Sample MCQs (with Answers and Explanations):
Q1. What is the main product formed in a hydrogen-oxygen fuel cell?
A) Carbon dioxide B) Water C) Hydrogen peroxide D) Methane
Answer: B
Explanation: In a hydrogen-oxygen fuel cell, hydrogen reacts with oxygen to form water, releasing electrical energy in the process.
Q2. Which metal is commonly used as a catalyst in hydrogen fuel cells?
A) Iron B) Platinum C) Nickel D) Copper
Answer: B
Explanation: Platinum acts as an efficient catalyst for both the oxidation of hydrogen and the reduction of oxygen in fuel cells.
Q3. “Green Hydrogen” is produced by which method?
A) Coal gasification B) Steam methane reforming C) Electrolysis using renewable energy D) Thermal cracking
Answer: C
Explanation: Green hydrogen is obtained through electrolysis of water powered by renewable energy sources like solar or wind.
Q4. What is the main advantage of using fuel cells over traditional combustion engines?
A) Higher pollution B) Lower efficiency C) Direct conversion of chemical to electrical energy D) Need for fossil fuels
Answer: C
Explanation: Fuel cells convert chemical energy directly into electrical energy with high efficiency and minimal pollution.
Q5. Which type of fuel cell operates at high temperatures and can reform hydrocarbons internally?
A) PEMFC B) SOFC C) AFC D) PAFC
Answer: B
Explanation: Solid Oxide Fuel Cells (SOFCs) operate at 600–1000°C and can reform hydrocarbon fuels directly, making them versatile.
