“…However, the number of the cells has to be limited in order to guarantee a high reliability of the PEM EL. Currently, this compromise between the EL reliability and its stack voltage (which is the sum of each cell voltage) is a challenging issue for EL applications [4]. Generally, step-down DC/DC converters are used to supply PEM ELs; whereas for fuel cell applications, step-up converters are preferred.…”

“…Indeed, for electrical systems including wind turbines, the DC bus voltage is very high (i.e. between a hundred and a thousand volts) [4]. Besides, current hybrid renewable energy systems with hydrogen storage based on a DC bus configuration are limited to low-power applications due to the use of classic DC/DC converters (buck for PEM EL) [17].…”

“…These topologies are built by connecting in parallel N buck converters (from N=2 to N=6) with a common DC bus [4]. They present several benefits compared to the classic buck converter, especially from energy efficiency, output current ripple reduction and reliability point of view [4]. Generally, a three-leg interleaved buck converter (IBC) is preferred for optimization reasons (i.e.…”

“…As highlighted in a previous review work [4], three types of DC-DC converters are currently used for PEM EL applications, such as buck, half-bridge, and full-bridge DC-DC converters. However, these classic converters are not optimized from voltage ratio, energy efficiency, output current ripple minimization, and availability point of view.…”

“…Water electrolysis is based on an electrochemical reaction using electricity to split water into hydrogen and oxygen; it is carried out by means of an electrolyzer (EL). There are three types of ELs in the literature: proton exchange membrane (PEM) EL, alkaline EL, and solid oxide EL (the latter exists only in the field of research and development) [4].…”

Recently, the use of electrolyzers for hydrogen production through water electrolysis is of great interest in the industrial field to replace current hydrogen production pathways based on fossil fuels (e.g. oil, coal). The electrolyzers must be supplied with a very low DC voltage in order to produce hydrogen from the deionized water. For this reason, DC-DC step-down converters are generally used. However, these topologies present several drawbacks from output current ripple and voltage gain point of view. In order to meet these expectations, interleaved DC-DC step-down converters are considered as promising and interesting candidates to supply proton exchange membrane (PEM) electrolyzers. Indeed, these converters offer some advantages including output current ripple reduction and reliability in case of power switch failures. In addition, over the last decade, many improvements have been brought to these topologies with the aim to enhance their conversion gain. Hence, the main goal of this paper is to carry out a thorough state-of-the-art of different interleaved step-down DC-DC topologies featuring a high voltage gain, needed for PEM electrolyzer applications.

Four novel heteroleptic Cu(I) photosensitizers with 3,8‐diaryl‐2,9‐diisopropyl‐1,10‐phenanthroline derivatives as electron‐donating bidentate N‐ligands have been designed and synthesized. The metal copper complexes are studied in light‐driven water reduction system. And the substituent effect at the 3,8‐positions of N‐ligands impacting on photosensitive activity and photoelectric chemical properties are explored and discussed. Surprisingly, with the enhancement of electron‐donating capacity of substituent group at 3,8‐sites of 1,10‐phenanthroline, the photosensitive activity of photosensitizer linearly increases, and photocatalytic performance up to 817 turnover numbers (TON) was reached combining with water reduction catalyst (WRC), Fe3(CO)12. The photocatalytic performance of these photosensitizers dramatically increased compared to 2,9‐diispropyl‐1,10‐phenanthroline complex (TON = 89). Moreover, the introduction of methoxy substituent to copper complexes, which could increase the fluorescence lifetimes (τmax = 209 ns) and promote hydrogen evolution.
