There are 3 main types of electrochemical cells
- non- rechargeable
- fuel cells
The hydrogen- oxygen fuel cell
A fuel cell uses the energy created by the reaction of its fuel with oxygen to create the voltage. Reactants flow in and the products flow out while the electrolyte remains in the cell. A fuel cell will continue to work as long as the fuel and oxygen are being supplied.
Storage of hydrogen
- can be stored as a liquid under high pressure
- can be adsorbed onto the surface of a solid material
