Fuel Cells
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.
