In 2007, our company undertook the 11th Five-Year Plan 863 National High-tech Research and Development Plan and successfully developed and developed hydrogen energy vehicle bottles. Major breakthroughs have been made in the "Energy Saving and New Energy Vehicle Project" in the field of modern transportation, bringing my country's high-pressure hydrogen storage container manufacturing technology to the international advanced level and filling domestic gaps. At the 2010 Shanghai World Expo, our company's automotive hydrogen aluminum alloy liner carbon fiber full-wound gas cylinder has been successfully applied, which is the first in China. It won the second prize of Shanghai City Science and Technology Progress Award. In the same year, this product won the second prize of National Science and Technology Progress Award. In 2011, the "Key Technologies and Applications of 70MPa High-Pressure Gaseous Hydrogen Storage System" project won the first prize of Science and Technology Award by the Ministry of Education. At present, the 70MPa hydrogen cylinder produced by our company has passed the type test, making it the first in the country.
