| Abstract: |
| Objective To study the effect of electrochemical solid-state hydrogen sensor in airtight vessel filled with hydrogen. Methods A sealed hydrogen-filled environment was designed to simulate the environment with low oxygen concentration, low hydrogen concentration and variable pressure. A series of electrochemical solid-state hydrogen sensor effect experiments were conducted in this environment, and the experimental data was analyzed and evaluated. Results The variation rules of hydrogen and oxygen concentrations with time in different environments were obtained. The suitable working environment for electrochemical solid-state hydrogen sensor was found by analyzing the test data and its working life in different storage circumstances was estimated. Conclusion The temperature and pressure change in the sealed hydrogen-filled environment had great influence on the electrochemical solid-state hydrogen sensor while the humidity had little influence. For the sensors accredited in good condition by charging gas, the failure rate was high in diffusion checkup in sealed vessels, and the data error was higher than ±5%FS. |
