Question

A fuel cell works on the same principle as a battery but is continually fed with fuel. In one fuel cell, methanol (CH3OH) 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 balanced chemical reaction equation best represents the reaction that occurs in this fuel cell?

2CH3OH + 3O2 ® 2CO2 + 4H2O

CH3OH + O2 ® CO2 + H2O

CH3OH ® CH3 + OH

CH3OH ® CH2 + H2O

CH3OH + O2 ® CO2 + H2O

CH3OH ® CH3 + OH

CH3OH ® CH2 + H2O

Explanation / Answer

Given that (CH3OH) enters on one side of the unit, and air enters on the other side.

carbon dioxide and water as byproducts.

Hence, balanced chemical reaction equation best represents the reaction that occurs in this fuel cell is

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