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.
Direct methanol fuel cell advantages and disadvantages.
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.
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.
Methanol is made from non renewable fossil fuels.
Methanol is very toxic and highly flammable.
Pem fuel cell technology.
Direct methanol fuel cell dmfc is considered as a highly promising power source.
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.
It offers an effective method of energy storage.
Low efficiency because methanol can pass through the available membrane materials.
6 disadvantages issues in dmfc.
Because it is such a high energy resource nasa has used liquid hydrogen as a fuel since the 1970s.
It poses a number of advantages such as a liquid fuel quick refueling low cost of methanol and the compact cell design making it suitable for various potential applications including stationary.
By way of comparison.
Advantages of direct methanol fuel cell.
Hydrogen is very difficult to deal with.
Today methanol fuel cells produce only limited power so they can t power vehicles but they are ideal for consumer goods e g.
