Question
- A. fuel cell: correct Unit 4.5 answer for Fuel cells
- B. Incorrect exam-check: gives a memorised phrase without subtopic detail
- C. Incorrect exam-check: omits the key Energy changes vocabulary
- D. Incorrect exam-check: answers a different objective from Chemical cells and fuel cells (chemistry only)
Answer
The correct option is fuel cell: correct Unit 4.5 answer for Fuel cells.
Explanation
The correct option is fuel cell: correct Unit 4.5 answer for Fuel cells. It directly supports the approved learning objective to (chemistry only) State that hydrogen can be used as the fuel in a fuel cell. This exam-check version keeps the answer anchored to Fuel cells within Chemical cells and fuel cells (chemistry only), and avoids mixing energy transfer, reaction profiles, activation energy, chemical cells, fuel cells, exothermic reactions and endothermic reactions unless the objective names them.
Common mistake
Misunderstanding Fuel Sources
Students often confuse hydrogen as a fuel with other fuels and do not recognize that hydrogen is specifically used in fuel cells.
Emphasize that hydrogen is a unique fuel for fuel cells and differentiate it from other types of fuels.
