Investigation of Hydrogen Production System-Based PEM EL: PEM EL Modeling, DC/DC Power Converter, and Controller Design Approaches

The main component of the hydrogen production system is electrolyzer (EL), which used to convert electrical energy and water into oxygen. power converter supplies EL, controller ensure global stability safety overall system. This review aims investigate analyze each one these components: Proton Exchange Membrane Electrolyzer (PEM EL) modeling, DC/DC converters, control approaches. To achieve this desired result, a literature survey an investigation PEM EL modeling empirical semi-empirical, including static dynamic models, are carried out. In addition, other sub-models predict temperature, gas flow rates (H2 O2), pressure, efficiency for covered. converters suitable discussed in terms efficiency, current ripple, voltage ratio, their ability operate case switch failure. involves analysis strategies approaches previously objectives, robustness, reliability studying converter-PEM paper also highlights online parameter identification model adaptive issues. Finally, discussion results developed emphasize strengths, weaknesses, imperfections on subject as well proposing ideas challenges future work.
