Multi-objective optimization through experimental technical investigation of a green hydrogen production system

In this research paper, optimization is done by performing experiments and optimizing the system based on the component specifications. The types of equipment used in the system are solar photovoltaic system, wind power plant, Proton Exchange Membrane (PEM) electrolyzer, and PEM fuel cell. To perform the multi-objective, various aims are selected, such as green hydrogen production, hydrogen leakage rate, fuel cell utilization applications to drive the motor wheel or light the lamp, hydrogen consumption rate, and overall efficiency of the system. The result demonstrates that the green hydrogen production rate depends upon the current, and voltage supply given by the system, the system leakage rate is about 0.4 ml/min, the calculated efficiency of the PEM electrolyzer, PEM fuel cell, lamp, motor, Overall efficiency of the system from electrolyzer to lighting the lamp or from electrolyzer to drive motor wheel are 74.19%, 25.24%, 74.51%, 56.56%, 14.14% or 10.59% respectively. Also, the rate of hydrogen consumption to lighten the lamp is observed as 2.66 ml/min., whereas in a motor to drive the wheel is 0.33 ml/min. Finally, conclude that from green hydrogen production to consumption the overall conversion losses are less to lighten the lamp, as compared to driving the motor wheel, but hydrogen consumption in automobile applications is eight times less than electricity.
