Methanol Fuel Cells Advantages Disadvantages

High efficiency when utilizing co generation fuel cells can attain over 80 energy efficiency.

Methanol fuel cells advantages disadvantages.

The primary types of fuel cells discussed in this section are the proton exchange membrane fuel cell pemfc direct methanol. That enabled manufacturing of non fluorinated membrane for pem fuel cell applications though bringing with it advantages and disadvantages. Types working applications advantages disadvantages. Ethanol is more environmentally friendly and can be produced cheaper and with fewer carbon emissions than methanol.

The advantages of direct methanol fuel cell dmfc or any of the direct alcohol fuel cell dafc is that there is no need of complicated storage mechanism unlike the hydrogen based one. The alcohol acts as a hydrogen carrier for these fuel cells. Despite the expectations the truth is that the fuel cells present advantages and disadvantages from their use and even in the manufacture. Selection for a particular application depends on criteria such as cost.

More detailed information is available in the applications section which offers information specific to each industry. Platinum platinum ruthenium supported on carbon. Solid polymer membrane nafion. Good reliability quality of power provided does not degrade over time.

Both of these should be weighed carefully before any decision concerning methanol or ethanol should be made. Methanol is made from non renewable fossil fuels. Direct methanol fuel cells dmfcs liquid methanol water solution. Fullerene based membrane enabled operation of pemfc at.

The disadvantage is that the hydrogen used in them has to be electrolyzed from water. Fuel cells are considered to be future energy and a very promising technology. Low efficiency because methanol can pass through the available membrane materials. The most important advantage of fuel cells is that their only byproduct is water and of course discarded parts.

Methanol is very toxic and highly flammable. Fuel cells are nowadays used in power plants with reduced power less than a dozen mw. Methanol alcohol as a liquid can be easily stored and transported under ambient conditions.
