What is a fuel cell? Write reaction involved in H2−O2fuel cell.
An electrochemical cell in which the chemical energy of the fuel is directly converted into electrical energy is known as a Fuel cell. The Half cell reactions in Hydrogen-oxygen fuel cell as follows: Oxidation at anode: 2H2(g)+4OH−(aq)→4H2O(l)+4e−2H2(g)+4OH−(aq)→4H2O(l)+4e− Reduction at cathode: O2(g)+2H2O(l)+4e−→4OH−(aq)
