Active Direct Methanol Fuel Cells (ADMFCs) have been explored with continuous interest as potentially powerful low-temperature energy conversion technology in portable and distributed power supply systems. The current study offers an extensive analysis of recent progress, outstanding challenges, and future trends in ADMFC technology through the rational integration of material-related progress, system-related aspects, along with bibliometric analysis. According to the findings, notable breakthroughs in this area have been achieved through rational design in the use of advanced nano-structural electrocatalysts, as well as support materials that play a very significant role in improving methanol oxidation reaction (MOR) activity through the rational use of carbon support materials, such as carbon nanotubes, mesoporous carbon nanofibers, reduced graphene oxide, along with new carbon-free support materials like MXenes. Novel combinations of catalyst synthesis are useful in optimizing metal support interactions in improving MOR activity through bimetallic/multiphase catalyst concepts, rational use of metal loading without sacrificing activity, along synergism in improving catalyst activity through support effects. According to the findings, advances in proton exchange membranes, especially with Nafion® modifications, have shown a reduction in methanol crossover without compromising proton conductivity, thus improving the performance of single cells and stacks. Research in ADMFCs seems to be heading in the right direction, focusing on optimizing catalysts, membranes, and design. However, challenges remain in taking the cell from bench to industry, including catalyst stability and integration. Further research, including theoretical studies, will provide valuable platforms that will eventually establish the applications of DMFCs that can be offered through an ADMFC. • ADMFC research shows 9.25% annual growth (2000–2025). • Nine research clusters identified linking materials and systems. • Pt-based nanocatalysts and advanced supports dominate activity gains. • Durability and methanol crossover remain primary commercialization barriers.
