Fuel cells have received worldwide research interest as a promising energy conversion technology in the last decades. This is primarily due to their simple system design, high conversion efficiency, low carbon dioxide emissions, as well as quick fuel refueling. Among the various fuels used in fuel cells, such as hydrogen, methanol, ethanol, and ethylene glycol (EG), liquid fuels have attracted great attention due to their excellent properties. These properties include high volumetric energy density, easy storage and transportation, as well as quick refilling, making them suitable for mobile, stationary and portable devices. Research on the electrochemistry of liquid fuel oxidation reaction and oxygen reduction reaction has made great progress. The development of direct liquid fuel cells will play an important role in the future of consumer electronics, electric vehicles, and stationary power plant.
Currently, hydrogen fuel cells, including proton exchange membrane fuel cells and anion exchange membrane fuel cells, are widely studied and preliminarily commercialized. However, realizing the widespread application of hydrogen fuel cells requires researchers to address the production, transportation, and storage of hydrogen. Hence, as an alternative for power sources, a great deal of research efforts is put towards direct liquid fuel cells. Recently, numerous works have been performed, both experimentally and theoretically, to expand our fundamental understanding and provide new insights into the electrochemistry of liquid fuel oxidation reaction and oxygen reduction reaction, the catalyst and membrane synthesis and modification, electrode fabrication and optimization, and fuel cell system designs of direct liquid fuel cells. This research helps us to understand the reaction pathways, improve the reaction kinetics, enhance the fuel cell durability, and reduce the system cost.
In this Research Topic on “Advances in the Electrochemistry of Direct Liquid Fuel Cells”, we would like to provide state-of-the-art achievements, from fundamental to applications, on the electrochemistry of direct liquid fuel cells. This Research Topic will cover fundamental aspects on mathematical modeling and simulation, newly developed characterization technologies, novel catalyst and membrane synthesis and modification, and innovative fuel cell system designs.
