“…In general, electrocatalytic materials for fuel oxidation or oxygen reduction can be divided into three different types: abiotic, hybrid, and biological (Figure ). Abiotic electrocatalysts usually use inorganic materials such as metals, e.g., Au/Pani, Ni phosphate, or based on nanoporous multicomponents. , The use of abiotic catalysts has advantages, such as a complete fuel oxidation with a greater generation of electrons and therefore output current, a higher catalytic rate, and a higher percentage of fuel utilization (FU). The main disadvantages are their limited activity and selectivity as well as deactivation in certain conditions such as pH, byproducts, and others …”

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.

The urgent demand for designing highly efficient electrocatalysts for ethanol oxidation reaction (EOR) with elevated C1 selectivity, robust anti‐poisoning capability, and high mass activity presents a formidable challenge. Herein, a novel two‐dimentional (2D) high‐entropy PdRhFeCoMo metallene (PdRhFeCoMo HEM) electrocatalyst is successfully synthesized via a mild one‐step solvothermal method. The PdRhFeCoMo HEM, characterized by intentionally designed multi‐metallic ensembles and ultra‐thin graphene‐like structures, delivers an impressive mass activity of 7.47 A mgPd+Rh−1 and specific activity of 25.5 mA cm−2. Furthermore, it can retain a mass activity of 0.56 A mgPd+Rh−1 after undergoing 20000 s of continuous testing, demonstrating outstanding resistance to poisoning. More significantly, the PdRhFeCoMo HEM demonstrates an elevated capacity for C─C bond cleavage with a superior C1 selectivity of up to 84.12%. In situ spectroscopy analysis, combined with theoretical calculations, reveals that the deliberate design of components and structures effectively regulate the electronic properties of the Pd site, thereby enhancing the adsorption of reactant and reducing the reaction barrier of the C1 pathway. Finally, a flexible solid‐state ethanol fuel cell assembled by PdRhFeCoMo HEM presents a maximum power density of 20.1 mW cm−2 and can operate continuously by repeatedly adding ethanol fuel.

Recently, direct ethanol fuel cells (DEFCs) have been attaining a crucial role in energy resources and transportable devices. Many of the researchers in DEFCs has begin to engage considerable focus due to their high electrocatalytic activity, enormous stability, portability, and inexpensive. In this study, we present an anchoring of bimetallic Pd‐Cu nanoparticles supported ZIF‐67 catalyst (Pd‐Cu@ZIF‐67) for high‐performance electro‐oxidation of ethanol for direct alcohol fuel cells (DAFCs) applications. Structural, morphological, and elemental composition of the proposed catalyst were examined by using UV–vis spectroscopy, XRD, FE‐SEM, and EDX. Further, the electrochemical properties of Pd‐Cu@ZIF‐67 catalyst for ethanol oxidation in basic media were explored by using various electrochemical techniques. According to the results, the suggested catalyst showed maximum ECSA (128.7 m2g−1), higher current density (894.06 mA cm−2), durability (750s), and improved long‐term stability (230 cycles) than the other controlled catalysts towards ethanol oxidation reaction. This enhanced of the Pd‐Cu@ZIF‐67 catalyst is to the synergistic effects of Pd‐Cu nanoparticles and outstanding support material (ZIF‐67). These findings highly suggest the Pd‐Cu@ZIF‐67 catalyst as an anodic potential material in fuel cell applications.
