The laboratory has a 105MPa high-pressure hydrogen circulation test bench, which can conduct high-pressure hydrogen circulation tests on core components of hydrogen storage systems at temperatures ranging from -40 to 85 ℃. Hydrogen permeation tests can be observed through gas chromatography, with a maximum allowable pressure of 105MPa, while meeting international and domestic testing requirements such as GTR 13, GB/T 42612, GB/T 42610, GB/T 42536, ECE R134, etc. The operation of this experimental equipment has provided tremendous support for the research and development of IV type bottles in China. At present, Test H Hydrogen Energy Testing has reached a long-term strategic cooperation agreement with Dalian Boiler and Pressure Vessel Inspection and Testing Research Institute Co., Ltd.
