Name 3 advantages of using hydrogen- Oxygen fuel cells
1) they're more efficient than power stations or batteries at producing energy
2) Because there's not many stages there's chance for energy to be lost through heat or friction
3) They don't produce any pollutants.
7 of 8
Disadvantages of Hydrogen- Oxygen fuel cells:
1)Hydrogen takes up more space to store than petrol because it's a gas.
2) Hydrogen is hard to store safely because it is very explosive.
3)Hydrogen fuel is produced using fossil fuels/ more energy.
