In this study, I will try to create a basic fuel cell using salt water, batteries, and platinum wire. I will fill a glass with water, and charge it through the platinum wires. I will then, after a certain period of time, disconnect the batteries from the water and connect them to a multimeter, and measure the voltage of the water and the time it takes for the electricity to discharge.
Hypothesis:
If I apply an electrical charge to a water solution, I can create a simple fuel cell which will store an electrical charge.
Dependent variables
The amount of voltage exhibited in the water solution
The speed at which the charge dissipates
Independent variables
The solution of salt in the water,
The amperage and voltage of the applied charge
The material of the cathode and anode
