Although this cost is higher than the investment in thermal power plants, it is already very remarkable that the electrochemistry laboratory can now reduce the cost to the current level, and the cost of hydrogen and oxygen fuel cells of the same power in foreign countries is more than 70,000 US dollars, which is very expensive.

The life test of the first generation of stacks has now been completed, the life of the proton exchange membrane can reach 15,000 hours, the life of the catalyst is also 10,000 hours, the overall design of the second generation of stack proton exchange membrane and catalyst and solid electrolytic solute and stack have all been improved, and now from the test results, especially the energy density has been increased by more than two times, and there has been a lot of improvement in all aspects, and now several types of stacks are running smoothly.

By the time the second-generation stack completes various tests, it will be almost 02 years, and when the third-generation fuel cell comes out, it should be able to be installed on the car for small batch testing.

However, the technology of the second generation of stacks can now be used to test in power stations and buses.

Although the current first-generation hydrogen storage tank can only reach 35 megapascals, the space of the bus is relatively large, and when the time comes, it can solve the technical problem of insufficient mileage by carrying several more hydrogen storage tanks.

In the evening, Yang Jie also came to Li Kaiyuan's residence and told him about the major breakthrough made in the fuel cell stack.

"Uncle Li, in order to reduce the cost of hydrogen production, I suggest that the provincial coal company can now introduce a coal-to-hydrogen production line. Yang Jie said: "The coal reserves and production of Central Plains Province are good, especially our country is very rich in coal resources, if the development of coal-to-hydrogen industry then our country has a natural advantage, and the cost of coal-to-hydrogen is lower than the cost of caustic soda and refineries." ”

Li Kaiyuan nodded with a smile: "Now there is no coal-to-hydrogen production line in China, and our Central Plains Province must take the lead and cooperate with the fuel cell industry of your Huaxing Technology Group." Tomorrow, I will ask the Provincial Coal Industry Bureau to start the project approval of the coal-to-hydrogen project, and strive to start construction as soon as possible. ”

"Uncle Li, through the research and development of the electrochemical laboratory, it is also found that our domestic technical strength in the circulation compressor is very weak, now there is no way to produce 35 megapascal circulating compressor in China, our design goal is to be able to reach 70 megapascal hydrogen storage tank, and now the top foreign American PDC company can only produce 40 megapascal compressors, so I also plan to let the company look for engineering and technical personnel in this area to develop metal diaphragm compressors to meet our requirements. ”

"Do you need a compressor with such a high pressure output?" Li Kaiyuan's eyes widened.

"Only by reaching such a high air pressure can we fill more hydrogen in the high-pressure gas tank, we have calculated that according to the volume of the car, the maximum capacity of 120 liters of gas tank, only 70 megapascals can store 5 kilograms of hydrogen, and the mileage that can be driven by a single hydrogen filling can exceed that of a gasoline car. ”

Yang Jie said: "Because the permeability of hydrogen is very strong, it must be pressurized with a metal diaphragm compressor, and this compressor can not only compress hydrogen, but also suitable for compressing high-purity, rare and valuable, flammable and explosive, toxic and harmful, corrosive and high-pressure gases, suitable for the transportation and pressurization of various gases, and can also be used as a booster compressor after an oil-free lubrication compressor, and is also suitable for various purposes when the discharge volume is small, and can be used as a small gas supply device, pneumatic regulator, Aquarium feeding tank aeration device, and now this technology is only in the hands of companies in the United States, Germany, Canada, Japan, if the domestic hydrogen fuel cell industry develops, it must be imported from abroad, and the price is determined by others, it is better to lay out in this area now, but also to further reduce the cost of our domestic fuel cell. ”

"Well, you're experts at this with your technical team, so you just have to do it. Li Kaiyuan nodded.

"Uncle Li, in addition, I also want to build a 50 megawatt fuel cell power station here in Tanzhou City, according to the electrochemistry laboratory to prepare 100 kilowatt stack cost and installation cost, we have reduced to one-third of similar foreign products, I want to build a fuel cell power station to further reduce costs. ”

Yang Jie said.

"Can you guarantee that the cost of generating electricity is lower than that of a thermal power station to build a 50-megawatt fuel cell power plant?" Li Kaiyuan asked.

"I have calculated, although the total construction cost is higher than that of thermal power stations, but the cost of power generation of fuel cell power stations is much lower than that of thermal power stations, and fuel cells have no pollution at all, and the economic and environmental benefits are much better than those of thermal power stations. ”

"What are you going to do?" asked Li Kaiyuan.

"I hope to set up a joint venture with the provincial power company to do this, and then expand the capacity to replace the thermal power plants in the province. ”

Li Kaiyuan pondered for a moment and nodded: "The province supports this matter, and I also hope that this fuel cell power plant will play a very good demonstration role in China." ”

"Thank you Uncle Lee for your support. Yang Jie said with a smile.

"It should be me saying thank you to you," Li Kaiyuan said with a smile: "If it weren't for your kid working fuel cell research and development, otherwise there would be no current situation." ”

"Now you can do this step, you have kicked the door to large-scale commercial application of fuel cells, as you said, this will be an incomparably huge industry, and more importantly, these technologies are in the hands of our country, this industry is even bigger than the mobile phone industry!"

"Uncle Li, I am very confident that in seven or eight years, fuel cells will be able to replace internal combustion engines on a large scale. Yang Jie said confidently.

"By the way, the fuel cell is a generator, presumably all kinds of motors will rise at that time, our domestic technical strength in the motor is relatively weak, and the foreign strength is very strong in this regard, is your company ready in this regard?"

"Uncle Li, these experts from the Machine Tool Research Institute are very strong in asynchronous motors, and have been doing research and development on motor materials, bearings, reliability, and control systems in recent years, and now they are also beginning to develop permanent magnet synchronous motors. ”

"Permanent magnet synchronous motors?"

"Yes, our country is very rich in rare earth resources, and the research and development of permanent magnet synchronous motors is very advantageous, because the structure of permanent magnet synchronous motors is similar to that of DC motors, so that it can have the characteristics of brushless DC motors with simple structure, reliable operation, high power density, good speed regulation performance, etc., and the volume, noise and control accuracy are the best. ”

Yang Jie continued: "Because the volume of the permanent magnet synchronous motor can be made very small, its weight can be made very light, the layout can be more flexible, and the weight of the whole vehicle can also be reduced, especially for small cars. ”

"You guys are all in one!" Li Kaiyuan said with a smile.

"We are also trying our best to squeeze out the benefits of technology patents and avoid wasting technical resources. Yang Jie said with a smile.

"By the way, I heard that this time Scania will come to inspect and discuss cooperation with Zhongyuan Automobile Company, can this negotiation be successful?"

"Li Jianfeng went to talk to the people of Scania last time, but Scania was very arrogant, they made it clear that they did not accept the joint venture, and they have been profitable all these years, and the focus is also on the Americas and the Middle East. ”

Yang Jie said: "Scania is world-class in large bus chassis and engine technology, and if we can cooperate with them, it will be very beneficial to Zhongyuan Automobile Company." ”

"Then you two should discuss the way of cooperation. Li Kaiyuan nodded.

"Okay. Yang Jie nodded in agreement.
