A fuel cell works on the same principle as a battery but is continually fed with fuel. In one fuel cell, methanol enters on one side of the unit, and air enters on the other side both circulate past electrodes, and a chemical reaction occurs that produces electricity plus carbon dioxide and water as byproducts. Which chemical reaction equation best represents the reaction that occurs in this fuel cell?

a. CH3OH+O2 -->CO2+H2O

b. CH3OH-->CO2+H2O

c. CH3OH-->CH3+OH

d. CH3OH-->CH2+H2O

e. 2CH3OH+3O2-->2CO2+4H2O
