Yang Jie and Song Xinyang and others also talked about some things about high-speed trains.

The Ministry of Railways is expected to invest hundreds of billions of dollars in the construction of high-speed railway projects from Yangcheng City to Honghu City, and the Ministry of Railways will invest 50 percent.

"Guanghua Bank can provide a part of the funds. Yang Jie said.

Fu Shaowei said with a smile: "With the participation of Guanghua Bank, it has greatly reduced the pressure on funds. ”

After Yang Jie returned to Tanzhou City, he also rushed to the electrochemical R&D center.

In the laboratory, Yang Jie carefully looked at the newly developed 100 kilowatt third-generation stack on the experimental table, at this time the stack made a low humming sound and was running steadily, and the monitoring screen next to it displayed various data of the stack.

Victor, Yin Zhongping, Chen Xiaojun and others all accompanied Yang Jie.

Yin Zhongping was also reporting to Yang Jie excitedly at this time.

"Yang Shao, we have developed the third generation of reinforced composite proton exchange membrane with directionally oriented proton channels, which can increase the output power of the fuel cell per unit time by 30% compared with the previous proton exchange membrane, and the mechanical and chemical stability has also improved, through testing, this new type of proton exchange membrane can reach 30,000 hours under harsh battery operating conditions. ”

Yin Zhongping has been engaged in the research of proton exchange membranes, and previously worked in DuPont in the United States for more than ten years, resigned the year before last and returned to China, and then joined the Institute of Electrochemistry and became the chief scientist of proton exchange membranes.

The proton exchange membrane prepared by the electrochemistry R&D center was still inferior to the exchange membrane prepared by DuPont and Asahi Glass in terms of chemical and mechanical stability, but it was stronger in structure and conductivity.

After Yin Zhongping joined the team, the overall performance of the proton exchange membrane prepared by Yin Zhongping has been greatly improved, especially in terms of electrical conductivity, which has surpassed DuPont.

Of course, the electrochemistry R&D center has not only made a breakthrough in the proton exchange membrane, but also made progress in the catalyst, through the improvement, the proportion of iridium cobalt alloy used in the catalyst has been reduced to half of the previous one, which also greatly reduces the production cost.

The overall performance of the third-generation fuel cell launched by the electrochemistry R&D center has been greatly improved, the energy conversion efficiency has been increased to 82%, but the volume is 30% smaller than that of the second-generation stack, and the weight has been further reduced due to the application of new materials to the shell, and the energy density ratio has risen to 3.8 kilowatts per liter.

This is already the fuel cell with the highest energy density at this stage, which greatly exceeds the energy density of all fossil energy engines used at this stage.

At the same time, Chen Xiaojun has also made certain progress in the cost and efficiency of hydrogen oil catalysts, and now the electrochemical R&D center has approached the limit of hydrogen storage capacity of unsaturated compounds, and there is little room for improving hydrogen storage, and now the team led by Chen Xiaojun is looking for new compounds.

However, at this stage, the hydrogen storage capacity of 100 liters of hydrogen oil can reach 13 kilograms of hydrogen is already extremely high, which has far exceeded the energy value of fossil energy.

Although the energy value of hydrogen oil with the same weight is half lower than that of fossil fuels, the energy conversion efficiency is 20% higher than that of other engines using fossil fuels when combined with fuel cells and motors, and the price is much cheaper.

Since the unsaturated compounds can be applied all the time, the cost is very low.

In addition, in recent years, Huaxing Group Company has produced various fuel cell products on a large scale, and the production cost of fuel cells has dropped to 30 US dollars per kilowatt.

Now that the electrochemistry R&D center has launched the third-generation fuel cell, Yang Jie is also extremely excited, with such technical strength, the speed of replacing fossil energy engines has become faster.

A few days later, Yang Jie rushed to the test airport where the Hongdu Aviation Group Company in Ganxi Province was located.

In the huge aircraft warehouse, Yang Jie, Laurent of Bombardier Group and others all looked at the fuel cell version of the 200 electric propeller passenger plane quietly parked there in front of them with great interest.

Laurent was also quite excited to climb the high platform and carefully examine the electric propellers hanging under the wings.

The propeller blades are designed and developed by Ruisheng Aviation Technology Co., Ltd., using advanced aerodynamic layout, the propellers have a very beautiful pitch-black luster, and a large number of composite materials are applied.

These blades are curved and swept back, like a saber, with wide and thin plates, a sharp leading edge with a swept back, and this shape resembles the profile of a supersonic wing, with much better transonic performance and good propulsion efficiency at Mach 0.8.

In particular, the low-speed and high-torque permanent magnet motor developed by the Machine Tool Research Institute has achieved a power density of 5 kilowatts per kilogram, and the power of the motor weighs only more than 300 kilograms with other supporting components, which looks very delicate and compact.

"Mr. Yang, I really can't trust you to make the motor so small, but the power is so large. Laurent said with a shocked look on her face.

"Hehe, our company has been developing motors for a long time. Yang Jie smiled and said.

Yang Jie originally dug these experts from Russia in the motor spindle skills are world-class, these years have been on the motor technology continues to carry out research and development, but also from home and abroad to recruit this area of top talents, smashed into the funds do not know how much, now Huaxing group company in the motor technology can be said to be ahead of the international level of at least ten years!

Last year, Bombardier Group gave Huaxing Group a 200 turboprop airliner for upgrading, and Ruisheng Technology also designed new propellers for this airliner, and also added fuel cell systems and electric power systems to the turboprop airliner.

Because the magnitude of the modification is not very large, and a large number of systems are mature skills, the speed is very fast, and the turboprop airliner was modified in less than half a year.

Due to the disagreement between the test flight site of Changhe Aviation Group Company and the suitability of such a passenger aircraft, Yang Jie also directly borrowed the test airport of Hongdu Aviation Group this time.

Laurent then went into the belly of the airliner to inspect the 2,200 kilowatt fuel cell power system installed.

Although this power system is still a mature second-generation fuel cell, it still occupies a small area and does not occupy much space, and the total of the whole system is only one cubic meter of space.

Laurent also nodded frequently at this.

Although the Bombardier Group also sent more than 20 engineers to participate in this reform, they were only responsible for electrical engineering, and they were not involved in fuel cell systems and motor propellers.

Just last week, the reform of this airliner was completed, and Laurent couldn't wait to come over in person.

"Mr. Yang, your speed is so fast, it's really an eye-opener for me!"

Laurent looked at Yang Jie and said, "Can you arrange the test flight tomorrow?"

"Of course there is no problem. Yang Jie nodded.

On the morning of the next day, the 200 was slowly towed out of the grand aircraft warehouse under the tow of a tractor, and then towed to the tarmac next to the airport runway.

The tarmac was also full of people at this time, in addition to cover, ground staff, test pilots, etc., the Xifei Aviation Group Company and the military also came.

"Wow, what kind of plane is that?"

"This is a 200 turboprop regional airliner produced by Bombardier Airlines, but it has now been transformed into an electric propeller and fuel cell airliner by Huaxing Group. ”

"Wow, look at the motor under the wing, is that so small, can this push this airliner?"

"You're too worried, I went to Ruisheng Technology Company to see the motor they assembled, don't look small, the torque generated is amazing!"

"The technical strength of Huaxing Group Company is really strong!"

"yes, it's the first time I've seen a company use an electric motor as a turboshaft engine!"

……

Hearing the discussion of these people next to him, the smile on Yang Jie's face became even bigger.
