Automatic hydrogen storage material cycle life tester and testing method

Abstract

The invention discloses an automatic hydrogen storage material cycle life tester and a testing method belonging to the technical field of hydrogen storage. The automatic tester comprises a gas sourcepart, a sample tank part and an evacuation system which are connected with a system main body, wherein a temperature control system is arranged outside the system main body and the sample tank part, and a computer, the temperature control system, the system main body, the gas source part, the sample tank part and the evacuation system are all connected with a data acquisition system and an automatic control system. According to the testing method, after sample loading, sample tank part volume calibration, system main body vacuumizing and parameter setting, subsequent hydrogen storage materialactivation and hydrogen charging and discharging circulation operation can be automatically carried out. According to the invention, hydrogen charging and discharging pressure and valve opening and closing are automatically controlled, test result deviation caused by manual operation system and data recording is avoided, manpower and time cost in long-time continuous cyclic test can be saved, andtest efficiency and test accuracy are improved.

Description

technical field [0001] The invention belongs to the technical field of hydrogen storage, and in particular relates to an automatic tester and a test method for the cycle life of hydrogen storage materials. Background technique [0002] Hydrogen energy has excellent characteristics such as renewable, wide range of materials, high calorific value, good combustion performance, non-toxic and non-polluting. It can replace traditional fossil fuels and is regarded as the clean energy with the most development potential in the 21st century. To research and develop hydrogen energy, we must first solve the problem of safe storage and transportation of hydrogen. Hydrogen storage materials are a class of materials that can reversibly absorb and desorb hydrogen, and reversibly convert hydrogen between hydrogen and hydride. The use of hydrogen storage materials for hydrogen storage can well solve the problems of high energy consumption and poor safety of hydrogen storage in high-pressure...

[0006] Chinese Patent No. ZL200810205106.X "A Fully Automatic Performance Tester for Hydrogen Storage Materials and Its Test Method" Wu Zhu, Kong Xiangcheng, etc. disclose a fully automatic performance tester for hydrogen storage materials. The hydrogen absorption and desorption P-C-T curve of the hydrogen material is tested, focusing on the test method of the material hydrogen absorption and desorption P-C-T curve. It can only complete the automatic operation of a single hydrogen absorption or single hydrogen desorption at a certain temperature. And during the cycle of hydrogen depletion, it is necessary to manually remove the hydrogen storage tank from the water bath after absorbing hydrogen, and then put it into the heating furnace for dehydrogenation. It is impossible to realize the cycle and continuous charge and discharge of hydrogen without human intervention on the hydrogen storage material. Operation, such as using this equipment to test the cycle life of hydrogen storage materials, the test efficiency is low
