Abstract: The Direct Methanol Fuel Cell (DMFC) has been designed from the start to be appropriate for a wide range of appliances, including stationary and portable electrical applications, since it is regarded as a particularly promising energy source in renewable energies. It uses polymer electrolyte membrane (PEM) fuel cell technology for its ion or proton conducting electrolyte. Their key benefit is the simplicity with which methanol fuel and energy-densifying stable liquid may be transported in all climatic circumstances. Other benefits include cheaper fuel production costs, less flammability risk, and enhanced energy security and availability. It emits hydrogen and carbon dioxide but no sulphur, nitrogen, or other hazardous gases. This review paper highlights advancements in DMFC technology from its inception to the present day, with the ultimate goal of improving overall DMFC performance by addressing issues such as performance influence on operating temperature and pressure parameters; stacking; methanol and water cross-over; current collectors, optimization of gaskets, supporting plates, cathode channel configuration; experiments on portable power supply sources, and multi anodes over the last 15 years. It also identifies research needs for future efforts.
