抄録

In a recent work, a hydrogenation process of palladium has been studied by the acoustic emission (AE) method with a new gas pressure cell. The high H₂ gas pressure condition can, however, be easily provided by an electrochemical hydrogen charging technique. In this paper, characteristic AE power spectra caused by cavitation and/or bubble burst have been appraised by using an electrochemical separated AE cell. A typical AE signal induced by Pd hydride formation has been observed. The fundamental AE mode was 250 kHz in the Pd hydride formation stage, which was equal to the frequency measured by using the gas pressure cell as a standard hydrogenation technique.
