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 cells.

This is almost after the solution of the lithium dendrite problem, among the current various types of batteries, there are very few battery products with great potential for development.

Next to the booth, the people who publicly displayed their products quickly noticed Xu Chuan and Fan Pengyue who stayed in front of them.

"Hello, do you 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, diaphragm liquid hydrogen storage fuel cell, whose battery energy density can reach 40kWh per kilogram of high energy storage, which is hundreds of times that of traditional lithium-ion batteries."

"Energy density per kilogram of 40KWh? Are you sure your decimal point is not marked with a wrong mark? ”

Listening to the narrator's narration, Xu Chuan interrupted her words and asked with some curiosity.

This commentator's appearance is indeed good, but the explanation of the product can only be said to be based on the script, without emotion. Probably the docent specially invited by this company or the front desk of the company was arrested.

"Yes, sir. This is our latest diaphragm liquid hydrogen storage fuel cell, and the theoretical energy density can indeed reach this value. ”

Xu Chuan smiled and said, "Do you have any product information?" Can you give me a copy? ”

Theoretically, theoretically speaking, the energy density of hydrogen can reach 20,000Wh/kg.

In front 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, it is probably necessary to achieve the legendary solid hydrogen.

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

"Yes, sir. Please come with me, there are seats in our booth, you can sit down first, and I will go and get you information. ”

With a standard smile, the docent ushered the two into the booth.

Although I feel that the young person in front of me may not look like a 'boss' who can bring business and cooperation to the company, but for the sake of the handsome appearance of the young man in the lead, it is okay to be idle anyway, and it is good to chat.

It's been a morning, and there are few people who take care of their hydrogen fuel cells, and if it weren't for the regulations, she would have been sitting and playing with her phone.

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

Everyone who came was a guest, and the middle-aged manager quickly stood up, put on the buttons of his suit and walked over, and when he was about to say hello with a smile, he was stunned when he saw Xu Chuan.

After half a sound, he reacted and asked tentatively in surprise, "Are you. Academician Xu Chuanxu? ”

This handsome face, as a person who often surfs the Internet, as a researcher engaged in batteries, how could he forget.

However, he couldn't believe that the famous academician Xu would appear here, and he couldn't believe that he would be interested in the hydrogen fuel cell developed by his own company.

Xu Chuan nodded with a smile and replied, "It's exactly below." ”

After hearing the affirmative answer, Ji Lili, the middle-aged manager of Tomorrow's company, lit up, stepped forward in three steps and two steps, and stretched out his hands enthusiastically, with a smile on his face.

"Academician Xu, hello, it's an honor to meet you here, please take a seat, I'm Ji Lili, the business manager of Tomorrow's Hydrogen Energy Company, you can just call me Xiao Ji."

"Ahem"

Looking at Ji Li's face that was almost forty, Xu Chuan couldn't help coughing lightly, this Xiao Ji couldn't scream.

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

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

The class got an axe and bumped into this real big guy in the battery field, which made him very embarrassed and worried.

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

Ji Li nodded, quickly took over the computer from the commentator who went to get the information, and personally explained his company's products to Xu Chuan.

Diaphragm liquid hydrogen fuel cell is a technology they started working on four or five years ago.

At that time, Xu Chuan's artificial SEI thin film technology appeared, and many companies in the battery field were studying lithium batteries.

They had no choice but to bite the bullet and continue to try to continue to push forward on the road of hydrogen fuel cells. However, it is clear that with the vigorous development of lithium-ion batteries, the market occupied by hydrogen fuel cells is being rapidly compressed.

If the company hadn't had some channels on the government side and could get some orders for hydrogen buses and hydrogen taxis, it would have been unable to sustain itself.

However, it is clear that along with the decline in the company's revenue, the amount of money spent on hydrogen fuel cell research and development is decreasing.

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

It took four or five years to make a semi-finished product, and if it can't get investment at this Asia-Pacific Science and Technology Innovation Investment Summit, the company will probably die completely tomorrow.

On the side, the young lady of the commentator who was robbed of the business by the leader was a little resentful, and looked at Manager Ji Lili who was bent down in front of Xu Chuan with a dissatisfied face.

Finally, a handsome young customer little brother came, this manager doesn't talk about martial arts!

But before she came back to her senses, she was directly stunned by the statement from Ji Li's mouth.

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

The sound of explanation sounded in her ears, and the resentful expression of the narrator's young lady was suddenly stunned, her mouth opened into a circle, and she looked at the customer who was sitting there enjoying the service of her manager with an incredible face.

"Academician Xu Xu?"

Blinking her eyes, she looked shocked in disbelief, that legendary Sichuan god?

it! I actually received Kawajin in person?!!!

Next to the booth, Xu Chuan didn't care about the shock on the faces of others, he looked at the hydrogen fuel cell designed and manufactured by the hydrogen energy company in front of him with interest.

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

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

Whereas, a hydrogen fuel cell is strictly a power generation device, like a power plant, an electrochemical power generation device that converts chemical energy directly into electrical energy.

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

Because the mass of hydrogen is small, but the characteristics of hydrogen and oxygen efficiency, quiet operation, and pollution-free belong to clean energy, the prospect of hydrogen fuel cells is 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 an intermediate conversion of thermal energy and mechanical energy (generator).

