Compared to other hydrogen production methods, the hydrogen production method using plasma decomposition has a high ideal efficiency, but the measured efficiency is low. This is because it is a submerged method in which plasma generation depends on the amount of bubbles produced, and energy is lost through thermal diffusion. Therefore, in this study, we aimed to improve efficiency by using a device that fills the area around the plasma with vaporized raw material and a heat regeneration system. As a result, we were unable to achieve an improvement in efficiency. In the future, we will aim to improve efficiency by increasing the residence time of the liquid raw material around the plasma.
