the two half-reactions that are used in the direct methanol fuel cell are shown below.

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