Abstract

The invention relates to wide temperature zone hydrogen storage material low temperature hydrogen storage performance testing device, belonging to the low temperature engineering and low temperature technical field and being applicable to measuring low temperature hydrogen storage performance of multiple hydrogen storage materials in wide temperature zone. The testing device comprises a liquid nitrogen Dewar, a high pressure hydrogen gas cylinder, a vacuum set, a data acquisition computer, a temperature acquiring device, a PID temperature controller, a flange, a platinum resistor, a sample room, a heating wire, a cooling coil, a thermocouple, a Dewar, a vacuum gauge, a pressure sensor and a valve. The testing device takes circulating liquid nitrogen as cooling working medium and combines electrical heating to realize temperature regulation in wide temperature zone. The PID temperature controller regulates heating amount of the heating wire by the temperature signal acquired by the thermocouple. The pressure sensor and temperature acquiring device transmit the acquired data to the data acquisition system. The flange of sample room is arranged at the bottom of the sample room, inner Dewar and outer Dewar flanges are welded into a whole, thus ensuring replacement of sample. The testing device is simple in structure, is easy to manufacture and has better economy.

Description

technical field [0001] The invention relates to a low-temperature hydrogen storage performance test device for a hydrogen storage material. In particular, it is a low-temperature hydrogen storage performance test device for hydrogen storage materials in a wide temperature range using metal-organic framework materials as hydrogen storage materials. It belongs to the field of cryogenic engineering and cryogenic technology. Background technique [0002] As a green energy with abundant reserves, wide sources, low carbon content and high chemical combustion value, hydrogen energy is an ideal substitute for fossil fuels and one of the main new energy sources in the 21st century. As a new type of clean energy, hydrogen's cheap production, safe and efficient storage and transportation, and large-scale application are the key topics of current research, and the storage of hydrogen is the key to the application of hydrogen energy, especially when it is used in motor vehicles, the mai...
