With reference to ‘fuel cells’ in which hydrogen-rich fuel and oxygen are used to generate electricity. Consider the following statements:
- If pure hydrogen is used as a fuel, the fuel cell emits heat and water as by-products.
- Fuel cells can be used for powering buildings and not for small devices like laptop computers.
- Fuel cells produce electricity in the form of Alternating Current (AC).
Which of the statements given above is/are correct?
Detailed Explanation:
✅ Statement 1 – Correct: Pure hydrogen fuel cells emit only water (H₂O) and heat as by-products when hydrogen reacts with oxygen, making them a zero-emission energy source.
❌ Statement 2 – Incorrect: Fuel cells can power both large-scale applications (buildings, vehicles) and small portable devices (laptops, mobile phones). Micro fuel cells and portable fuel cells are already developed for consumer electronics.
❌ Statement 3 – Incorrect: Fuel cells produce electricity in Direct Current (DC) form, not Alternating Current (AC). An inverter is required to convert DC to AC for grid compatibility.
