Answer

Fuel cells have several advantages over lead storage batteries. First of all, while lead storage batteries have a limited time because the electrodes lose lead sulfate and must be replaced eventually, fuel cells have renewable electrodes. Fuel cells do not have to be recharged. Fuel cells also can be designed to emit no air pollutants. Lastly, generally speaking, fuel cells are very cost-effective.
