The article “Design and Realization of a Stacked Interleaved DC-DC Step-Down Converter for PEM Water Electrolysis with Improved Current Control” describes a low power energy conversion system to produce hydrogen via an electrolyser. The research is by ICAR-Cnr researcher Gianpaolo Vitale and aims to spread the production of low-cost hydrogen also for domestic applications where it can be used as an energy storage system or as a fuel.
