Abstract
The production of hydrogen fuel depends basically on the water electrolysis. The study on the decrease of overpotential which activates the hydrogen production is the core to elevate the hydrogen production efficiency on principle. Characteristics on the overpotential decrease are observed through the micro reaction by ultrasonic in electrolytic cell. For the above, the electrochemical analyzer, i.e., BAS is applied, Experiments with ultrasonic forcing into 4 kinds of solution such as city water, city water plus nitrogen. distilled water, and distilled water plus nitrogen are carried out. And concentrations of KOH are 0%, 10%, 20% and 30%. The basic characteristics of the overpotential decrease are obtained through the analysis by LSV technique in sweep technique. In results, it is clarified that the ultrasonic influences the decrease of overpotential to obtain the efficiency elevation of hydrogen fuel production.
