What are fuel cells?

Advertisement Remove all ads


The galvanic cell in which two energy of combustion of fuels is directly connected into electrical energy Called fuel cell.
Reaction of cell :
Oxidation at anode :
At anode hydrogen gas is oxidized to H2O.

\[\ce{2H2(g) + 4OH-(aq) -> 4H2O(l) + 4e-}\]

Reduction at cathode (+)
The electrons released at anode travel to cathode through the external circuit.
Here O2(g) is reduced to `"OH"-`
\[\ce{O2(g) + 2H2O(l) + 4e- -> 4OH- }\]
