Question

What is the one of the biggest challenges with hydrogen fuel cells?

Answer 1

Explanation:

convert the chemical energy of fuel into electrical energy is called fuel cell.

Difference between Fuel cells and Galvanic cells-

Fuel cell Galvanic cell

Converts the energy from the combustion of fuels such as etc. directly into the electrical energy.

Chemical energy of the spontaneous redox reaction is converted into the electrical energy.

It is a continuous source of energy. It is not a continuous source of energy.

It is not pollution free. It is not pollution free

There is a continuous supply of the reactants.

The supply of the reactants is not continuous.
