Question
Chapter 20, Problem 71A
Interpretation Introduction
Interpretation:
The difference between the oxidation of hydrogen normally and in a fuel cell is to be explained.
Concept introduction:
The oxidation of hydrogen in air occurs with burning of hydrogen gas in air while the oxidation of hydrogen in fuel cell is catalytic oxidation.
Expert Solution & Answer
Answer to Problem 71A
In a fuel cell, the reaction of hydrogen and oxygen atoms takes place to form water. The process involved the release of electrons and
Explanation of Solution
Since the burning of hydrogen gas in oxygen is a combustion reaction the release of electrons is not possible but the oxidation of hydrogen in fuel cell is catalyzed therefore the electrons can be removed.
Conclusion
The main difference in the two methods of oxidation is the way in which energy is released. In fuel cell it is electrical energy while in air combustion it is heat energy.
