Fuel Cells and Their Advantages
Fuel cells produce electrical energy using a reaction between an external fuel source (often hydrogen) and oxygen. The fuel is added to the cell and then there is a constant supply of oxygen. The fuel is oxidised and this creates a voltage. Advantages of fuel cells include:

High efficiency

Less pollution than traditional methods

Compact and lightweight

Reliable
- The absence of moving parts means they are reliable.
