A fuel cell is

Answer»

the voltaic CELLS in which discontinuous supply of fuels are send at anode to give oxidation
the voltaic cell in which fuels such as : `CH_(4) , H_(2) , CO` are USED up at anode
it involves the reactions of `H_(2) - O_(2)` FUEL cell such as
Cathode : `2 H_(2) + 4OH^(-) to 4 H_(2) O(l) + 4e`
Anode : `O_(2) + 2 H_(2)O (l) + 4e to 4 OH^(-)`
the efficiency of a `H_(2) - O_(2)` fuel cell is very low

SOLUTION :`CH_(4) , H_(2) , CO` are used fuel .
