Chapter 957

"Energy is the foundation of economic development. Without the development of the energy industry, there would be no modern civilization. Mankind has been making unremitting efforts to use energy more effectively. In our history, we have many kinds of energy available for us to use. And now, we can use more energy~"

Baduwa is in a good mood now.

Catherine wanted to touch the car, but because she was wearing a black one-piece tights, Catherine's hands were completely wrapped in black latex, so she couldn't feel the feeling of this car.

Of course, Catherine wouldn't bother to take off her clothes for this little trouble.

"You said, is it a fuel cell car?"

Facing the other party's explanation, Catherine selectively ignored it, but the fuel cell was attractive to Catherine.

"A fuel cell is a power generation device that directly converts the chemical energy in the fuel and oxidant into electrical energy. Fuel and air are fed into the fuel cell separately, and electricity is magically produced. It looks positive and negative. And electrolyte, etc., like a battery, but in fact it cannot'storage' but a'power plant'. Compared with the previous lead battery, the energy system of this car is more advanced and the system is more convenient."

Baduwa is still a bunch of nonsense.

But after Catherine heard the other party's plan, her eyes couldn't move away.

Perfect!

This car is perfect for myself!

If it is really a fuel cell, why not?

Why did I forget such a thing as a fuel cell to pull the wind?

There have been many revolutionary changes in the way of using energy in history. From the original steam engine to the steam turbine, high-pressure steam turbine, internal combustion engine, and gas turbine, every change in the way of energy utilization has greatly promoted the development of modern civilization.

With the development of modern civilization, people have gradually realized that traditional energy utilization methods have two major drawbacks.

One is that the chemical energy stored in the fuel must first be converted into heat energy before it can be converted into mechanical energy or electrical energy. Due to the limitations of the Carnot cycle and modern materials, the efficiency obtained at the machine end is only 33 to 35, and more than half of the energy is in vain. Land is lost.

Second, the traditional energy utilization methods have caused huge amounts of waste water, waste gas, waste residue, waste heat and noise pollution to the human living environment. For the power generation industry, although the technology adopted is constantly upgrading, such as the development of ultra-high pressure, supercritical and ultra-supercritical units, and the development of fluidized bed combustion and integrated gasification combined cycle power generation technology, this effort The result is: huge unit scale, ultra-high-voltage long-distance power transmission, investment increase, the overall energy efficiency of users is still only about 35, large-scale pollution still has not been fundamentally resolved.

However, there is a technology that enables energy to have higher energy efficiency without polluting the environment. This is fuel cell power generation technology.

Seeing Catherine not speaking, Badu thought that Catherine didn’t understand this technology, and explained: “The energy used by this car is hydrogen energy. The working principle is probably that the hydrogen used as fuel is used in the fuel cell of the car. , It chemically reacts with the oxygen in the atmosphere to produce electrical energy to start the motor, and then drive the car. Note that this is a chemical reaction, not direct combustion, so the silence you always wanted, Miss Edson, can also be guaranteed. This car is the same as my previous lead-battery electric car, and it has more torsion and climbing power. You will love it."

"In addition, methanol, natural gas, and gasoline can also replace hydrogen because hydrogen is indirectly extracted from these substances. However, this will also produce very little carbon dioxide and nitrogen oxides, but in general, this type of chemical reaction is in addition to electricity. In terms of only producing water, it is also very useful in terms of environmental protection."

Having said this, Baduwa approached Catherine and said in a low voice: "Although this technology is provided by GM, we are inspired by the moon landing plan. They also use this battery..."

Is it so?

Catherine was ridiculous.

"Your technique really works?"

Catherine wanted to give it a try, but he hesitated, then Catherine asked again: "Is your car safe?"

"Probably... it's safe."

probably? !

Also, what is the hesitation in the middle!

"The density of hydrogen is very low. Even if the fuel is stored in liquid form in cryogenic cylinders or compressed gas cylinders of hydrogen fuel vehicles, the energy that can be stored in those spaces is very limited, right?"

Catherine went around the car and tried to find the "fuel tank".

"Uh--"

Baduwa didn't expect that Catherine would tell the defect of the fuel cell vehicle at once, and for a while, she didn't know what to say.

He had no idea that Catherine had knowledge of another world line.

