Problems solved by technology

The decrease of hydrogen purity makes hydrogen unable to meet the design needs and production safety, and cannot meet the user's requirements for high-purity hydrogen use. Therefore, it is necessary to test the change of hydrogen purity before and after hydrogen storage and discharge to find out whether there is any reason that affects the hydrogen purity, so as to find out the improvement. measure

Abstract

The invention relates to the technical field of hydrogen storage material performance testing, and discloses a system for testing multiple properties of a hydrogen storage material. The system comprises a main pipeline, a high-pressure gas source subsystem, a gas storage subsystem, a reaction subsystem, a temperature control subsystem, a thermal conductivity monitoring subsystem, an exhaust subsystem, a data acquisition and processing subsystem, a first pressure sensor and a second pressure sensor. The system can complete calibration of the volume of the reaction chamber, measurement of the leakage rate of the reaction chamber, performance test of the hydrogen storage material under different hydrogen purities, measurement of the hydrogen purities before and after hydrogen storage / release,test of the cycle life of the hydrogen storage material under different initial hydrogen purities and the like. The invention also discloses a test method of the system for testing the multiple properties of the hydrogen storage material. The system and method are controlled by a computer, convenient to operate, complete in measurement parameters and high in accuracy, so that the performance of the hydrogen storage material under different hydrogen filling purities can be better obtained.

Description

technical field [0001] The invention relates to the technical field of performance testing of hydrogen storage materials, in particular to a testing system and a testing method for multiple performances of hydrogen storage materials. Background technique [0002] As a clean energy, hydrogen has the characteristics of large reserves, easy preparation, and no pollution. Under the background of building a resource-saving and environment-friendly society, hydrogen has great potential as a new energy to replace traditional energy. The production, storage and transportation of hydrogen are all key issues in the utilization of hydrogen energy. [0003] Existing hydrogen storage technology can be divided into three types, one is gaseous hydrogen storage technology, which compresses hydrogen and stores it in a high-pressure container; the other is liquid hydrogen storage technology, which stores hydrogen in a heat-insulated container after being liquefied at low temperature and high ...
