Cage said that there isn't much to prepare, as long as they get the TF, they can do it at any time. I guess it's not too difficult for you technically, right? Zhang Lan asked.

"That's right," Xiao Chenxi nodded, not saving Zhang Lan face at all, "For us, even if we use this very backward fuel cell technology like a big colander on your earth, as long as we have the right research equipment, it is not difficult to quickly break through the cost to a level that ordinary people can accept." ”

Zhang Lan Khan: Girl, although I know what you said, can't you stop saying it so bluntly and save me a little face? In other words, if you say this, as an earthling, I am also very embarrassed on my face.

"That's it," Zhang Lan scratched her head to hide her embarrassment, "In the next two days, let's prepare the relevant materials first, and then contact General Electric of the United States to see what kind of research equipment can be purchased to establish our fuel cell research laboratory." After thinking about it, he added, "If these research equipment is not easy to come up with, it is better to directly set up the research laboratory in the United States, for an American company in the United States, they will never find an excuse not to sell us research equipment." ”

Regarding the ventilation between this project and the country, Zhang Lan did not consider it at all: we don't need your policy support, and we don't need your financial support, so why should we ventilate with you? Zhang Lan naturally knows that the country attaches great importance to the fuel cell project, but Zhang Lan does not want to turn this project into a joint venture project with the state. If you really do this, you won't be able to reap too many benefits if you succeed, and it will all become how the country is doing on this project; If you don't succeed or spend your own money, it's not cost-effective.

"By the way, and. A little," Zhang Lan suddenly remembered that he was ambitious and began to prepare for fuel cells, but the researchers of fuel cells were not yet in place, so he turned to Alice and said, "Sister Alice, please help me talk to those guys who came back from Africa, and ask them, who is willing to stay and help me with this project?" Well, as for the specific number of people, I guess you know better than me, and you have full control over this matter. ”

"No problem, I think too much. Yes, there are always eight out of ten," Alice nodded, pouting disdainfully, "There's no need for more, such a simple thing, so many people are a bit wasteful." ”

Zhang Lan listened. Khan of the brain: This thing that is now being researched by all countries and all high-tech companies in the world, and has been researched for decades, and even a country like China has done research without making much breakthrough, is actually a waste of a dozen people who are simply a dozen people for you? Damn, is there such a big gap between the civilizations on the two planets?

Zhang Lan tried this, but she was still embarrassed to ask, for fear that her self-confidence would be hit by these two girls. However, from the fact that these two girls can invade the national defense system of the United States, which is said to be "the most powerful in the world", as simple and easy as entering their own bedrooms, it seems that the gap between these two civilizations is really not ordinarily large.

"Isn't it necessary to develop a new type of hydrogen. How do you make it? After solving the problems of research projects and researchers, Zhang Lan thought about it, "These fuel cells seem to be fueled by hydrogen, and there are already several clear technologies: the cost of using direct current to electrolyze water to produce hydrogen is too high; At present, the industrial photoelectric hydrolysis of water to produce hydrogen, water gas method, coke oven gas refrigeration hydrogen production, electrolysis of salt water by-product hydrogen, iron and water vapor reaction hydrogen production, and oil thermal cracking syngas and natural gas hydrogen production and other methods are not very ideal, either the cost is too high, or the cost is slightly reduced after the process is too complicated. ”

ZHANG Lan. As he spoke, he said to himself, "It would be nice if there was a simple, convenient and low-cost way to extract hydrogen directly from water." Well, you can also apply for a patent for this technology for producing hydrogen, and you can make a lot of money when the time comes! Remembering that Hou Debang was famous at home and abroad for his "Hou-style alkali production method", Zhang Lan thought beautifully: Can he name this hydrogen production process "Zhang's hydrogen production method"?

"Huh?" Hear Zhang. Arashi said. Surprised, it was Xiao Chenxi and Alice. "Extracted from water. Isn't that the easiest way? Is it difficult? ”

"It's not very difficult. is very costly. Zhang Lan said to the two girls very seriously. You can now check out the process of producing hydrogen from the ground on Earth. Whether it's a simple hydrogen production process or an industrial production process. The costs are all high. He knocked his head with a sad face. It's a headache! The problem of fuel land costs is not solved. It's always a big problem to limit where this stuff can be promoted. ”

Heard Zhang Lan say this. The two girls glanced at each other. The mind has invaded the Internet. Start searching for all relevant hydrogen production sites

Art. It didn't take a while. The two girls looked at each other again. The expression on the face of the little girl began to become more and more weird. Finally, I couldn't help but burst out laughing. Qianqianyu's fingers trembled lightly and pointed at Zhang Lan. Laughing and barely straightening his waist. "Oh my God. Dare to love. It turns out that you use this backward way to produce hydrogen on the earth? ”

"Ugh." Zhang Lan looked annoyed and angry. "Ridiculously?" Then I was stunned again: these two girls are connected." Oh my God," I can say such an exclamation.

