The Two Half-Reactions That Are Used in the Direct Methanol

Essay

The two half-reactions that are used in the direct methanol fuel cell are shown below.
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)
The electrode at which half-reaction I occurs is the ________ at which ________ is oxidized,and half-reaction II occurs at the ________ at which ________ is reduced.
