Answer 2

Hydrogen fuel cells have a higher energy efficiency.

Hydrogen fuel cells create less pollution.

Step-by-step explanation:

Hydrogen fuel cell is an electrochemical cell which employs hydrogen gas to produce electricity and water.In this cell chemical energy of hydrogen gas is converted into electrical energy.

Advantages of hydrogen fuel cell:

• It directly converts chemical energy into electrical energy.
• Only emission of water and little heat that is it creates less pollution.
• Much more reliable source of energy.
• Highly efficient energy resource.
• Extraction of hydrogen can be done without harming an environment than the extraction of other fossil fuels and oil which causes damage.
