This paper presents a new integrated DC/DC converter for hydrogen-based energy storages. As compared to traditional individual converter based solutions for interfacing of an electrolyzer and a fuel cell, the proposed topology features reduced energy conversion stages. In order to improve the response time of the hydrogen buffer a battery was integrated into the interface converter with no need for an extra charging/discharging circuit. The paper analyzes and discusses the operating principle of the new converter and provides some design guidelines. Finally, theoretical background is experimentally verified.
