Direct methanol fuel cells or DMFCs are a subcategory of proton-exchange membrane fuel cells in which methanol is used as the fuel and a special proton-conducting polymer as the membrane (PEM). Their main advantage is low temperature operation and the ease of transport of methanol, an energy-dense yet reasonably stable liquid at all ...
Demonstration model of a direct methanol fuel cell (black layered cube) in its enclosure Scheme of a proton-conducting fuel cell. A fuel cell is an electrochemical cell that converts the chemical energy of a fuel (often hydrogen) and an oxidizing agent (often oxygen) [1] into electricity through a pair of redox reactions. [2]
Methanol is used as fuel in fuel cells. Typically Reformed Methanol Fuel Cell (RMFC) or Direct Methanol Fuel Cell (DMFC) is used. Mobile and stationary applications are typical for methanol fuel cells such as backup power generation, power plant generation, emergency power supply, auxiliary power unit (APU) and battery range extension (electric ...
SFC Energy is a manufacturer of direct methanol and hydrogen fuel cells based in Brunnthal near Munich. The company also develops solutions [buzzword] for off-grid and stationary power generation and distribution. This also includes the production of voltage converters and switching power supplies. [1]
Oorja Fuel Cells (Oorja Protonics Inc) is an energy company that designs, manufactures, and commercializes direct methanol fuel cells for use in the logistics, automotive, distributed generation (micro-grid), and telecommunication industries. Oorja develops direct methanol fuel cells ranging in power from 0.5 to 100 kilowatts.

Direct methanol fuel cells (DMFC's), for example, use methanol as the reactant instead of first using reformation to produce hydrogen. Although DMFC's are not very efficient (~25%), [ 3 ] they are energy dense which means that they are quite suitable for portable power applications.
For the alternative energy market, Viaspace subsidiary Direct Methanol Fuel Cell Corporation develops and manufactures disposable fuel cartridges for fuel cell powered electronic devices such as notebook computers, mobile phones and military systems. [23] [24] Caltech and USC are equity shareholders in DMFCC and will receive royalties on any ...
