Chapter 957 fuel cells and cars

"Energy is the foundation of economic development. There is no modern civilization in the development of energy industries. Human beings have been making unremitting efforts in order to make more energy. In our history, we have many energy resources for us, And now, we can use more energy more ~ ​​"

Baduva is now very mood.

Catherine wanted to touch this car, but because of the black lace, Catherine's hand was completely packaged by black latex, so I couldn't feel the feeling of this car.

Catherine, of course, will not take off his clothes for this little trouble.

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

In the face of the interpretation of the other party, Catherine selectively ignored, but the fuel cell, it was attractive to Catherine.

"The fuel cell is a power generation device that will be directly converted into electrical energy in the fuel and oxidant. The fuel and air are fuel cells, and the electricity is wonderfully produced. It is a positive and negative pole from the outside. And electrolyte, etc., like a battery, but it is essentially unable to "storage" but a 'power plant', which is more advanced relative to the previous lead battery, the energy system of this car is more advanced, and the system is also more convenient. "

Baduva is still a bunch of nonsense.

But Catherine will not drive after hearing the other party's plan.

Perfect!

This car is just perfect for yourself!

If it is really a fuel cell, why can't you?

How do you forget the fuel cell such as a fuel cell?

Historically uses energy to have several revolutionary changes, from the original steam engine to steam turbine, high-pressure steam turbine, internal combustion engine, gas turbine, and each energy utilization method, greatly promoted the development of modern civilization.

With the development of modern civilization, people gradually recognize two major illnesses in traditional energy utilization.

First, the chemical energy stored in the fuel must first turn into thermal energy to be converted into mechanical energy or electrical energy, the restriction of the Carano circulation and modern materials, only 33 ~ 35, more than half of the energy percentage The land loss is lost.

The second is that traditional energy utilization methods have caused huge amount of wastewater, exhaust gas, waste slag, waste heat and noise pollution.

For the power generation industry, although the technique adopted is constantly upgrading, such as the development of super high pressure, supercritical, super-critical units, it has developed fluidized bed burning and overall gasification combined cycle power generation technology, but this effort The result is that the unit is huge, the ultra-high voltage is remote transmission, the investment has risen, and the user's integrated energy efficiency is still only about 35, and the large-scale pollution is still not fundamentally resolved.

However, there is a technology that enables energy that has both higher energy utilization efficiency and no contamination environment, which is the fuel cell power generation technology.

Looking at Catherine didn't talk, Baduva thought that Catherine did not understand this technology, and explained: "The energy used by this car is hydrogen energy. The working principle is probably, so that the hydrogen as a fuel is mounted in the fuel cell. The chemical reaction with oxygen in the atmosphere, thereby producing electric energy activation motor, and drives the car. Note that this is a chemical reaction, not directly burning, so Miss Edson, you always want to mute, but also guarantee, This car is the same as the electric car before I have, and the climbing and torque are bigger, you will like it. "

"In addition, methanol, natural gas and gasoline can also be replaced by indirectly extracting hydrogen from these substances. However, this will also produce extremely small carbon dioxide and nitrogen oxides, but in general, such chemical reactions Only water is generated, and it is also very useful in environmental protection. "

After saying these, Baduva grouped by Catherine, then said a little: "Although this technology is supplied, we are inspired by the moon plan, they also use such batteries ..."

Is this this?

Catherine is a little absurd.

"Do you use this technology?"

Catherine somewhat trying, but he hesitated, and then Catherine asked again: "Do you safely do this car?"

"Probably ... is very safe."

probably? !

Also, what is the end of the middle?

"The density of hydrogen is very low, even if the fuel is stored in a hydrogen fuel car low-temperature bottle or compressed gas bottle in a liquid form, it is very limited in those spaces that can be stored."

Catherine turned around and wanted to find the "fuel tank".

"Uh--"

Baduva did not expect Catherine to say the defect of fuel cell cars, I don't know what to say.

He didn't know that Catherine had another worldwide knowledge.

Even Catherine's 21st century, hydrogen cars are very limited than other cars. Some studies have been stored in a higher density environment with special crystals, but safer, but that is not the current technology.

