What advantage do the fuel cells have over primary and secondary batteries?

Text Solution

Verified by Experts

Primary batteries contain limited amounts of reactants. These cells become dead when the reactants are consumed. Secondary batteries can be recharged but take a long time for recharging. Fuel cells can be run continuously so long as the reactants are supplied and the products are removed continuously.
