Ghost Of Highbury:
as the working is already clear

these are few advantages for fuel cells

-no pollutants released, only H2O formed.
-produces more energy
-lightweight
-high efficiency
-
disadvantages

a constant supply of H2 and O2 is required

generally, H2 is obtained from non-renewable sources. (cracking etc)

u can add to the disadvantages adi:
that it is quite difficult to store hydrogen for use as a fuel

Ghost Of Highbury:
yea...

thats correct!

By the way..one more for advantages..as u know..for every 4 molecules of water produced 2 are used up at the cathode..

2 molecules are passed throught the porous platinum..and can be used for drinking..

@d!_†oX!©:
yup....
bt dude..isn't that only practical for fuel cells used in aircrafts...cuz if v talk about using hydrogen in cars in daily life....do u think this point will count???just a weird question i know......
