Direct Methanol Fuel Cell Advantages And Disadvantages

Methanol is made from non renewable fossil fuels.

Direct methanol fuel cell advantages and disadvantages.

It offers an effective method of energy storage. Now we are looking at the advantages and disadvantages of hydrogen fuel cells to see if they would be useful in other vehicles or situations. Hydrogen is very difficult to deal with. 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.

First it has a lower density than any other fuel compare liquid hydrogen s 70 8 g per liter with gasoline s 770 grams per liter so you need huge tanks to haul it around in. List of the advantages of hydrogen fuel cells. About 3 in mass to carry the reactant into the cell. Methanol is very toxic and highly flammable.

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. Because it is such a high energy resource nasa has used liquid hydrogen as a fuel since the 1970s. By way of comparison. Direct methanol fuel cell dmfc is considered as a highly promising power source.

6 disadvantages issues in dmfc. Today methanol fuel cells produce only limited power so they can t power vehicles but they are ideal for consumer goods e g. Advantages of direct methanol fuel cell. It must offer significant benefits as it has not only inspired the development of a type of fuel cell dedicated to its use the direct methanol fuel cell dmfc but is also becoming increasingly popular.