"It's not ridiculous. It's felt too. It's fun. "It's so easy. The two girls stopped laughing. "Hmm. Rest assured. Hydrogen is produced directly from water. Well. It's very simple and a little process. This is a trivial question that is not a problem. Title. Let's put it this way. In our opinion. Hydrogen makes this thing. It's the whole fuel cell. The last thing to think about in the research process is the stuff of the earth. Guaranteed to. When it comes to producing a liter of liquid hydrogen, it costs. It will not be higher than the current price of a liter of gasoline. He said. Xiao Chenxi said. "You should know. The amount of energy contained in one liter of liquid hydrogen. But I don't know how many times higher than a liter of gasoline. ”

"Liquid hydrogen?" Hearing Xiao Chenxi's words, Zhang Lan felt dizzy again: it seemed that the temperature of that thing was very low, and it was said that the temperature was about the same as that of liquid nitrogen. ,

"Well, liquid hydrogen is an ideal fuel for fuel cells, and its density is much higher than that of gaseous hydrogen, and liquid hydrogen is much heavier than gaseous hydrogen in the same volume, isn't liquid hydrogen good?" Xiao Chenxi asked rhetorically.

"It's good, although the weight of liquid hydrogen has reached 169 kilograms per cubic meter, and the gaseous hydrogen is only 0.0899 kilograms per cubic meter at a standard atmospheric pressure," Zhang Lan smiled bitterly and seriously recalled the knowledge about hydrogen in his junior high school textbook, "But the requirements for storage of liquid hydrogen are too high. This thing has to be able to maintain the balance of its performance at minus 252.8 degrees Celsius, which is a storage condition, well, not to mention preservation, even if it is very inconvenient to use. Relatively speaking, gaseous hydrogen is more suitable for use, but when the time comes, we will use high-pressure compressed hydrogen similar to a cylinder in the form of a gas tank, so that the density of hydrogen will be larger. ”

The reason why he thought of using cylinders to compress hydrogen was that Zhang Lan suddenly remembered that after the taxi was modified to use natural gas in later generations, it was to use cylinders to compress natural gas, and this method can also be used for hydrogen compression. Using liquid hydrogen? At extremely low temperatures of minus 250 degrees Celsius, the material of the hydrogen supply line alone is a very difficult challenge.

Although liquid hydrogen has a high energy density, I don't expect to use hydrogen fuel in fuel cells in the future. How much trouble would it save them to get them to refuel once a week?

"You have the final say," Xiao Chenxi nodded indifferently, "You understand the usage habits of humans on your earth, and you have the final say on this." ”

Now that the matter has been said here, it would be good to leave the following data collation work and some related preliminary work preparations to Jill, poor Jill has really become the personal assistant of Xiao Chenxi and Alice, the two little girls.

The following things are just waiting quietly, Zhang Lan has been working for a while, and this time she has begun to do nothing: on the afternoon of the first day of the Lunar New Year, Zhang Lan went to worship Mo Liyan, the little girl, uh, I don't know if it is the early or late years, I accompanied this girl crazy for two days, and then I didn't get a break, and I went to Beijing to worship Brother Hu's family for a New Year, and took this opportunity to talk about the future development plan of Alice Group, Zhang Zongjun and Alice gave Brother Hu a reassurance.

Everyone was very happy, the only one who was not very happy was the girl Xiao Nannan, because Zhang Lan stayed in Beijing for too short a time, only three days! God knows, in fact, how can anyone spend the night at someone else's house for New Year's greetings? How much else do you have going on at home? Zhang Lan was able to stay with this girl at Brother Hu's house for three days, which was already the longest time she could squeeze out.

The next step is to return to the company and the various research branches of the Alice Institute of Integrated Applied Science and Technology to start work, and then to carry out a series of test work, including the test of the motorcycle equipped with an all-ceramic engine, and then to arrange the research on the fuel cell and ion battery projects.

It's just that Zhang Lan is still idle now, because he thought of a new and more interesting thing: car HUD, that is, car head-up display. Of course, it's not wrong to call it a "head-up display", this thing is actually the same thing as the thing used on the fighter to display a series of data such as flight parameters, weapon status, aiming attack status, system information, etc., but the actual data is not the data on the fighter.
