Our company undertook the National High tech Research and Development Plan of the 11th Five Year Plan and 863 in 2007, and successfully developed and developed hydrogen energy vehicle bottles. Significant breakthroughs have been made in the "energy-saving and new energy vehicle projects" in the field of modern transportation, bringing China's high-pressure hydrogen storage container manufacturing technology to the international advanced level and filling the domestic gap. At the 2010 Shanghai World Expo, our company's fully wound hydrogen aluminum alloy inner liner carbon fiber gas cylinder for vehicles was successfully applied, which was the first in China and won the second prize of the Shanghai Science and Technology Progress Award. In the same year, this product won the second prize of the National Science and Technology Progress Award. In 2011, the "Key Technology and Application of 70MPa High Pressure Gas Hydrogen Storage System" project won the first prize of the National Ministry of Education Science and Technology. At present, our company's 70MPa hydrogen cylinder has passed type testing and is the first in the country.
