Pem fuel cell technology.
Direct methanol fuel cell advantages and disadvantages.
Because it is such a high energy resource nasa has used liquid hydrogen as a fuel since the 1970s.
Methanol is made from non renewable fossil fuels.
Direct methanol fuel cell dmfc is considered as a highly promising power source.
6 disadvantages issues in dmfc.
By way of comparison.
Methanol is very toxic and highly flammable.
Advantages of direct methanol fuel cell.
Low efficiency because methanol can pass through the available membrane materials.
Hydrogen is very difficult to deal with.
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.
List of the advantages of hydrogen fuel cells.
Today methanol fuel cells produce only limited power so they can t power vehicles but they are ideal for consumer goods e g.
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.
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.
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.
