It is reported that the hydrogen refueling station in Europe, the United States and Japan and the car commonly used 70MPa pressure standard, and equipment production. Japan from the system to encourage the car hydrogen pressure of a single inflatable bottle of safe ceiling value increased from 70MPa to 88MPa, further technical upgrades. From the perspective of specific equipment, hydrogen compressor: the United States PDC and other companies have mastered the three-tier metal diaphragm structure of the hydrogen compressor manufacturing technology, the output pressure limit of more than 85MPa; high-pressure hydrogen tank: the United States, Canada, Japan and other countries are available Production of pressure over 70MPa of carbon fiber composite materials and aluminum alloy and other materials made of high pressure hydrogen storage containers; hydrogen filling machine: German Linde, the United States Air Chemical and other enterprises 70MPa hydrogen filling machine safety and intelligence than High, and mass production.
China's "Twelfth Five-Year Plan" 863 project, advanced technology and energy field "based on renewable energy / hydrogen storage 70MPa hydrogenation station research and development and demonstration project", successfully passed the high-tech Division of Science and Technology project acceptance, marking Tongji University hydrogen Research in the field of technology is at the international advanced level. The project led by Tongji University, joint Shijiazhuang Enric Gas Machinery Co., Ltd., Beijing Tian Gao Membrane Compressor Co., Ltd. and Shanghai Shunhua New Energy System Co., Ltd. formed a project team.http://www.wxytgas.com/