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

However, hydrogen has the properties of a fuel, and it can be replenished faster than 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 separator, also known as the exchange membrane in hydrogen-oxygen fuel cells, plays an important role in separating the anode and cathode and transferring 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 battery structure of proton exchange membrane fuel, and removed the traditional gas diffusion layer and groove flow channel by introducing ultra-thin carbon nanofiber films and nickel foam made of electrospinning technology.

After integrating this new set of components, the new hydrogen-oxygen fuel cell effectively reduces the thickness of the MEA assembly by about 90%, reduces the mass transfer loss caused by reactant diffusion by more than 80%, and successfully increases the volume power density of the fuel cell by about two times.

This is where the title of the value of a kilogram of hydrogen battery energy density of 40 kWh was put on the booth.

It's just that the slogan is only theoretical, and in fact this hydrogen-oxygen fuel cell is far from the energy density of 40 kWh.

Judging from the 'internal' data that the current manager Ji personally broke out, the capacity density of this hydrogen-oxygen battery is actually less than 1KWh per kilogram.

Forty times the difference, this slogan, shouted loudly enough.

Standing aside, the cold sweat on Ji Li's forehead was about to flow out.

Isn't business originally a boast of painting cakes?

It's just that who would have thought that the cake they painted would hit the big guy's head, and he paid attention to it.

If you are a little dissatisfied with their behavior, casually say a word, the collapse of tomorrow's hydrogen energy company will really be tomorrow.

On the seat, Xu Chuan flipped through the information in his hand, but he didn't pay much attention to Ji Li's expression on the side.

After staring at the newly developed proton exchange membrane fuel information for a while, he raised his head and asked, "Manager Ji, is there a lack of investment in your hydrogen and oxygen fuel cell?" ”

Standing aside, Ji Li's whole person was directly stunned.

He looked at Xu Chuan in a daze, motionless, feeling as if he was hallucinating.

Seeing that the other party did not move, Xu Chuan thought for a while, and asked in a different way: "Is your company still short of investment?" ”

Hearing the sound of inquiry again, Ji Li's whole person shuddered, quickly came back to his senses, and hurriedly said: "Lack, short, even if the whole company sells it to you, it's all fine." ”

If the regular business manager says this, it will naturally be more and more sprouts.

However, he also owns the shares of Tomorrow's hydrogen energy, and the number of shares is not small, reaching 38%, and he is fully qualified to say this.

Ji Lili's heart was pounding, he knew very well that if the person in front of him said that he wanted to invest in tomorrow's hydrogen energy, then tomorrow's hydrogen energy might be able to expand to next year, no, it would be directly listed this year.

Where is it still the same half-dead as it is now.

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

At this moment, in the crowd that gathered around at an unknown time, someone suddenly spoke up.

"Manager Ji, your hydrogen fuel cell, we are willing to invest in Jingwei Venture Capital together!"

In the crowd, a middle-aged man in a suit and leather shoes raised his hand, his eyes staring eagerly at this side, to be precise, it fell on Xu Chuan, who was sitting there.

Apparently, he had recognized it.

And with the sound of Jingwei Venture Capital, other people around this booth quickly reacted.

"Mr. Ji, we CITIC Group are willing to invest five million! The hydrogen fuel cell project is okay, and we CITIC Group can help you contact the bank for a loan in the future, with ultra-low interest! ”

"Manager Ji, we are willing to invest five million in the hydrogen fuel cell project! All you need is 10% equity! I have checked, the total value of tomorrow's hydrogen energy company is less than 50 million, and 10% of the equity of a project is definitely enough! ”

"Five million is too little, Mr. Liu's courage is a little small, the hydrogen fuel cell scenario is very good, our innovation group is willing to invest 20 million! As long as the equity and dividends, it can be guaranteed that it will not interfere in the internal management of the company! ”

"We at Starlight Ventures are willing to invest 5 million! We have enough network in the automotive industry to help you connect with more car companies to promote and install your hydrogen fuel cells! All you need to do is give up some of your equity! ”

"This project, I Pei Qian voted!"

“.”

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

If it weren't for the security of the organizer who noticed the situation here before and brought people over in time to maintain order, I'm afraid these crazy people would have squeezed into the infield.

In this way, there are still people rushing over from other places, and there are also people in the crowd constantly sending messages or making phone calls, asking their bosses to hurry over.

The people who maintain order are already stupid, even if they have seen a lot of big scenes at the Modu International Conference Center, they will be shocked. It was the first time he had seen such an exaggerated battle.

The leader of the security team on the seventh floor, who was maintaining order, hurriedly called for support through the pager and controlled the crowd that was frantically squeezing inward.

At the same time, not only the security personnel who maintained order were stunned, but even Ji Li, who was standing there, was also completely confused.

To be honest, when he participated in this Asia-Pacific Science and Technology Innovation Investment Summit, he was actually ready to receive nothing.

After all, lithium-sulfur batteries are all on the market, and who cares about your unfinished hydrogen fuel cell.

Unexpectedly, one after another, investment companies smashed money on his head as if they didn't treat money as a number.

And the key to all of this is simply that the guy sitting here is bullish on their hydrogen fuel cells.
