Which of the following is NOT true regarding the usage of hydrogen as a fuel?
- A Combustion product is ecofriendly.
- B Hydrogen gas can be easily liquefied and stored.
- C High calorific value
- D The combustible energy of hydrogen can be directly converted to electrical energy in a fuel
cell.
Answer & Solution
Correct Answer
(B) Hydrogen gas can be easily liquefied and stored.
Step-by-step Solution
Detailed explanation
(B)
Hydrogen is highly inflammable and hence storage is difficult.
Hydrogen has low critical temperature and hence not easily liquefiable.
