Super capacitor powered car
What you need:
a. Car Frame
b. Capacitor (energy storage)
c. Wires
d. Battery pack
e. Hand generator (dynamo)
Important notes :
1. You can set the wheels position using the steering on the front of the car.
2. Ensure that the electrical connections under the car are tight.
3. Do not load the capacitor if wires are connected in the wrong sense, otherwise you will broke the
capacitor.
4. The power stored is consequent, the car will start really fast so ensure there is free space in front of the
car before connecting it.
Load the capacitor
Step 1. Open the battery pack and insert 2 AA batteries with the correct polarity.
Step 2. Using the wires, connect the capacitor to the battery pack and ensure to respect the polarity shown
by the color code. Let the capacitor load during 1 min and then disconnect the capacitor. You can also use
the hand generator to realize this operation. Connect it and ensure to respect the color code, turn the
handle clockwise during 1 min with the velocity of two revolutions per second.
WARNING: 1. You are NOT allowed to rotate the arm anti-clockwise to charge the super capacitor.
Otherwise the super capacitor will be damaged by the countercurrent.
2. DO NOT crank the arm too fast otherwise the hand crank generator could be easily broken by the
strong force.

Step 3. Connect the engine wires which exceed the bottom of the car, to the closest red and black plugs.
Step 4. Using the two remaining wires, connect the fuel cell to the car frame. Make sure you respect the
polarity shown by the color code. The car will run until there is no more hydrogen in the inner gas tank.

Troubleshooting
You will also need the following items
(not included in this kit):
- AA batteries
1. The water levels do not drop when the gas outlet tubes on both sides of the fuel cell are unplugged.
Solution:
Check whether the holes on the wall of the inner cylinder are blocked. If so, turn the inner cylinder until water
enters the holes and fills up the inner cylinder.
2. The reversible fuel cell does not produce hydrogen and/or oxygen.
Solution:
a. Check whether the wires are appropriately connected, and whether there are any loose connections. The
fuel cell could be completely destroyed if the red wire of the battery pack is connected to the black socket of
the fuel cell.
b. Check whether the switch of the battery pack is in the “on” position.
3. The water electrolysis process slows down.
Solution:
a. Add water to the oxygen side of the fuel cell and wait for about 5 minutes.
b. Replace old AA batteries with new AA batteries inside the battery pack.
4. The car stops moving while there is still hydrogen left inside the tanks.
Solution:
a. Purge the gases and perform water electrolysis for 4-5 minutes. Unplug the hydrogen gas outlet tube and
oxygen gas tubes to purge the gases. Perform water electrolysis again until the hydrogen tank is filled, and
connect the motor to the fuel cell. If the problem persists, go to the next step.
b. Let the water electrolysis process last about 10 minutes to consume the residual water. To push water out
of the fuel cell, purge the gases. Perform water electrolysis once more until the hydrogen tank is filled, then
connect the motor to the fuel cell.
