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.

Hydrogen peroxide has been an attractive oxidant in direct liquid fuel cells. However, hydrogen peroxide reduction reaction heavily relies on noble metalbased electrocatalysts. In this work, a carbon mat decorated with FeCoNi alloy nanoparticles (namely FeCoNi/CM) of an ultralow loading, that is, 0.146 mg cm À2 , for hydrogen peroxide reduction is designed, fabricated, and applied as a free-standing cathode in a passive alkaline-acid direct ethylene glycol fuel cell. A piece of Pd/C coated carbon cloth (1.0 mg cm À2 ) is used as the anode and a pre-treated Nafion 211 membrane as the membrane. This passive fuel cell yields a peak power density of 17.4 mW cm À2 at 23 C, which is comparable to an Au/C-based cathode (17.0 mW cm À2 ). The new electrode shows significantly enhanced mass transfer and allows a current density of 60.0 mA cm À2 , which is 1.5 times the value achieved with the Au/C-based cathode. This can be attributed to the much thinner thickness of FeCoNi/CM (50.0 μm) than Au/C-based cathode (380.0 μm). With the thinner thickness, the oxygen derived from the self-decomposition of hydrogen peroxide can be effectively removed from the cathode, which is beneficial for the transport of hydrogen peroxide to the catalyst surface. Moreover, with the use of this freestanding cathode, the passive fuel cell attains a continuous operation at a constant discharging current of 20.0 mA for more than 9 h, exceeding the 5 h achieved with the Au/C-based cathode at the same discharging current density.

Summary The requirement of expensive precious metal catalysts as electrode materials in fuel cells remains a major obstacle to commercialization. In this work, two ascorbate fuel cells are fabricated without precious metal catalysts and are operated at 60°C with an alkaline fuel stream consisting of ascorbate and NaOH. A split pH ascorbate‐peroxide fuel cell utilizing a Cu/C anode and carbon black cathode was fabricated with a Na+ conducting cation exchange membrane and operated with H2O2 in H2SO4 as the oxidant. It achieved a maximum power density of 51 mW cm−2 and an open circuit voltage of 1.05 V. This power density is comparable to previous ascorbate and ascorbic acid fuel cells that utilized precious metal catalysts (ie, Pd, Pt). Notably, the performance was achieved with simple Cu and C electrodes. For comparison, an alkaline ascorbate fuel cell was prepared that employed a Cu/C anode and ACTA cathode (FeCo/C) separated by an anion exchange membrane and used oxygen gas as the oxidant. It produced a maximum power density of 6 mW cm−2 and an open circuit voltage of 0.48 V. These ascorbate fuel cells demonstrate the opportunity to replace precious metal catalysts in order to dramatically lower the cost of fuel cell electrodes with comparable performance to counterpart ascorbate fuel cells previously employing precious metal catalysts.
