Question
What is the overall reaction that occurs in a hydrogen fuel cell?
Answer
The overall reaction in a hydrogen fuel cell involves the oxidation of hydrogen gas (H2) to produce water (H2O).
Explanation
This question tests the student's understanding of the chemical processes occurring in hydrogen fuel cells, specifically the conversion of hydrogen to water, which is a fundamental aspect of fuel cell technology.
Common mistake
Confusion about oxidation
Students often confuse oxidation with reduction, thinking that oxidation means the addition of oxygen rather than the loss of electrons.
Remember that oxidation involves the loss of electrons, while reduction involves the gain of electrons. In the context of a hydrogen fuel cell, hydrogen is oxidized as it loses electrons to form water.
