Great Country Academician

Staying in front of the platform, Xu Chuan looked at the battery technology displayed by the unknown company in front of him with some interest.

Hydrogen fuel cell.

This is almost one of the very few battery products that still have great potential for development among various types of batteries after the lithium dendrite problem is solved.

Beside the booth, those who were publicly displaying their products quickly noticed Xu Chuan and Fan Pengyue standing in front of them.

"Hello, do you two gentlemen want to know more about our products?"

The commentator with a sweet smile walked over quickly, looked at Xu Chuan and said, "This is our company's latest battery product, a diaphragm liquid hydrogen storage fuel cell. Its battery energy density can reach a high energy storage of 40kWh per kilogram. Hundreds of times more powerful than traditional lithium-ion batteries."

"Energy density of 40KWh per kilogram? Are you sure your decimal point is correct?"

Listening to the commentator's narration, Xu Chuan interrupted her and asked curiously.

This explainer is indeed good-looking, but his explanation of the product can only be described as scripted and emotionless. Probably the commentator specially invited by this company or the company's front desk was caught.

"Yes, sir. This is our latest diaphragm-type liquid hydrogen storage fuel cell. The theoretical energy density can indeed reach this value."

Xu Chuan smiled and said, "Do you have product information? Can you give me one?"

Theoretically speaking, the energy density of hydrogen can still reach 20,000Wh/Kg.

In the face of this value, not to mention lithium-sulfur batteries, even lithium-air batteries are not enough.

But to reach the theoretical value of 20,000Wh/Kg, we probably have to achieve the legendary solid hydrogen.

At present, this can be said to be a concept that only exists in theory and does not even exist in the laboratory.

"Okay, sir. Please come with me. There are seats in our booth. You can sit down first and I will go get the information for you."

With a standard smile, the commentator introduced the two people to the booth.

Although I feel that the young man in front of me may not be like a 'boss' who can bring business and cooperation to the company, but looking at the handsome face of the young man in the lead, it's okay to have nothing to do anyway and just chat.

It had been all morning, and there were not many people paying attention to their hydrogen fuel cells. If it weren't for the regulations, she would have been sitting there playing with her mobile phone.

At this time, the company manager sitting in the booth also noticed the two people walking in.

Everyone who came was a customer. The middle-aged manager stood up quickly, buttoned up his suit and walked over. When he was about to say hello with a smile, he was stunned when he saw Xu Chuan.

After a while, he finally came to his senses and asked tentatively in surprise: "Are you Academician Xu Chuanxu?"

As a person who often surfs the Internet and as a researcher working on batteries, how could he forget this handsome face.

But what he couldn't believe was that the famous Academician Xu would actually appear here, and he couldn't believe that he would be interested in the hydrogen fuel cell developed by his company.

Xu Chuan smiled, nodded, and replied, "That's right."

After hearing the affirmative answer, Ji Lixue, the middle-aged manager of Tomorrow Company, his eyes lit up. He stepped forward in three steps and two steps at a time. He stretched out his hands with great enthusiasm, and his face was full of smiles.

"Hello, Academician Xu. It's a great honor to meet you here. Please take a seat. I'm Ji Lixue, the business manager of Tomorrow Hydrogen Energy Company. You can just call me Xiao Ji."

"cough"

Looking at Ji Lixue's face, which was almost forty, Xu Chuan couldn't help but cough lightly. This made Xiao Ji unable to stop screaming.

"Hello, Manager Ji, I am interested in the hydrogen fuel cell launched by your company. Can you introduce it to me?"

Hearing Xu Chuan's words, a trace of embarrassment flashed across Ji Lixue's face, and he forced a smile and said: "Of course there is no problem, but please forgive me, Academician Xu, our company's product is only a semi-finished product and has not been commercialized yet. standard."

Playing tricks, he bumped into this real boss in the battery field, which made him very embarrassed and uneasy.

Xu Chuan smiled and said, "It's okay, I just took a look."

Ji Lixue nodded, quickly took the computer from the explainer who went to get the information, and came to explain his company's products to Xu Chuan in person.

Diaphragm liquid hydrogen storage fuel cells are a technology they started researching four or five years ago.

At that time, the artificial SEI thin film technology researched by Xu Chuan appeared, and many companies in the battery field were studying lithium batteries. If it were not for Tomorrow's hydrogen energy company, it would be based on 'hydrogen' and would not have any foundation in the field of lithium batteries. It will probably transform as well.

