Hydrostatic pressure test, burst test and normal temperature pressure cycle test of composite hydrogen cylinder of 35MPa, 70MPa

Hydrogen energy is considered to be the most promising clean energy in the 21st century because of its abundant reserves, high combustion value and regenerability. It has important strategic significance for solving the two problems of “energy shortage” and “environmental pollution” that currently plague the world. With the development of fuel cell technology, hydrogen fuel cell vehicles are gradually becoming a hot spot for the world's auto manufacturers. The high-pressure hydrogen storage technology has the advantages of simple structure, fast charging and discharging, compressed hydrogen low energy consumption and other advantages, It is the main hydrogen storage method adopted by hydrogen fuel cell vehicles. The composite hydrogen cylinder has strong pressure bearing capacity, light weight and good corrosion resistance. It is the preferred type of hydrogen cylinder for hydrogen fuel cell vehicles. Since the stored medium is flammable and explosive hydrogen, it has potential leakage and explosion hazard during use, so its safety performance is the key to the widespread acceptance and market promotion of hydrogen fuel cell vehicles.
