Q. Which of the following is/are the advantages of Hydrogen Fuel Cell?
1.It is completely environment friendly with no tailpipe emissions other than water.
2.Operation times of fuel cells are longer than those of batteries.
3.Since Hydrogen is the most abundant element in the Universe, it is easy to extract and create fuel cells.
Select the correct answer using the codes given below;
Answer: B
Notes:
Statements 1 and 2 are correct: Hydrogen Fuel Cell is completely environment friendly with no tailpipe emissions other than water and Operation times of fuel cells are longer than those of batteries.
Statement 3 is incorrect: Despite being the most abundant element in the Universe, hydrogen does not exist on its own. So, hydrogen needs to be extracted from water via electrolysis or separated from carbon fossil fuels. Both of these processes require a significant amount of energy to achieve. This energy can be more than that gained from the hydrogen itself as well as being expensive.
