Special Issue Information

Dear Colleagues,

Proton exchange membrane fuel cells (PEMFCs) play an important role in the development of green energy, and have drawn much attention during the past decade. They have been widely employed as power sources for electric vehicles, unmanned aerial vehicles, underwater vehicles, and other power generation systems. Recently, fuel cell research has focused on cost reduction and durability improvement to enhance fuel cell commercialization. The cost and performance of PEMFCs are influenced by many factors, including materials of key components, structures of membrane electrode assemblies, manufacturing processes, and operating conditions. How these factors influence the electrochemical reaction within the PEMFC is an interesting and essential topic for the development of PEMFCs.

This Special Issue aims to showcase recent progress and breakthroughs in the cost reduction and performance improvement of PEMFCs, including both high- and low-temperature PEMFCs. For this Special Issue, we welcome and encourage contributions covering representative models or experimental studies that can capture flow characteristics, catalytic activity, gas management, energy efficiency, and degradation mechanisms.

A solid oxide fuel cell (SOFC) is an electrochemical cell that converts chemical energy into electrical energy by oxidizing fuel. SOFC has high efficiency and cleans oxidation residues. Research has shown the importance of SOFC control. Voltage output control is needed because of nonlinearity, slow dynamics, and proper SOFC operating restrictions. This study aims to design an SOFC simulator with output voltage control to optimize the flow rate of fuel (hydrogen) and air (oxygen). This SOFC simulator is designed based on a microcontroller model. The controller is designed using the fuzzy logic method. Tests show that the output voltage can approach the set point with an average of 340.6 volts. The pressure difference (∆Pressure) between the two gases averaged 4428 Pa, and the fuel/gas flow rate was in the range of 0.7 mol/s. The controller can correct both the output voltage of the SOFC simulator and the difference in gas pressure under 8106 Pa (0.08 atm). Full article
