Characterization, Modelling, Control, and Aging of Electrolyzers

The water electrolysis process involves exploiting electricity derived from low-carbon power sources and pure water (the use of seawater is also considered but remains problematic) to make clean hydrogen that can be used to store energy, supply fuel cells for electricity generation in transportation, for industrial/commercial/residential buildings, and for power-to-X applications such as the generation of green gas.

The water electrolysis process is made possible thanks to the use of electrolyzers. Currently, four electrolyzer technologies have been reported in the literature, depending on their electrolyte material and ionic species they transport: alkaline water electrolysis, proton exchange membrane (PEM) water electrolysis, solid oxide (SO) water electrolysis, and the recently-introduced anion exchange membrane (AEM) water electrolysis. Among these four technologies, only alkaline, PEM, and AEM electrolyzers have reached a commercial stage. However, there remain some challenging issues in terms of modelling, control, and aging.

When coupled with intermittent renewable power sources and power electronics, electrolyzers can be subjected to material and component degradation leading up to a decrease in their performance. For this reason, it is crucial to have an improved understanding of their behaviours and stack degradation mechanisms because of dynamic operating conditions and current ripple from power electronics. Mitigation strategies are therefore needed to optimize the performance of electrolyzers and their durability.  Furthermore, due to the possibility of degradation during their operation, it is crucial to design and develop electrolyzer emulators, which can be used to test new power electronics topologies and control without damaging a real electrolyzer. Finally, in electrolyzers, the membrane electrode assembly (MEA) can be subjected to different failures such as membrane break, internal gas leakage, cell flooding or drying, and poisoning of the catalyst areas. Only by enhancing electrolyzer technologies might hydrogen be introduced as a safe and sustainable energy carrier.

This Article Collection aims to attract original high-quality papers and review articles focused on electrolyzers, related to their characterization, modelling, control, aging, failure diagnosis, and faulty operation management.

Prospective authors may submit contributions dealing with (but not limited to) the following subtopics:

  • Characterization and modelling of electrolyzers under dynamic operating conditions when coupling with intermittent renewable power sources
  • Design and development of electrolyzer emulators
  • Power electronics topologies and their control
  • Impacts of dynamic operating conditions on the materials and components degradation of electrolyzers
  • The impact of operating conditions (temperature, pressure, current density) and power electronics (current ripple) on the aging of electrolyzers
  • Failure mechanisms in electrolyzers
  • Development of failure diagnosis methods
  • Development of faulty operation management to enhance system performance
