1 Answer

Answer :

Fuel cell- Fuel cell is a electrochemical cell which converts the chemical energy of fuels directly into electrical energy by an electrochemical process in which the fuel is oxidized at the anode.

Advanteges:-

1. High efficiency of energy conversion (75 to 82.8%) from chemical energy to electrical energy.

2. No emission of gases & pollutants within permissible limits.

3. Fuel cells offer excellent method for efficient use of fossil fuels.

4. H2 – O2 systems produce drinking water of potable quality.

5. Low noise pollution & low thermal pollution.

6. Modular & hence parts are exchangeable.

7. Low maintenance costs.

8. Fast start up time of low temperature systems.

9. The regenerative H2 – O2 system is an energy storage system for space applications.

10. Low cost fuels can be used with high temperature systems.

11. The regeneration of heat will increase the efficiency of high temperature systems.

12. Fuel cells are suitable for future nuclear solar hydrogen economy.

13. Hydrogen & air electrodes are useful in other battery systems. e.g. Ni – Hydrogen, zinc – air, aluminium – air etc.

14. Saves fossil fuels

15. Fuel cell automotive batteries can render electric vehicles efficient & refillable
