Advances in microfluidic electrochemical fuel cells in recent years

Abstract

Microfluidic fuel cells (MFFCs) are performing increasingly important roles in production and life, such as electronic products, sensors and real-time equipment. The microfluidic electrochemical fuel cell (MFEFC) is a significant type of MFFC that has attracted recent global attention. Compared to the other two types, biofuel cells (MFBFCs) and photocatalytic fuel cells (MFPFCs), MFEFCs can be used in a broader range of applications and are less susceptible to external environment. This paper mainly discusses the recent progress of MFEFCs, including catalyst, fuel, electrode, oxidant, design, fabrication, model and performance. The paper summarized the latest research results and practical applications through the above aspects. The authors sincerely hope that this paper will be useful to researchers in the field. Finally, we summarize the article and outline the potential future development and applications of MFEFCs.
