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 environmental conditions.
Whilst the thermodynamic theoretical energy conversion efficiency of a DMFC is 97%;[1] the currently[when?] achievable energy conversion efficiency for operational cells attains 30%[2] – 40%.[3] There is intensive research on promising approaches to increase the operational efficiency.[4]
A more efficient version of a direct fuel cell would play a key role in the theoretical use of methanol as a general energy transport medium, in the hypothesized methanol economy.
