Yang then met with Sarah Poxon and several Rolls-Royce executives, who also expressed their appreciation for the company's engine design and manufacturing skills.

Yang Jie also laughed at these scenes.

Subsequently, these people also mentioned the fuel cell and motor rotor system products they just saw at the booth of Ruisheng Technology Company, and also put forward the request to visit Huayuan Group Company, a subsidiary of Huaxing Group Company.

Yang Jie naturally agreed, if he could pull Rolls-Royce into the plan of fuel cells as aircraft power source, it would have a huge role in promoting his plan.

On the second day of the public open day, the F100 regional jet produced by Fokker also performed a take-off and landing flight over Le Bourget Airport in front of media reporters from all over the world, which also attracted a lot of attention.

However, airlines are more concerned about the price of Fokker F100 and F70 much lower than similar models, the F100 is only sold for more than 20 million US dollars, while the F70 is only more than 17 million US dollars after discounting, and the price is close to that of turboprop regional airliners.

During the exhibition, there are also many airlines to inquire about the price, after all, the price is there, and the airline is quite sensitive to the price of the aircraft.

Moreover, the good reputation accumulated by Fokker is still there, and it is not so important whether this company belongs to Huaxia or the Netherlands.

Of course, there are also a lot of media that also talk about this matter, attacking Fokker for being assembled in Huaxiaguo, carrying engines produced in Huaxiaguo, and the quality is unreliable, and many of these media are taking the benefits of Boeing and Airbus and Pratt & Whitney, which has also caused a lot of movement.

In this regard, Yang Jie did not have a war of words with these media, Fokker faced these airlines, and Fokker also invited these airlines to visit the assembly line of Huaxia Fokker Company, after all, the wallet is in the hands of these airlines, and meeting the needs of these companies is the most important thing.

The day before the end of the air show, Fokker had already received orders for more than 500 aircraft, and the original order reserve had increased to more than 1,200 aircraft.

This achievement made both Fokker and Huaxia Fokker smile.

In order to deliver the order as soon as possible, Huaxia Fokker Company also proposed to the headquarters to establish two more production lines, and Yang Jie also approved it.

In the evening, Yang Jie also attended the cocktail party held by the Central Plains Provincial Committee of the China Council for the Promotion of International Trade at the Tianhua Hotel in Paris, and also communicated with these Chinese businessmen rooted in France and the officials of the embassy.

Yang Jie was not very interested in such a staggered and ushered in a drinking party, and at nine o'clock in the evening, he also excused himself and left on the pretext that his wife was pregnant and tired.

After he returned to the hotel, he also dealt with some mail, washed up and fell asleep.

Just when he was sleeping in a blur, he was also grateful for a soft body that got into his arms, he subconsciously hugged it, and said in a daze: "Wife, why are you willing to come over tonight?"

The person in his arms was silent, and then he also felt that something was wrong, and opened his eyes, only to realize that Qin Ling had come over secretly.

"Why are you here?" he said in a low voice.

"I'm going back tomorrow, stay with me for a while......"

"Xiaoice is asleep?"

"Well, I wouldn't have come here anyway......"

Holding the warm fragrant nephrite in his arms, Yang Jie also moved his index finger at this time.

"Hmm, don't touch ......"

After a while, there was a heart-warming sound in the bedroom.

For a long time, Yang Jie and Qin Ling were both lazily embracing each other.

After Qin Ling relieved herself, she also groped for clothes to leave, but she was pulled into her arms by Yang Jie, "Stay with me for a while......"

“......”

When Yang Jie woke up again, she found that her surroundings were empty, and she must have sneaked away.

When he was eating breakfast in the morning, Yang Jie saw that Qin Ling deliberately avoided his eyes, but a feeling of guilt welled up in his heart.

After sending Qin Ling away, Yang Jie also felt as if his heart was empty.

A few days later, Yang Jie met with a delegation of Rolls-Royce executives in Tanzhou City.

In the fuel cell production line of Huayuan Group Company, Sara Poxon is also looking at the production line of amorphous carbon coating on the surface of titanium sheet in front of her with great interest.

According to their knowledge, Huaxing's bipolar plates are stamped titanium plates with an amorphous carbon coating on the surface, and the surface coating is prepared by argon plasma cleaning steps and plasma chemical vapor deposition.

Although Huaxing Group has applied for a patent, the gas formula and specific process used in the process of preparing amorphous carbon and forming a certain coating thickness are naturally trade secrets.

Sara Poxon also only knows that these titanium sheets are loaded into a vacuum chamber and the surface is cleaned with argon plasma, which is then formed by a pyridine precursor in a nitrogen-loaded gas environment.

All he knew was that plasma was formed by ionization of an electric field and controlled by a magnetic field, and that the plates were then coated with nitric acid etching and rinsing, which was a complex process.

This set of equipment for the plasma chemical vapor deposition process and etching steps is all provided by Ruixing Technology Company, a subsidiary of Huaxing Group, which also shows the strength of Huaxing Group in semiconductor technology.

The catalyst in the fuel cell stack produced by Huayuan Group is prepared by the Institute of Electrochemistry under Huaxing Group, and most of the patents are also in the hands of the Institute of Electrochemistry.

These catalysts are mixed with slurry in the production line of Huayuan Group, and then the catalytic layer is prepared by special batch groove mold coating, and these catalysts are transferred to the proton exchange membrane, and then the film-forming electrode is prepared by hot pressing with the waterproof gas diffusion layer, and finally assembled into a fuel cell stack with the titanium metal plate modified by the surface.

Rolls-Royce's senior management noticed that a large part of the parts of these fuel cells are provided by subsidiaries of Huaxing Group, the bipolar plates are provided by Chenxi Machinery Factory, the sealing ring is provided by the chemical plant of Zhongyuan Automobile Company, the suppliers of gas diffusion layers are from Japan and Germany, and the proton exchange membrane is used by Gore and DuPont in the United States, and the Institute of Electrochemistry itself also has a proton exchange membrane production line.

The resin for the fuel cell's stack end plates, inlet and outlet pipes, and insulators is provided by Huaxing Semiconductor Materials, a proprietary polyamide material that insulates the aluminum gas distribution manifold from the stack.

Because the high water absorption of the resin will reduce the electrical insulation of the resin material after the temperature rises, the photoresist R&D department of Huaxing Semiconductor Materials has also deliberately added additives to the resin to reduce the conductivity.

The booster and control system outside the fuel cell are independently developed by Huaxing Group, and the IGBT module is provided by Ximenkang.

Sarah Poxon also did a survey before she came, and the electrochemical research institute under Huaxing Group Company has most of the patents for fuel cells, and also has the core technology of catalyst and proton exchange, which can design and develop stacks of all different powers, and only focus on research and development and small batch production, and large-scale production is handed over to Huayuan Group to complete.

Although the fuel cell is also purchased from abroad air compressors, separators, circulation pumps and other components, it will not have much impact on the cost of Huaxing Group.

At present, there are several fuel cell production lines in China, but these companies have been authorized by Huaxing Group Company, and the core components are provided by Huaxing Group.

Although there are many companies that can produce fuel cells, there are no companies that can achieve the performance and cost of fuel cells to the level of Huayuan Group.

Several U.S. fuel cell companies have had to pay royalties and purchase core components to Huaxing for assembly.

For example, BMW Group and Ford Company both purchase fuel cells and motors from Huaxing Group for use in their own automotive products.
