Submarines? Zhang Lan muttered. That's a good thing.

"What?. Xiao Chenxi was stunned for a moment, and subconsciously asked, "China is ready to let us participate in the research and development of submarines?"

Can a private enterprise with Sino-foreign joint ventures also participate in the research and development of submarines, a weapon that has a bearing on national strategic security? Not only Xiao Chenxi and Alice, but even Zhang Lan couldn't believe what she had heard: too exaggerated, right?

"Of course, what's wrong with that?" Zhang Dingjun, who had already guessed why this girl was so surprised, was very satisfied with Xiao Chenxi's reaction, and asked with a smile, "In terms of qualifications, you now have the qualifications to develop countless weapons and equipment; In terms of technology, it seems that your company's fuel cell technology is frowned upon by Japanese, Europeans and Americans; In terms of technical team, probably, no one hums a complete R&D team, you are not qualified, who has this qualification? ”

Well, add to that the good relationship between you and the upper echelons.

After finishing speaking, Zhang Dingjun added in his heart, if it weren't for the good relationship between the Alice Group and the upper echelons, if it was any company with the same technical strength as the Alice Group, it would be impossible for the country to cooperate with them, in other words, the bigwigs above believe that the risk of cooperating with the Alice Group is quite this trust, which has been accumulated little by little by the Alice Group over the years.

"That is". Zhang Lan nodded: his fuel cell is the most advanced, there is no doubt about this! For this, Zhang Lan is full of confidence.

If you remember correctly, the research on postal technology has already begun in China, right? It seems that a small experiment has already begun, but as a military secret, I am naturally not qualified to know, but I only know that in the years after entering the new century. The domestic navy used the phrase "Song." The submarines of the class conducted several experiments on alcoholic technology.

As one of the world's three major postal technologies, it seems that the most realistic fuel cell mail technology is the most likely to be popularized, and Germany is developing and manufacturing, and will be equipped with their navy's Yin-2 fuel cell diesel-electric hybrid submarine is a typical representative of this, and the Yin-2 submarine is equipped with a field-type fuel cell stack with an output power of more than four kilowatts, which has also become the object of the eyes of the navies of various countries in the world.

There is no way, the advantages of fuel cells are too many, otherwise it is impossible for the military and civilians of all countries in the world to study the driving method powered by fuel cells, and now it is impossible to set off this automobile power revolution with the wave of fuel cell vehicle research and development in the world.

And for the militaries of all countries in the world, especially the navy, the temptation of fuel cells makes them feel like they have seen a big bad wolf with a lamb after being hungry for half a month, and their saliva is raging!

"Huh? You know this? Zhang Dingjun Yan Ran was greatly surprised by Zhang Lan's reaction.

He didn't expect that Zhang Lan, this kid, would actually know the so-called qu technique, this guy actually said it to Alice, but he didn't expect that Zhang Lan, this kid, seemed to be thoughtful. It's weird, how did he know? Although the English word is derived from their company's fuel cell technology.

Zhang Lan almost fainted: As the owner of a fuel cell company, a military enthusiast and the owner of an automobile company, it is impossible not to know what is the hottest energy research and development direction in the world, right? Not to mention that there is also a role behind this hot topic.

"Isn't that difficult?" Zhang Lan was a little crying and laughing, "The energy conversion efficiency of fuel cells is high, because the efficiency of fuel cells is not limited by the Carnot cycle, and under the premise of using hydrogen and oxygen energy, the energy conversion efficiency of the internationally advanced level of field-based fuel cell stacks has reached the level of "Well, what else?" Zhang Dingjun was a little surprised in his heart: This kid knows a lot?! However, thinking of this kid's family's industry and the reason why they came over this time, I couldn't help but secretly blame myself for being rare and weird, why did I think this kid was a child of an ordinary family?

"There are many advantages" Zhang Lan was also happy to show off his company's technical strength by the way, and introduced it to Zhang Dingjun with his fingers like a few treasures, "Even if methanol is used as fuel, its energy conversion efficiency can also be reached, but as another direction of four-port technology development, the efficiency of the Stirling engine is only Maca, and the efficiency of closed-cycle diesel engines is even worse, less than that of Maca, and they must convert mechanical energy into electrical energy before they can make the propulsion motor run." The energy conversion efficiency of fuel cells is incomparable to that of the current submarine internal combustion engine and the other two four-port technologies. ”

The most direct effect of high energy conversion efficiency is that the oxygen consumption of fuel cells is only half that of other power gastrics. The longer the submarine is required to be hydraulically powered, the more obvious the superiority of the fuel cell's high efficiency becomes, and if possible, the admirals even want the submarines to remain underwater all the time.

