This paper aims to review the different types of liquid fuels directly used in fuel cells and identify their properties challenges and applications.

Direct methanol fuel cell is a modified version of.

Hello fellow wikipedians i have just modified 2 external links on direct methanol fuel cell. I made the following changes. Among the fuel cell types direct methanol fuel cell dmfc is the most feasible candidate to li ion batteries as the power source for portable applications in the future and is now under rapid development this is mainly because of its high energy density simple structure and rapid operation. About 3 in mass to carry the reactant into the cell.

In contrast to indirect methanol fuel cells where methanol is reacted to hydrogen by steam reforming dmfcs use a methanol solution usually around 1m i e. Passive direct methanol fuel cells dmfcs are potentially applicable as portable power sources due to their high energy density low pollution simple structural design and easy re fueling however at present dmfcs face critical technical problems that hamper their practical applications including low power density slow reaction kinetics of methanol oxidation and. An attempt by matthew feickert to build an operational direct methanol fuel cell for his independent study in chemistry during the 1st semester for the 2006. Direct methanol fuel cells are prepared using pa pbi sio 2 composite membranes.

The hydrophilic pvdf porous membrane with a 450 nm inner pore size was chosen as the supporting structure. Pristine sio2 with a uniform particle size of 95 110 nm was synthesized and functionalized with nh2 and cooh. Tian sheng ab xiao lin a zhao yang chen c p. Above 205 c the increase in power density with temperature is 208 mwcm 2 100 c.
