DMFC: Direct Methanol Fuel Cell

DMFC is an abbreviation of "Direct Methanol Fuel Cell". Direct-methanol fuel cells come under the secondary type of proton-exchange fuel cells in which the use of the methanol is made in the form of fuel.

DMFC Applications

  • At present, the DMFCs, which are in the process of application, are restricted to some degree in the power they are capable of generating, although they are still capable of accumulating in undersized space a lot of high energy content.
  • DMFCs are best in generating and providing power in case of smaller vehicles and supplies of customers such as forklifts, digital cameras or laptops, smart-phones, etc.
  • DMFCs are also applied in Military services. They are turned out to be a prominent application as they comprise low noise, thermal signatures, and no toxic effluent.
  • DMFCs applications consist of generated power in case of man-portable strategic device or tool, battery chargers, and independent power to analyze and guide instrumentation.

DMFC Benefits

  • In a Direct Methanol Fuel Cell in contrast to hydrogen, methanol is a lot easier to store.
  • DMFC does not require high pressures or temperatures.


  • In Direct Methanol Fuel Cell, methanol is incredibly toxic and extremely flammable.
  • Methanol used in DMFC is prepared from non-renewable fossil fuels.
  • Methanol has low efficiency for the reason that it is capable of passing through the existing accessible membrane resources.