They have no choice but to bite the bullet and continue to try to advance on the road of hydrogen fuel cells. But it is obvious that with the booming development of lithium-ion batteries, the market occupied by hydrogen fuel cells is being rapidly compressed.

If the company had not had some channels with the government and could obtain some orders for hydrogen buses and hydrogen taxis, it would have been unable to survive long ago.

But it is obvious that as the company's revenue decreases, there is less and less funding for hydrogen fuel cell research and development.

Diaphragm liquid hydrogen storage fuel cell, this is probably their last hydrogen fuel cell.

It took four or five years to produce a semi-finished product. If there is no investment at this Asia-Pacific Science and Technology Innovation Investment Summit, Tomorrow's company will probably be completely dead.

On the side, the commentator lady who had been robbed of her business by the leader was a little resentful and looked at Manager Ji Lixue who was bending down in front of Xu Chuan with a dissatisfied look on her face.

Finally, a handsome young customer brother came here. This manager has no moral ethics!

But before she could recover, a statement from Ji Lili's mouth immediately shocked her.

"Academician Xu, you see, this is the core key of our diaphragm liquid hydrogen storage fuel cell. Passed"

The explanation sound rang in the ears, and the lady commentator suddenly froze with a resentful expression, her mouth opened in a circle, and she looked at the customers who were sitting there enjoying the service of her own manager with an incredulous look on her face.

"Academician Xu Xu?"

Blinking her eyes, she looked shocked in disbelief. The legendary God of Sichuan?

Damn it! I actually received Sichuan God in person? ! ! !

Beside the booth, Xu Chuan didn't pay attention to the shock on other people's faces. He looked with interest at the hydrogen fuel cell designed and manufactured by the Tomorrow Hydrogen Energy Company in front of him.

Hydrogen fuel cells are quite different from traditional charge-discharge batteries\\

Traditional dry batteries and batteries are energy storage devices that store electrical energy and release it when needed;

Strictly speaking, a hydrogen fuel cell is a power generation device. Like a power plant, it is an electrochemical power generation device that directly converts chemical energy into electrical energy.

It can directly convert the chemical energy of hydrogen and oxygen into electrical energy. Its basic principle is the reverse reaction of electrolyzing water. Hydrogen and oxygen are supplied to the anode and cathode respectively. After hydrogen diffuses outward through the anode and reacts with the electrolyte, electrons are released and reach the cathode through an external load.

Because the mass of hydrogen is small, but hydrogen and oxygen have high efficiency, quiet operation, and no pollution, which are clean energy characteristics, the prospects of hydrogen fuel cells are still quite good.

Although the conversion properties of fuel cells can directly convert chemical energy into electrical energy, there is no need to go through the intermediate conversion of thermal energy and mechanical energy (generator).

But compared with lithium batteries, its power generation efficiency or conversion rate is still slightly lower. Current technology can reach about 50%-60%, which is lower than the efficiency of lithium batteries, which is about 75%.

However, hydrogen has the properties of fuel, and the replenishment speed is faster than the charging of lithium batteries.

The core of the research results of this tomorrow's hydrogen energy company lies in the 'separator' in the hydrogen-oxygen battery.

The diaphragm, also called an exchange membrane in a hydrogen-oxygen fuel cell, plays an important role in isolating the anode and cathode and transmitting protons.

Traditional exchange membranes have problems such as poor durability and poor chemical corrosion resistance, which limit the long-term stable operation of hydrogen fuel cells.

The team of Tomorrow Hydrogen Energy Company reconstructed the cell structure of proton exchange membrane fuel and introduced ultra-thin carbon nanofiber films and nickel foam made by electrospinning technology, removing the traditional gas diffusion layer and groove-ridge flow. road.

After integrating this new set of components, this new hydrogen-oxygen fuel cell effectively reduces the thickness of the membrane electrode assembly by about 90%, reduces the mass transfer loss caused by reactant diffusion by more than 80%, and successfully combines the fuel cell The volumetric power density is increased by approximately two times.

This is why the title of the energy density of one kilogram of hydrogen batteries is 40kWh on the exhibition stand.

But the slogan is only theoretical. In fact, this hydrogen-oxygen fuel cell is far from the 40kWh energy density.

