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

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..

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......

wen the electrons flow anode to cathode...movement of electrons = electricity! :P

anode becomes the - terminal

and the cathode = + terminal

the water in the cars can agin be converted to hydrogen by elctrolising it
andthen that hydrogen cud be used again
is this possible???  ??? ??? ??? ??? ??? ??? ???
