This article provides an overview of the work reported in the past decade in the field of microfluidic fuel cells.To develop appropriate research, the most commonly used electrocatalytic materials were considered and a new classification was proposed based on their nature: abiotic, hybrid, or biological. This classification allowed the authors to discern the information collected. In this sense, the types of electrocatalysts used for the oxidation of the most common fuels in different environments, such as glucose, ethanol, methanol, glycerol, and lactate, were presented. There are several phenomena presented in this article. This information gives an overview of where research is heading in the field of materials for electrocatalysis, regardless of the fuel used in the microfluidic fuel cell: the synthesis of abiotic and biological materials to obtain hybrid materials that allow the use of the best properties of each material.

“…They also discussed the effect of glucose concentration with the best cell performance at 100 mM for the Y-type and 200 mM for the cross-type. The better cell performance was obtained when the electrode was prepared with multi-walled carbon nanotubes instead of single-walled carbon nanotubes, and the enzyme was immobilized on the electrode instead of dissolved in the electrolyte [46]. Ahn et al developed a disposable paper-based membrane-free microfluidic EBFCs by preparing a composite slurry of cellulose ionic liquids and MWCNTs as carriers for GOX at the anode and Lac at the cathode [46].…”

Enzymatic biofuel cells (EBFCs) are devices that use natural enzymes as catalysts to convert chemical energy from bio-sourced fuels into electrical energy. In this review, we summarize recent research progress and applications in the field of biofuel cells based on immobilized enzymes. Specifically, we discuss how to optimize and improve the electrochemical performance and operational stability of enzymatic biofuel cells through enzyme immobilization materials, enzyme immobilization methods, electron transfer improvement on enzyme electrodes, and cell construction methods. We also cover current and future practical applications of biofuel cells based on immobilized enzymes, including implantable enzymatic biofuel cells and wearable enzymatic biofuel cells. Additionally, we present some of the issues that still need to be addressed in the field of biofuel cells based on immobilized enzymes to ensure their technical and commercial viability and sustainability.

“…[ 52 ] Besides that, biofuel cells that use glucose as fuels have been fabricated using paper‐based microfluidics. [ 53 ] The main advantage of paper‐ based devices is the capability to self‐pump electrolytes through the device for an extended period without the need for an external pump. This is particularly important in the POCT setting where low cost and portability of the power source are required.…”

While the majority of the technologies developed for energy storage are macrosized, the reactions involved in energy storage, such as diffusion, ionic transport, and surface‐based reactions, occur on the microscale. In light of this, microfluidics with the ability to manipulate such reactions and fluids on the micrometer scale has emerged as an interesting platform for the development of energy storage systems. Herein, the advances in utilizing microfluidic technologies in energy storage and release systems are reviewed in terms of four aspects. First, miniaturized microfluidic devices to store various forms of energy such as electrochemical, biochemical, and solar energy with unique architectures and enhanced performances are discussed. Second, novel energy materials with the desired geometries and characteristics that can be fabricated via microfluidic techniques are reviewed. Third, applications enabled by such microfluidic energy storage and release systems, particularly focusing on medical, environmental, and modeling purposes, are presented. Lastly, some remaining problems and challenges and possible future works in this field are suggested.
