Electrolyzer Application of a Load-Managing PV System

Mentor:
Research Theme: Energy
FURI: Spring 2020

The purpose of this research was to determine the effectiveness of electrolyzers implemented within a load-managing PV system. The electrolyzers replace the initial system’s test resistors, which have shown power efficiency of up to 99%, and create a real application by generating sustainable hydrogen gas. The electrical model of the electrolyzer shows that using load management for electrolyzers is effective for approximating the maximum power for daily irradiances. Four stacks of 15 electrolytic cells are being physically modeled by an assortment of diodes with the load-managing control algorithm and solar panel to confirm the viability of the electrolyzer application.

Electrolyzer Application of a Load-Managing PV System

Mentor:
Research Theme: Energy
FURI: Fall 2019

The purpose of this research was to determine the effectiveness of electrolyzers implemented within a load-managing PV system. The electrolyzers branch the system’s loads from test resistors, which have shown power efficiency of up to 99%, to real applications by generating sustainable hydrogen gas. An electrical model for the terminal behavior of a single electrolyzer at a resistance of 0.2 Ω*cm2 was derived from a linear fit of experimental data with an r2 value of 0.999. The electrolyzer models will be optimally configured in series and parallel, where simulations can be done with the PV system to determine the efficiency.
