Design of the Converter Prototype for Powering the Hydrogen Electrolyzer
Source abstract
Abstract
Electrolysis, which uses direct current, is the most common way to produce hydrogen gas. However, its efficiency is very low, about 70%. The method used when current pulses are used by electrolysis is called pulse electrolysis. According to other studies, this method can increase the efficiency of the production of hydrogen gas by the electrolysis of water. The main objective of this paper is to present a prototype of a converter that provides current pulses with specific parameters. This converter can produce positive and negative pulse-modulated current pulses of defined amplitude and duty. Also, the number of positive and negative pulses in one working cycle is adjustable. This converter’s design enables us to research pulse water electrolysis, its electrical behavior, and the possibilities of increasing the efficiency of the electrolysis process. While this paper focuses on the development of the prototype for future research, the technology could be extended to other applications requiring precise current pulse control.
