With the layout of China's hydrogen fuel cell vehicle demonstration city cluster project, China's hydrogen fuel cell vehicle industry has entered a fast lane of development. It is expected that by 2030, there will be more than 1 million hydrogen vehicles installed, and hydrogen fuel cell vehicles will show a trend of coexistence and development of various models such as light vans, buses, light trucks, medium and heavy trucks, and passenger cars. Laser technology is applied in the entire process of hydrogen production, storage and utilization in the fuel cell industry.

　　1) Hydrogen production stage

　　Laser welding: Electrolyzer cell frame and plates, electrolyzer nickel mesh plates, etc.;

　　Laser cleaning: Electrolyzer plates, etc.;

　　Laser cutting: Diaphragm (PPS fabric), electrode mesh/plate, cell frame flow channel, cell frame gasket laser cutting, etc.

　　2) Hydrogen storage stage

　　Laser welding: Type IV hydrogen storage bottles plastic, metal hydrogen storage bottles, hydrogen storage and transportation pipelines, etc.;

　　Laser cleaning: Metal hydrogen storage bottle welds after welding, etc.
