Direct liquid fuel cells (DLFCs) have garnered significant attention due to their ease of utilization and high energy efficiency. Several DLFC technologies have been developed, including Direct Methanol Fuel Cells (DMFCs), Direct Ethanol Fuel Cells (DEFCs), Direct Formic Acid Fuel Cells (DFAFCs), Direct Glycol Fuel Cells (DGFCs), Direct Ethylene Glycol Fuel Cells (DEGFCs), Direct Dimethyl Ether Fuel Cells (DDEFCs), Direct Borohydride Fuel Cells (DBFCs), Direct Alcohol Fuel Cells (DAFCs), and Direct Hydrazine Fuel Cells (DHFCs), as alternative energy sources. This article reviews recent advancements in DLFCs, covering their working principles, the catalysts used for electrocatalytic oxidation, and single-cell performance. A particular focus is placed on the development of platinum (Pt)-based bimetallic, trimetallic, and metal oxide catalysts, which have shown significant potential as anodic electrocatalysts in DLFC technologies due to their enhanced catalytic activity, CO tolerance, and durability. The morphology and structure of these electrocatalysts are characterized using techniques such as X-ray diffraction (XRD), transmission electron microscopy (TEM), field-emission scanning electron microscopy (FESEM), and X-ray photoelectron spectroscopy (XPS).

This review also discusses the electrochemical properties and parameters that influence DLFC performance.
