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.

“…This indicates that WI was quite sensitive to the performance of the MMFC with the double-bridge structure. Tanveer and Kim et al [37] studied the influence of the bridge height on the performance of an MMFC with the single-bridge channel. They found that as the bridge height (h) increased to a critical value, the power density increased.…”

“…Tanveer and Kim [35,36] investigated the inlets located at the center of microchannels as well as microchannels supporting multiple inlets to mitigate the thickness of the diffusive mixing region and the associated ohmic and mass transfer losses to augment the performance of an MMFC. In addition, Tanveer and Kim [36,37] investigated a bridge-shaped MMFC with multiple inlets, which reduced the mixing layer thickness at the end of each channel. Shaegh et al [23] and Krishnamurthy et al [29] investigated the effects of the electrode structure and arrangement, fuel utilization, and fuel crossover on the performance of an MMFC.…”

A double-bridge shape is proposed as a novel flow channel cross-sectional shape of a membraneless microfluidic fuel cell, and its electrochemical performance was analyzed with a numerical model. A membraneless microfluidic fuel cell (MMFC) is a micro/nano-scale fuel cell with better economic and commercial viability with the elimination of the polymer electrolyte membrane. The numerical model involves the Navier–Stokes, Butler–Volmer, and mass transport equations. The results from the numerical model were validated with the experimental results for a single-bridge channel. The proposed MMFC with double-bridge flow channel shape performed better in comparison to the single-bridge channel shape. A parametric study for the double-bridge channel was performed using three sub-channel widths with the fixed total channel width and the bridge height. The performance of the MMFC varied most significantly with the variation in the width of the inner channel among the sub-channel widths, and the power density increased with this channel width because of the reduced width of the mixing layer in the inner channel. The bridge height significantly affected the performance, and at a bridge height at 90% of the channel height, a higher peak power density of 171%was achieved compared to the reference channel.

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.
