Performance optimization of PEM electrolyzers: An experimental and Taguchi-based approach
In this study, the performance of a proton exchange membrane (PEM) water electrolyzer with an active area of 9 cm2 was investigated under various operating conditions. At the anode, a three-layer titanium cross-mesh along with a fiber felt structure is employed. A total of twenty-seven experiments are conducted according to Taguchi's design of experiments to investigate extremes of operating temperature (40 °C, 60 °C, 80 °C), clamping torque (5 Nm, 7 Nm, 10 Nm), and water flow rates (10, 20, 30 mL/min) on hydrogen production and current density. From these experiments, it was noticed that temperature has the most notable influence by enhancing reaction kinetics and membrane conductivity. Clamping torque improves the electrode-membrane contacts and reduces internal resistance. Water flow rates have an effect on membrane hydration and gas removal, although somewhat less so. The three-layer mesh structure enables effective water distribution and gas evacuation, leading to lower overvoltage and steady operation. The best results came at 80 °C, torque of 10 Nm, and flow rate of 10 mL/min. Thus, the findings emphasize the dominant role of temperature and show that clamping torque should not only be regarded as a mechanical factor but also as an electrochemically active design factor in PEM electrolyzer design.
期刊介绍:
The objective of the International Journal of Hydrogen Energy is to facilitate the exchange of new ideas, technological advancements, and research findings in the field of Hydrogen Energy among scientists and engineers worldwide. This journal showcases original research, both analytical and experimental, covering various aspects of Hydrogen Energy. These include production, storage, transmission, utilization, enabling technologies, environmental impact, economic considerations, and global perspectives on hydrogen and its carriers such as NH3, CH4, alcohols, etc.
The utilization aspect encompasses various methods such as thermochemical (combustion), photochemical, electrochemical (fuel cells), and nuclear conversion of hydrogen, hydrogen isotopes, and hydrogen carriers into thermal, mechanical, and electrical energies. The applications of these energies can be found in transportation (including aerospace), industrial, commercial, and residential sectors.
