A Direct Methanol Fuel Cell (DMFC) is similar to the PEM (Proton Exchange Membrane Fuel Cell or Polymer Electrolyte Membrane) Fuel Cell that uses a proton conducting polymer membrane as an electrolyte. However, a DMFC uses methanol directly on the anode instead of Hydrogen as the fuel, which eliminates the need for a fuel reformer, and operates at approximately 100°C. The Methanol is an easier in transportation and a higher energy density than hydrogen.
