Abstract

Abstract: This study simulated hydrogen production scenarios for fuel cell electric vehicle (FCEV) hydrogen refueling stations by examining an electrolysis hydrogen production system powered by small wind turbines and a PV system. The simulation model was developed using MATLAB/Simulink to observe the effect of temperature on hydrogen flow and Faraday efficiency in the electrolyzer. In the simulation, the decentralized hybrid renewable energy system generated power used to produce hydrogen in the electrolyzer at an internal temperature of 40 °C, 60 °C, and 80 °C. The results of the simulation showed that electrolysis hydrogen production efficiency improved under two conditions: (a) when the 12 kW-rated power turbines operated simultaneously with the 18 kW PV system for a total power output of 30 kW; and (b) when the electrolyzer was heated to an operating temperature of 60 °C using the solar thermal collection system. If improvement in per second hydrogen flow can approach 0.1% compared to 40 °C, the system could produce 25 kg of hydrogen in the shortest time, at 49.2 h and I-100 current density.
