Abstract

This study provides the framework for optimizing a
renewable energy-connected PEM electrolyzer. PEM electrolyzer was primarily enforced onto the electrolyzer process and different electrolyzers. The Key factors that need to be considered for the electrolyzer modeling process such as basic principles, modeling equations, and stack structure. There are several coupling technologies between solar PV and electrolyzers, such as direct coupling, coupling via an electronic converter, and battery- assisted electrolyzer. A mathematical model of solar PV-connected PEM electrolyzer is developed in this project. Then the mathematical model is optimized using optimizing parameters such as the temperature of solar PV, and the Operating temperature of the PEM electrolyzer of the PEM electrolyzer.
