Q.3
In a fuel cell based on the oxidation of methane, the equation for the anode half-reaction is:CH4(g) + 2H2O(l) → CO2(g) + 8H+(aq) + 8e-The corresponding equation for the half-reaction at the cathode is
  • 2H2O(l) + 4e- → 4H+(aq) + O2(g)
  • 4H+(aq) + O2(g) → 2H2O(l)
  • 2H2O(l) → 4H+(aq) + O2 (g) + 4e-
  • 4H+(aq) + O2(g) + 4e- → 2H2O(l)
Q.4
A fuel cell currently under development for powering small electronic devices is based on the reaction of methanol and oxygen using an acidic electrolyte. The reductant in the cell reaction and the half-reaction at the anode are
  • Methanol; O2(g) + 4H+(aq) + 4e- → 2H2O(l)
  • Oxygen; O2(g) + 4H+(aq) + 4e- → 2H2O(l)
  • Methanol; CH3OH(g) + H2O(l) → CO2(g) + 6H+(aq) + 6e-
  • Oxygen; CH3OH(g) + H2O(l) → CO2(g) + 6H+(aq) + 6e-
Q.5
Methane gas is used as a fuel in an acidic fuel cell. The half-equation occurring at the anode will be
  • O2(g) + 4H+(aq) + 4e- →2H2O(g)
  • CH4(g) + 2H2O(g) → CO2(g) + 8H+ (aq) + 8e-
  • CH4(g) + 4H+(g)→ CO2(g) + 4H2O(l)
  • CO2(g) + 8H+(aq) + 8e- → CH4(g) + 2H2O(g)
