“…Alonso Moreno Zuria et al studied the effect of electrode arrangement on MFEFCs performance by numerical simulation. 121 When the anode and cathode were arranged in parallel, both MFEFC performance and fuel utilization were enhanced greatly. The reason was that the layout reduced both the distance between the electrodes and the resistance of MFEFCs.…”

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.

“…A variety of fuel cells are being developed to convert chemical energy into electrical energy. [1][2][3][4][5][6][7][8][9] Fuel cells have no emissions, better energy density, 10 and could supply power in applications ranging from miniature electronic devices to big plants. Most fuel cells use a proton exchange membrane (PEM) to carry out the electrochemical reactions.…”

A novel flow channel configuration of a membraneless microfluidic fuel cell (MMFC) with porous flow-through electrodes was investigated numerically. A numerical model was developed for the electrochemical analysis and validated using experimental data. The physical phenomena involved in the microfluidic fuel cell including the flow of the vanadium redox couple (oxidant and fuel), mass transport, and electrochemical reaction kinetics at the electrodes are coupled in the numerical model. Considering the impact of diffusive mixing zone on the performance of MMFC, a hollow structure is proposed for the cross-section of the central flow channel. The hollow structure showed a peak power density, which is higher than those of the H-shaped, simple bridgeshaped, and rectangular channels by 6%, 18%, and 82%, respectively. Highlights• Numerical model of an MMFC with flow-through porous electrodes was validated using experimental data.• MMFC with flow through electrodes was investigated for various channel configurations.• Hollow flow channel coupled with porous electrodes performed best at critical height ratio.

“…10 The membraneless feature of MFC also brings great operation flexibility in terms of reactant concentration, reactant selection, electrolyte flow rate, and pH of supporting electrolyte. 11 Consequently, numerous MFCs have been demonstrated using different fuel-oxidant combinations and various electrolyte concentrations and ratios, which facilitates the MFCs to achieve higher cell performances. [12][13][14] Nevertheless, due to the inherent dimension restriction, the output powers of MFCs are still very low (around the milliwatt or microwatt level) and remain as a bottleneck for their practical applications.…”
