According to the website of the Ministry of Science and Technology on the 21st, China University of Science and Technology recently designed a cocatalyst with an atomic-accuracy shell structure. While reducing the amount of precious metal platinum promoters, the performance of photocatalytic water-producing hydrogen has been greatly increased. The results have been published in internationally renowned chemistry. The journal "German Applied Chemistry". According to reports, the design replaces metal platinum with a relatively inexpensive palladium core, reducing the material cost by more than one-third. According to the Shanghai Securities News on December 22, the technology will effectively reduce the cost of hydrogen production and fuel the development of fuel cell vehicles. Recently released the "13th Five-Year" electric vehicle charging facilities award policy draft, fuel cell passenger and passenger cars than the standard car conversion factor, up to 30 times, 50 times, indicating that the policy for fuel cell vehicles. According to estimates by the agency, the global market size of fuel cell vehicles is still in its infancy. By 2025, it is expected to soar to about 180 billion yuan, which has a potential market space. Fuel cell vehicles use a fuel cell to promote the chemical reaction of oxygen and hydrogen to generate electricity, which drives the motor and acts as a vehicle driver. The exhaust emissions during driving are zero. In the new generation of automobiles, the environmental performance is the highest and the market is regarded as the ultimate green power. Compared with pure electric vehicles, the driving distance is longer. According to public information, the mileage of hydrogen fuel cell vehicles can reach 500 to 600 kilometers, and fueling can take only 3 minutes. However, in the process of advancing the popularization of fuel cell vehicles, the high cost of hydrogen production is an important factor constraining the promotion of hydrogen energy vehicles. The company has designed a new palladium-platinum core-shell co-catalyst that can grow metal shells with a few atomic layer thicknesses without using costly atomic layer deposition techniques. Based on this technology, the photocatalytic hydrogen production efficiency is 322 times higher than the photocatalyst-free semiconductor photocatalyst and 8.2 times higher than the conventional pure platinum cocatalyst semiconductor photocatalyst system. At the same time, the design replaces metal platinum with a relatively inexpensive palladium core, resulting in a significant reduction in material costs. From a global perspective, Japan and the United States are the main players in the promotion of hydrogen energy vehicles. The Japanese government simplifies driving experiments and promotes the development of manufacturers by relaxing restrictions. In addition, each company plans to significantly reduce the price of hydrogen-fueled vehicles in order to match the popularity of fuel cell vehicles. The U.S. is also increasing its research on fuel cells. The U.S. Department of Energy has announced that it has partnered with car manufacturers, natural gas suppliers, and hydrogen and fuel cell companies to establish a program called H2USA to reduce fuel cell technology. Cost to promote hydrogen fuel cell vehicles. Audi also plans to exhibit a new hydrogen fuel cell SUV concept car Q6 h-tron at the Detroit auto show next month. China has made great progress in hydrogen energy vehicles. A new generation of fuel cell bus system technology platform has been developed. The hydrogen fuel consumption per hundred kilometers in urban conditions is 7.42 kg, and the driving range is over 250 kilometers. The company has completed the development of automotive fuel cell system solutions to key fuel cell materials and components, and has become one of the few countries in the world that has mastered the R&D, manufacturing, and testing technologies for automotive 100-kilowatt fuel cell engines. At the same time, from the aspects of new energy vehicle subsidies, charging facility incentives, and declaration of major projects, fuel cell vehicles are all targets of policy support. As technology advances and the consumer environment gradually matures, the development of fuel cell vehicles will also enter an accelerated period. A shares of Great Wall Electric, Tongji Technology and other listed companies involved in fuel cell related business.
