Polymer electrolyte membrane (PEM) electrolyzer or alkaline is required to produce green hydrogen using renewable energy such as wind and/or solar power. PEM and differ in many ways, instantly basic materials, system configuration, operation characteristics are different. Building an optimal water hydrolysis by closely grasping the of each type great help building a safe ecosystem well efficien...

Composite electrodes of yttria-stabilized zirconia (YSZ) with La0.8Sr0.2MnO3 (LSM), La0.8Sr0.2FeO3 (LSF), and La0.8Sr0.2CoO3 (LSCo) were prepared and tested as solid oxide electrolyzer (SOE) anodes and solid oxide fuel cell (SOFC) cathodes at 973 K, using cells with a YSZ electrolyte and a Co-ceria-YSZ counter electrode. The LSM-YSZ electrode was activated by cathodic polarization but the enhan...

This paper proposes the optimal fuzzy logic based-proportional-integral-derivative (FLPID) controller design of the electrolyzer (EZ) by a bee colony optimization (BCO) for microgrid (MG) stabilization. The study MG system consists of wind power (WP), photovoltaic (PV), fuel cell (FC) equipped with EZ, diesel generator, and load. The intermittent power generations from WP and PV cause the sever...

The governing reaction mechanisms, and the electrode material compositions and structures, that controls the efficiency of the solid oxide fuel cells (SOFC) and solid oxide electrolysis cells (SOEC) need to be identified and well-understood for significant technological improvements. Our study on the oxygen electrodes focuses on specifically the effect of electrode crystal structure and morphol...

Electrocatalytic splitting of water by means renewable energy as the electricity supply is one most promising methods for storing green hydrogen. Although two-thirds earth's surface covered with water, there inadequacy freshwater in parts world. Hence, seawater instead could be a truly sustainable alternative. However, direct faces challenges because complex composition seawater. The compositio...

The application of photovoltaic (PV) power to split water and produce hydrogen not only reduces carbon emissions in the process production but also helps decarbonize transportation, chemical, metallurgical industries through P2X technology. A techno-economic model must be established predict economics integrated PV–hydrogen technology at key time points future based on characteristics, variabil...
