Special Issue Information

Dear Colleagues,

The greenhouse effect of this century is increasing, and hence, a reduction of carbon dioxide emissions through various methods is the global consensus. Developing green and renewable energy has been the main target until now. However, the major issue of renewable energy is the unstable output of power that is affected by seasonal and environmental factors, which results in electric grid management difficulties. The advantages of proton exchange membrane water electrolysis (PEMWE) for energy storage during off-peak periods are its high current density, high purity gas production (H2 and O2), and compact system. The supply of stored hydrogen and oxygen gas for the fuel cell is used to generate power during the peak-hour period. Additionally, accompanied with a higher operating voltage and proper anode materials, ozone (O3) gas will be generated in addition to oxygen. Ozone is a natural and effecitve disfection gas. The PEMWE technique, which produces three kinds of gases (H2, O2, and O3), will expand the application area from green energy to green technology.

This Special Issue will highlight the importance of the components (membrane, anode/cathode, membrane electrode assembly, and stack), PEMWE systems, and their applications. It welcomes both original contributions and reviews related, but not limited, to the issues as stated above.

In this study, an electrochemical model was incorporated into a two-phase model using OpenFOAM® (London, United Kingdom) to analyze the two-phase flow and electrochemical behaviors in a polymer electrolyte membrane water electrolyzer. The performances of serpentine and parallel designs are compared. The current density and overpotential distribution are analyzed, and the volume fractions of oxygen and hydrogen velocity are studied to verify their influence on the current density. The current density decreases sharply when oxygen accumulates in the porous transport layer. Therefore, the current density increased sharply by 3000 A/m2 at an operating current density of 10,000 A/m2. Maldistribution of the overpotential is also observed. Second, we analyze the behaviors according to the current density. At a low current density, most of the oxygen flows out of the electrolyzer. Therefore, the decrease in performance is low. However, the current density is maldistributed when it is high, which results in decreased performance. The current density increases abruptly by 12,000 A/m2. Finally, the performances of the parallel and serpentine channels are analyzed. At a high current density, the performance of the serpentine channel is higher than that of the parallel channel by 0.016 V. Full article
