Question 2

Shown below are the reactions occurring in the direct methanol fuel cell (DMFC).

I.2 CH3OH(aq) + 2 H2O(l) → 2 CO2(g) +12 H+(aq) +12 e-
II.3 O2(g) + 12 H+(aq) + 12 e- → 6 H2O(l)
Overall2 CH3OH(aq) + 3 O2(g) → 2 CO2(g) + 4 H2O(l)

Which is the anode reaction, and what is being oxidized in the overall reaction?
