nonsense to achieve "water"-driven fuel vehicles with "zero cost and ultra-long battery life".
This is how bold people are and how productive the land is.
