Methanol Fuel Cell

Direct methanol fuel cell is one of the best candidates for micro fuel cell applications such as mobile phone personal computer and electronic gadgets.

Methanol fuel cell.

During operation the cell consumes water at the anode and then produces it at the cathode so water must. From start up smart fuel cell gmbh to international successful german mittelstand provider of hybrid power solutions with hydrogen and methanol fuel cells more than 45 000 fuel cells sold worldwide a total of 6 5 million kwh of environmentally friendly electricity saving 3 600 tons of co2. Reformed methanol fuel cell rmfc or indirect methanol fuel cell imfc systems are a subcategory of proton exchange fuel cells where the fuel methanol ch 3 oh is reformed before being fed into the fuel cell rmfc systems offer advantages over direct methanol fuel cell dmfc systems including higher efficiency smaller cell stacks no water management better operation at low. The cell uses a polymer membrane electrode similar to that used in the proton exchange membrane fuel cell.

The direct methanol fuel cell dmfc has been considered as the ideal fuel cell system since it produces electric power by the direct conversion of the methanol fuel at the fuel cell anode. Proton exchange membrane fuel cells pemfcs and direct methanol fuel cells dmfcs are promising power sources from portable electronic devices to vehicles. Fuel cells use hydrogen as a fuel to produce clean and efficient electricity that can power cars trucks buses ships cell phone towers homes and businesses. About 3 in mass to carry the reactant into the cell.

The direct methanol fuel cell is a low temperature cell that is capable of operating with liquid methanol supplied directly to its anode. 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. The high cost issue of these low temperature fuel cells can be primarily addressed by using platinum group metal pgm free oxygen reduction reaction orr catalysts in particular atomically dispersed metal nitrogen carbon m n c. Common operating temperatures are in the range 50 120 c where high temperatures are usually pressurized dmfcs themselves are more efficient at high temperatures and.

Although there is considerable development work being done on the catalyst especially to reduce the amount of catalyst and the mea and the handling of high concentrations of methanol without mea crossover it still lacks a high power density.
