Hold On dear reader; this could grow technical when we start talking about direct methanol fuel cells! But don’t worry; I’ll do my best to make it simple! Direct methanol fuel cells are a subcategory of proton-exchange fuel cells where the alternative fuel named methanol is not converted but fed directly to the fuel cell.
Because the methanol is fed directly into the fuel cell, complex catalytic reforming is uncalled-for and storage of methanol is much lighter than that of hydrogen because it does not exact to be done at higher pressures or low temperature because methanol is a liquid. Essentially that stands for that a direct methanol fuel cell doesn’t need the complex procedure that is required of gas, and that is a good thing!
Because of the energy density of methanol, the quantity of energy loosed by using a given volume of methanol is in order bigger than even highly compressed hydrogen. So featuring a direct methanol fuel cell can help bypass all of the procedures that are found in gas engines creating an alternative fuel vehicle much more effective when it is going on methanol.
Then Again, the efficiency of direct methanol fuel cells is small due to the high permeation of methanol through the membrane of the fuel cell. This is recognized as methanol crossing over and the dynamic behavior is slow. Some Other problems include the management of carbon dioxide that is produced at the anode.
At the present-day floor of the technology, direct methanol fuel cells are determined in the power that they can grow. However, they can still store much more energy in a smaller place. That stands for that they can produce a low quantity of power through a long period. This creates them ill-suited for powering vehicles but ideal for consumer commodities like cells, digital cameras, and laptops.
Other issue with a direct methanol fuel cell has to do with methanols chemical attributes. It is toxicant and inflammable. But there are exclusions to be made. Because direct methanol fuel cells are allowed on airplanes to power laptops along with other consumer electronic devices, they can as well be fought for to power vehicles too.
Yes, it does appear complicated when we start throwing around complicated phrases such as direct methanol fuel cell. But the reality is that these types of batteries and power generators are being in use ordinary to power small appliances with a minimum of environmental damage. Why shouldn’t we be capable to utilize the same thing to power cars?
