Background Information Scientific Definitions: - 2 electrodes: anode(+) & cathode (-) - Electrolyte (carries charges) - Catalyst (speeds reaction) Fuel Cell Basics - needs a fuel to work - needs many cells
What is a Fuel Cell? Chemical reaction generates voltage Unlike battery- no recharge chemical reaction = electrons flow→circuit; supply load with energy
How does it work? Hydrogen enters and loses electron at anode Proton →electrolyte, electron →circuit O 2 enters at cathode, O 2 + p + + e - = H 2 O
How does it Work?-Continued Only emission =(H 2 O) water vapour