Judging from the current 'internal' data revealed by Manager Ji himself, the capacity density of this hydrogen-oxygen battery is actually less than 1KWh per kilogram.

Forty times the gap, this slogan is indeed loud enough.

Standing aside, Ji Lixiu's forehead was almost dripping with cold sweat.

Business, isn't it just about bragging?

But who would have thought that the cake they drew would actually hit the boss's head and get his attention.

This is a real 'academic' level expert. If you are a little dissatisfied with their behavior, just say a casual word, and the collapse of the hydrogen energy company tomorrow will really happen tomorrow.

On the seat, Xu Chuan was flipping through the information in his hand, but he didn't pay much attention to Ji Lixiu's expression beside him.

After staring at the newly developed proton exchange membrane fuel information for a while, he raised his head and asked: "Manager Ji, do you lack investment in this hydrogen-oxygen fuel cell?"

Standing aside, Ji Lili was stunned.

He stared at Xu Chuan blankly, motionless, feeling as if he was hallucinating.

Seeing that there was no movement from the other party, Xu Chuan thought for a moment and then asked in a different way: "Does your company still lack investment?"

Hearing the question again, Ji Li suddenly shuddered, quickly came to his senses, and said quickly: "Que, Que, even if I sell the entire company to you, there is no problem at all."

If a regular business manager said this, he would naturally be overly concerned.

However, he also holds a stake in Tomorrow's Hydrogen Energy, and his shareholding is quite large, reaching 38%, so he is fully qualified to say this.

Ji Lixue's heart was pounding. He knew very well that if the person in front of him said he wanted to invest in Tomorrow's Hydrogen Energy, then Tomorrow's Hydrogen Energy might be able to expand to next year, no, it could be directly listed this year.

It's still half-dead like now.

This opportunity, this piece of pie, simply fell directly into his mouth from the sky.

At this moment, someone suddenly made a sound among the crowd that had gathered around him.

"Manager Ji, we at Matrix Partners are willing to invest in your hydrogen fuel cell!"

In the crowd, a middle-aged man in a suit raised his hand and stared eagerly here. To be precise, it fell on Xu Chuan who was sitting there.

It was obvious that he had recognized it.

Following the call from Jingwei Venture Capital to follow suit, other people surrounding the booth quickly responded.

"Mr. Ji, we at CITIC Group are willing to invest five million! The hydrogen fuel cell project is okay. We at CITIC Group can help you contact banks for loans in the future, with ultra-low interest rates!"

"Manager Ji, our Gaoge Venture Capital is willing to invest 5 million in the hydrogen fuel cell project! As long as 10% of the equity is enough! I checked, the total value of Tomorrow Hydrogen Energy Company is less than 50 million, and one project is 100% 10% of the equity is definitely enough!”

"Five million is too little. Mr. Liu, you are a bit bold. The hydrogen fuel cell situation is very good. Our Innovation Group is willing to invest 20 million! As long as we have equity and dividends, we can guarantee that we will not interfere with the company's internal management!"

"We, Starlight Venture Capital, are willing to invest five million! We, Starlight, have enough connections in the automotive industry and can help you contact more car companies to promote and install your hydrogen fuel cells! All we need is that you give up some equity That’s it!”

"I, Pei Qian, voted for this project!"

"."

In the crowd, noisy follow-up calls continued to sound.

If the organizer's security had not noticed the situation before and brought people over in time to maintain order, these crazy people would have crowded into the infield.

In this way, people kept coming from other places, and there were also people in the crowd who kept sending messages or making phone calls, asking their bosses to come over quickly.

The people who maintained order were already stupid. Even those who had witnessed many big scenes at the Shanghai International Convention Center were shocked by this. This was the first time he had seen such an exaggerated formation.

The leader of the security team on the seventh floor, who maintained order, quickly called for support through the pager and controlled the crowd that was crazily pushing inward.

At the same time, not only the security personnel maintaining order were confused, but also Ji Lixue, who was standing there, was completely confused.

To be honest, when he attended the Asia-Pacific Science and Technology Innovation Investment Summit, he was actually prepared to lose everything.

After all, lithium-sulfur batteries are already available, so who cares about your unfinished hydrogen fuel cell?

Unexpectedly, a sudden turn of events took place, and one after another investment companies seemed to throw money at him as if they didn't regard money as numbers.

The key to all this is just that the person sitting here is optimistic about their hydrogen fuel cell.