Even in the 21st century of Catherine, hydrogen cars are very restricted compared to other cars. Some studies have used special crystals to store hydrogen in a higher-density environment, and it is safer, but that is not what the current technology can have.

"So the method we think of now is to use hydrogen reformers to extract hydrogen from traditional fuels such as methane, gasoline and ethanol. In this way, we can store more."

"Of course, many environmentalists are not interested in this idea because it relies on fossil fuels. However, this is an effective reorganization process. Using reorganized gasoline or ethanol to drive fuel cells is still more effective than using internal combustion engines."

Catherine also felt reliable.

"The school district can use such a car."

Catherine's words, in the school district's words, can be compared to the so-called "sacred decree" in a sense. When they heard Catherine's words, Baduwa smiled.

"But we are not without problems... It costs a lot to make reliable fuel cells. We are now working on ways to make the cost of fuel cells as cheap as possible, and this must also ensure that they are hard enough to withstand impact. And the basic problem of vibrating these cars... My car is considered a test product, but I only dared to drive it in the school district where there are not many cars. The design of fuel cells is mostly fragile, so it can't be stored in many cases. In addition, many designs require rare substances such as platinum as accelerators. Although the work is smoother, accelerators may contaminate the purity of hydrogen and are not conducive to the supply of hydrogen. In these studies, we are all struggling... "

Badu shook his head, seemingly regretful of these studies.

"Hydrogen can be used as a carrier of energy rather than an energy source. If you study this, it is still too early to make money. Hydrogen must be extracted from fossil fuels or other energy sources, so it will cause energy loss-because from other energy sources to hydrogen and back again The conversion to energy is not 100% effective. You will not forget the law of conservation of energy, right?"

Catherine hit them mercilessly.

"Although you have improved, this increase in efficiency by 1 means a sharp increase in the cost of more than 10 or even more than 20. This is not worthwhile. Calculate that someone wants to buy it cheaply, but you may agree?"

"But if it's a hybrid car, it should be possible..."

Catherine murmured.

Broadly speaking, a hybrid vehicle refers to a vehicle that has at least two power sources and uses one or more of them to provide part or all of the power.

However, in actual research, hybrid vehicles mostly use traditional internal combustion engines and electric motors as power sources, and use two systems of heat and electricity to drive the car. The internal combustion engine used has both diesel and gasoline engines, so traditional gasoline or diesel can be used, and some engines have been modified to use other alternative fuels, such as compressed natural gas, propane and ethanol fuels. The electric power system used includes highly efficient and enhanced electric motors, generators, and batteries.

In Catherine's view, the research funding for vanadium batteries is not yet in place, but with fuel cells at this time, maybe you can play around.

"Hybrid?"

"The car I need does not have to be the most handsome or the most attractive, but it must be the safest and most comfortable..."

Catherine circled the car like this.

"Those racing parties who know about drag racing every day may be ashamed. Those who are handsome may be robbed anytime. It is still the safest like me..."

When Catherine was muttering, she didn't know that the communication device on the car was also turned on, and Catherine's muttering was even heard by people from General Motors...

"Oh, oh. That's a good idea. Even if you have money, you have to live to enjoy it!"

Badu sighed.

"Well... do you want a three-energy, dual-engine hybrid battery?"

Using gasoline, fuel cell and battery three power sources, Catherine thinks this idea is good.

After adopting compound power, the maximum power of the internal combustion engine can be determined according to the average required power. At this time, it is working under the optimal working condition with low fuel consumption and low pollution. When the power of the high-power internal combustion engine is insufficient, the battery is used to supplement; when the load is low, the surplus power can generate electricity to charge the battery. Because the internal combustion engine can continue to work, the battery can be continuously charged, so its stroke is the same as an ordinary car, and it will not be reduced. ~lightnovelpub.net~ And because of the battery, it can easily recover energy during braking, downhill, and idling.

In Catherine's view, when high power is needed, gasoline is used for power, fuel cells are usually used, and then batteries are used.

Because the fuel cell is convenient enough and the battery can also recover energy, it must be very cool.

"Well, for the investment in vanadium batteries, we should use a part of it to invest in fuel cells... When the technology matures, gasoline or something will be used as a fuel for hydrogen production in the future."

Catherine was thus determined.

The third is complete!

Go to Wudang Mountain tomorrow, hehe.
