Renewable Energy and Fuel Cell Chemistry Experiment
Experiment: Powering a Light Bulb with a Hydrogen Fuel Cell
Materials:
Hydrogen fuel cell Light bulb
Wires Baking soda
Vinegar Measuring cups and spoons
Funnel Plastic bottle
Procedure:
1. Fill the plastic bottle with equal parts baking soda and vinegar.
2. Insert the funnel into the mouth of the bottle and insert the hydrogen fuel cell.
3. Connect the wires from the fuel cell to the light bulb.
4. Observe the light bulb.
