Part 8. Troubleshooting
1. The water levels do not drop when the gas outlet tubes on both sides of the reversible 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 1: Check whether the wires are appropriately connected, and whether there are any loose connec-
tions. The reversible fuel cell could be completely destroyed if the red wire of the battery pack is connected to
the black jack of the reversible fuel cell.
Solution 2: Make sure the batteries are inserted with the correct polarity.
Solution 3: Replace the old batteries with new one in the battery pack.
3. The water electrolysis process slows down.
Solution 1: Inject water to the oxygen side of the reversible fuel cell by using the syringe and wait for about 3
minutes.
Solution 2: Replace the old batteries with new one in the battery pack.

4. The load can not work while there is hydrogen left in the inner container.
Solution: Unplug the black pin of the short tube on the reversible fuel cell and quickly attach the pin back to the
tube (see page 21). You can see the load working well again.
5. No hydrogen is produced under the sunlight.
Solution: If the sunlight is not strong enough electricity will not be created. Use the battery pack provided to
perform the electrolysis using the reversible fuel cell.
