Outline of Final Research Achievements

In this study, nanosecond pulsed microplasma (nsPMD) has generated and applied to hydrogen production technology in order to improve the efficiency of hydrogen production energy for the realization of a hydrogen society. As a result of this study, nsPMD device with microchannels has developed by using 3D printer and ns PMD was confirmed in the gas-liquid multiphase flow in the microchannel. The efficiency of hydrogen production energy by using the device was improved by about ten times compared with the previous discharge method.
