What is a disadvantage of the methanol fuel cell? (hint: think global warming)
Homework Answers
Reaction of Methanol fuel cell
CH3OH + 3/2 O2 = CO2 + 2H2O ( overall reaction)
Now look byproduct is CO2 gas which is one of the gas belongs to green house effect gas. Due to which the temperature of the earth is increasing . Which causes melting of glaciers and ice
If you have any query please comment
If you satisfied with the solution please like it thankxx

In a Methanol fuel cell please assume that 100 Methanol (??3??) molecules enter the anode side of a full cell and 150 oxygen (?2) molecules enter the cathode side of this same full cell. If all these molecules are utilized by the fuel cell, please calculate: 1) How many electrons (?−) propagated through the load resistance between the anode and the cathode during this process? 2) How many water molecules are produced (not counting those produced at the cathode and...
