“…PEM electrolysis is one of the most appropriate options for dynamic systems such as wind systems; Because PEM electrolyzers can maintain their performance even at high current density 28 . The efficiency of the electrolyzer depends on the current density, and the efficiency decreases with its increase 29 . Also, the overpotential of the concentration becomes significant as the current density increases.…”

The combination of wind energy as a source of production and hydrogen as a carrier and reservoir of energy has been a successful partnership. The unstable nature of wind and the long-term storage capability of hydrogen make them a prosperous pair. Many researches have been done in this field. In most of these researches, the focus has been on the production at the scale of wind farms or on the wind potential of the region. But in this project, the goal was to answer this question: is it possible to meet the energy needs of a household using the combination of wind energy and hydrogen? This project has created a step-by-step algorithm to answer this question. This algorithm starts by modeling the wind speed and finally ends by determining the overall dimensions of the system, including the active surface of the electrolyzer and the surface covered by the turbine. In this way, various components of the mini-Factory, such as electrolyzer, wind turbine, generator, and converter, have been investigated. Finally, an effort was made to select the most optimal operating conditions as well as the appropriate type for each of these components to achieve the expected output.

This paper proposes a self-sustaining control model for proton-exchange membrane (PEM) electrolysis devices, aiming to maintain the temperature of their internal operating environment and, thus, improve the electrolysis efficiency and hydrogen production rate. Based on the analysis of energy–substance balance and electrochemical reaction characteristics, an electrothermal-coupling dynamic model for PEM electrolysis devices was constructed. Considering the influence of the input energy–substance and the output hydrogen and oxygen of PEM electrolysis devices on the whole dynamic equilibrium process, the required electrical energy and water molar flow rate are dynamically adjusted so that the temperature of the cathode and the anode is maintained near 338.15 K. The analytical results show that the hydrogen production rate and electrolysis efficiency are increased by 0.275 mol/min and 3.9%, respectively, by linearly stacking 100 PEM electrolysis devices to form a hydrogen production system with constant cathode and anode operating temperatures around 338.15 K in the self-sustaining controlled mode.
