Fuel Cells

Fuel cells a type of electrochemical cell. They work on the idea that one day they could replace the inefficient conversion of fuels to heat (approx 40%)  and then electricity with a more efficient (approx 80 - 85%) and cleaner way of producing electricity. Water is produced as a 'waste' product.   They are different electrochemical cells to the ones you will have studied at IB as they are open systems - fuel (in the form of Hydrogen and Oxygen) must be ...
