Advantage of hydrogen – oxygen fuel cells |
More efficient than power stations or batteries electricity directly generated from reaction fewer places for energy to be lost as heat no moving parts so no energy lost through friction no pollutants |
|
|
Why won’t fuel cells replace conventional power stations |
Hydrogen is it gas or take some more space to store very explosive often made from either hydro Carbons or by electrolysis of water |
