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)
Overall 2 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?

Question

Quizplus · Accepted Answer

In a direct methanol fuel cell (DMFC), the anode reaction is where oxidation occurs, which is Reaction I. Methanol (CH3OH) is being oxidized to carbon dioxide (CO2), releasing electrons in the process. This makes CH3OH the substance being oxidized in the overall reaction.