As the commander of the Navy, Zhang Dingjun naturally understands the significance of this, and Zhang Dingjun's understanding of the existing closed-cycle diesel engine (Qu, Stirling engine (raw) and fuel cell (ratio) such as three four-port technologies is definitely an expert-level figure in the domestic military leadership. What Zhang Lan didn't know was that Zhang Dingjun was one of the main figures in the domestic military's promotion of the four submarine technologies.

In fact, there is also a four-port technology, namely: underwater energy cabin) four technology, but it has been proved that the underwater energy cabin (female) four technology has too many technical shortcomings compared with the other three such as technology, and now this kind of Han technology has been recognized as one of the four such as the most unrealized value, so it is usually speaking. Generally speaking, it is just said that there are three kinds of four technologies.

"What are the advantages of fuel cell technology?" Zhang Dingjun asked with interest.

If the previous question was still a bit of a joke, then Zhang Dingjun's inquiry this time has some exquisite factors in it, and it is also an opportunity for Zhang Dingjun to understand the strength of Alice Group in fuel cell technology from the side: If a little guy like Zhang Lan will have a deep understanding of technology, wouldn't it also prove that Alice Group is one of the best partners of the military in the four technologies? ,

In addition, the noise of fuel cell power is very large because the fuel cell itself has no moving parts, can operate in a completely silent state, and only the micro-circulating mercury in the auxiliary system will emit a low noise, which is simply the biggest boon for submarines with high requirements for quietness: think of the deterrent ability of the Kilo-class submarines known as the "black hole of the ocean" against the US aircraft carrier group.

Zhang Lan didn't care about Zhang Dingjun's little psychology, for a military hobby, it is very painful to not have someone who can communicate with him at the same level, if this, the guy has a military person who can communicate, it is undoubtedly a very happy thing, and if this guy who can communicate with himself is a senior general of the military, well, it is estimated that it can make people want to faint happily, so this kid is now starting to drink endlessly:

"In addition, the reaction product of the fuel cell is water, so it does not require a post-treatment system compared to other curved technologies and structures. Because the working products of various heat engines have carbon dioxide and other exhaust gases, if these carbon dioxide and other exhaust gases are directly discharged from the boat, the primary factor is that it will definitely consume power and will produce tracks, and if it is not handled well, it is easy to produce a large number of bubbles, which will seriously affect the concealment of the submarine, which is quite fatal to the submarine that needs to hide in the dark to attack others. ”

Zhang Dingjun nodded, this kid is right, the biggest threat to the submarine is his concealment, if concealment becomes a problem, then others are still afraid of a fart!

Now there is no need for Zhang Dingjun to stimulate, Zhang Lan, this kid himself has already said that he is addicted, and he talked endlessly at Zhang Dingjun, foaming at the mouth, "If it is absorbed with chemicals, such as alkali lime or other chemicals, it will inevitably increase the weight and volume of this system, which is very uncost-effective for submarines that have to be carefully calculated without a little weight and volume." But the fuel cell does not have these problems, the fuel cell reaction product is water, which can be left in the boat, or discharged out of the boat, and the treatment method is much simpler. ”

Zhang Dingjun chuckled, of course he understood the ridicule in Zhang Lan's words, for submariners, the lack of water is a very troublesome thing, although they sail in the water all day long, but the fresh water that can be used is very small, when sailing, the fresh water on the boat is particularly precious, and even the faucet of the submarine has a special management.

That's it, in addition to the drinking water necessary for daily use, the water used for washing and makeup every day is pitiful, and it is directly measured in a tea jar, washing their faces and brushing their teeth. Some experienced veterans will secretly bring plastic buckets full of water to the boat before the voyage, which is really dirty and uncomfortable, so that they can use it for personal hygiene.

Zhang Dingjun was very sure in his heart that if the submarine was equipped with a mail system, water, the product of hydrogen-oxygen reaction, could really become a very good daily water for the officers and men on the submarine, and if the water quality was high, it would not be impossible to drink it directly.
