Cells and Batteries
In Non-rechargeable cells and batteries, the chemical reactions stop when one of the reactants has been used up. E.g Alkaline batteries
In rechargeable cells and batteries can be recharged because the chemical reactions are reversed when an external electrical current is supplied. Forcing the reaction the other way, therefore the electrons
Hydrogen Fuel Cells
At the Anode (positive), the Hydrogen oxides and produces Hydrogen ions. The electrons move along the circuit
At the Cathode (negative), the Oxygen reduces and gains the electrons creating the oxygen ions