"So what we think now is to use hydrogen recombinant to extract hydrogen from traditional fuel such as methane, gasoline and ethanol. In this case, we can store more"

"Of course, many environmental protection elements are not interested in this idea because it relies on fossil fuels. However, this is a valid recombination process. Use recombinant gasoline or ethanol to promote the fuel cell, still effective than using the internal combustion engine."

Catherine also felt reliable.

"The school district can be used with such a car."

Catherine's words, in the school district, in a sense, it is comparable to the so-called "sacred", heard the sentence of Catherine, Baduva smiled.

"However, we are not there any problem ... manufacturing reliable fuel cells, it is quite high. We are now working hard to study the cost of making fuel cells as much as possible, and this must also guarantee that there is enough hardness to mourning And the basic problem of vibrating these cars ... I am a trial product, but I only dare to open this place in the school district. The design of the fuel cell is mostly fragile, so many times can not be saved. Plus a lot of designs require rare materials such as platinum as accelerator, although the work is more smooth, and the accelerator may contaminate the pureness of hydrogen, which is not conducive to the supply of hydrogen. These studies have been very hard ... "

Baduva shakes his head, it seems that it is quite regret to these studies.

"Hydrogen can be used as an energy carrier rather than energy, you study this, you want to make money, it is early. Hydrogen must be extracted from fossil fuel or other energy, so it will cause energy loss - because of other energy to hydrogen The conversion to energy is not 100% effective, the energy is contest, will you forget? "

Catherine did not hit them.

"Although you have improved, this increased the efficiency of 1 means more than 10, or even more than 20 costs, this is not cost-effective. Calculate someone wants to buy it in cheap, but you may agree?"

"But if it is a hybrid car, you should still come here ..."

Catherine said.

In general, mixing power cars refers to a vehicle that has at least two power sources, using one or more power sources to provide partial or all power vehicles.

However, in the actual research, most of the hybrid vehicles use traditional internal combustion engines and electric motors as power sources, and use thermal energy and power two-set system to start cars. The used internal combustion engine has both a diesel engine and a gasoline engine, so traditional gasoline or diesel can be used, and there is also an engine to use other alternative fuels, such as compressed natural gas, propane and ethanol fuel. Efficiently reinforced motors, generators, and batteries, and the like are included in the electric power system used.

In Catherine, the research funds of vanadium batteries have not yet been in place, but this time has a fuel cell, I can play.

"Hybrid?"

"I need a car, I don't have to be the most handsome, and I don't necessarily have the most wind, but I must be the safest, most comfortable ..."

Catherine is surrounded by the car.

"Those who knew every day, the truck party may be asze, those who are handsome, maybe it is grabbed, or the safest of me ..."

Catherine didn't know the contact in the car was also opened, and Catherine was heard by the general car ...

"Oh, oh. This idea is good, even if you have money, you have to enjoy it!"

Baduva sighed.

"Well ... Do you want three energy, double engine hybrid batteries?"

Three power supplies with gasoline, fuel cells and batteries, Catherine feels that this idea is good.

The maximum power of the internal combustion engine can be determined by the average power of the composite power. At this time, at this time, it works at low fuel consumption and less pollution. When the power of high-power internal power is insufficient, it is supplemented by the battery; when the load is small, the surplus power can generate electricity to the battery. Due to the sustainable work of internal combustion engine, the battery can continue to be charged, so the trip is the same as ordinary cars, and will not decrease .

Moreover, because there is a battery, it can be quickly recovered when the brake is recycled, and the energy at idle speed is when the downhill.

In Catherine, when you need to use high-power, use gasoline, usually use a fuel cell, and then use the battery.

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

"Well, in the investment of vanadium batteries, take a part to invest in fuel cells ... After the technology matures, gasoline what is, it is specifically used as a fuel that produces hydrogen."

Catherine was determined in this way.

......

The third is more complete!

Go to Wudang Mountain tomorrow, hehe.

Tiger touches Xiaochai ^ _ ^
