Interview with Dr. Hu Liqing, General Manager of Shanghai Shenli Technology Co., Ltd.
The reporter Song Li’s intern Zhang Yi
“Traditional cars consume about 7 liters of gasoline per 100 kilometers, and they cost about RMB 28 per litre at the market price, while vehicles equipped with the supernatural hydrogen fuel cell engine consume 1.2 kilograms of hydrogen per 100 kilometers. Calculated at 6 yuan per kilogram, it only costs 7.2 yuan, and the operating cost is equivalent to one-fourth of the former.†Dr. Hu Liqing, general manager of Shenli Technology Co., Ltd., gave this reporter an economic account that gave the reporter a whole new look: It is able to save energy and protect the environment, achieve sustainable development, and more effectively save people's pocket money.
Hydrogen fuel cell vehicles are the ultimate direction of research in the automotive industry. The divine power company led by Hu Liqing successively completed the "9th Five-Year Plan" key scientific and technological breakthrough plan "Proton Exchange Membrane Fuel Cell Technology", "The 15th '863' Plan Electric Vehicle Major Project", Shanghai's major scientific and technological projects, etc. The seven national key scientific research tasks have made important progress in fuel cell technology R&D and industrialization, and have reached international advanced level. Some innovative technologies have also reached the international advanced level and have been applied in China and the United States. Atmospheric pressure operation proton exchange membrane fuel cell technology patents 232 (of which 11 US patents). Dr. Hu Liqing’s name has been known to automotive professionals around the world. When he mentioned the time he had just returned to China, Dr. Hu couldn't help but smile: "At that time, people thought I was crazy, but there is a good thing that 'changes to water'!" But facts speak louder than words. This year, the third hydrogen energy Fuel cell prototype prototype engine has been tested in Tsinghua University, the total evaluation received the highest score of 92.9, almost all project indicators have reached the national "863" requirements: for its rated work required for one hour static output of 100 kilowatts, overload The maximum power of 130 kilowatts, God has done it. And its weight ratio of power exceeds 130 watts per kilogram, hydrogen fuel efficiency has reached 51%, greatly exceeding the contract requirements, ahead of the international. Compared with other competing companies that jointly undertook the “Fuel Cell Engine Project†in the “15th Five-Year Plan†and “863 Electric Vehicle Major Projectâ€, Shenli Company strived for the best and became the protagonist of the clean car energy stage, not only for our country. The development of the automobile industry has provided new technical resources and has further enhanced the status of China's automobile industry in the international arena.
7 years ago, Hu Liqing returned to China with his hydrogen dream. He fully understands that China lacks advantages in internal combustion engine technology. Engaging in internal combustion engines is not China's strength, but it is still at the starting stage of hydrogen fuel cell technology with developed countries. Once technological breakthroughs are made and recognition is achieved, it will not be accepted.
He confidently believes that by virtue of his own professional advantages, he will be able to participate in international competition in the field of hydrogen fuel cells and achieve leapfrog development for the Chinese automotive industry. In China, with the exception of Hu Liqing, no one can do the most difficult thing. "I'm not going to hell. Who is going to hell?" Hu Liqing gave up the generous treatment abroad and returned home to work for the Chinese auto industry. He shouldered the burden of the nation. Resolutely decided to start hydrogen fuel cell research and development. “The national industry of a country must have its own core technology. The Chinese auto industry must surmount and leapfrog in development to be competitive.†“5 years ago, the Ministry of Science and Technology looked far and forward and accurately recognized the long-term prospects of fuel cell engines. Investing nearly half of the research and development funds for the research and development of pure electric engines, hybrid electric motors, and fuel cell engines into the development and utilization of fuel cells, the facts prove that this is a wise decision. The results were inseparable from the strong support of the government; I did not let the country down and I was relieved,†Dr. Hu said with gratitude.
Regarding how to realize the industrialization of hydrogen energy fuel cells, Dr. Hu was filled with emotion: “The results achieved by Shenli today can't pull the upstream and downstream industrial chains. The country can absolutely not expect the hydrogen energy fuel cell technology to be automatically industrialized. In the hydrogen energy fuel cell industry chain, only the core technology links will not work, and the entire industrial economy needs to be recycled, such as raw materials, vehicle equipment, technical support, hydrogen refueling stations, transportation safety regulations and standards, and so on. In the industry chain, when the industry does not form a certain scale, it needs government's promotion. The government should stand at the strategic height to guide development, formulate preferential policies, increase supportive efforts, and make necessary in certain areas. Demonstration: Only a small-scale industrialization has been realized in the region, and it has been continuously developed to a certain extent, so that private capital can understand its industrialization process, the government can withdraw, encourage private capital to invest in the production of hydrogen refueling stations, and involve in production. Supply of raw materials, etc. to promote its industrial development."
Not long ago, Zhou Yipeng, deputy mayor of Shanghai, disclosed to Hu Liqing a message when he inspected Shenli Company: “Shanghai will stipulate in the 2010 5.2 square kilometre Expo that all vehicles, be it bus or taxi, must all be The use of fuel cell vehicles does not allow any other polluting vehicles to enter.†Many citizens are worried about the safety of hydrogen fuel cells. Knowing this, Dr. Hu Liqing smiled frankly, thinking that there is no need to worry. He told reporters that the World Hydrogen Association recognized that hydrogen is inherently safer than gasoline. Hydrogen fuel cell vehicles generally use high-pressure hydrogen tanks. A fuel cell vehicle research institute in Japan has done tests: When a gun is used to press a high-pressure hydrogen tank, hydrogen is always upward due to the high pressure and its own proportion of light, plus the passenger compartment is isolated from the hydrogen fuel cell engine and the fire is over. The car itself is still intact, it does not explode, and the passengers are safe; but if the tank is shot one shot, the whole car will explode, burn and be scrapped, and passenger life is not guaranteed. The test results show that, especially in the open state, hydrogen fuel cell vehicles will be very safe to use, and everyone can ride with ease.
General Secretary Hu Jintao visited Ballard in Canada on September 17 this year. His president is interested in helping China develop hydrogen batteries and can make technology transfer, but the cost will be very high. Shenli Company deeply feels that the country pays attention to fuel cell technology and strengthens the confidence of independent innovation and development of China's core technology. The Chinese market cannot be controlled by foreigners. Otherwise, it will be passive and be in a state of "beating." In particular, in the revolutionary hydrogen industry, we must surpass foreign countries, and we must gradually achieve large-scale production and win strength in the contest. Dr. Hu Liqing has made plans for Shenli Company. During the Beijing 2008 Olympic Games and the 2010 Shanghai World Expo, he will develop hundreds of buses and 1,000 cars to use, allowing these environmentally-friendly, clean, high-tech vehicles to gallop on China's land.
