Horizon FCJJ-16 Folheto

Assembly of the Small Electric Fan:

Connect the small round white 

adapter to the motor axis. Connect 

the fan blade to the adapter.

Connect the motor to the reversible fuel cell 

using the cables as shown. The motor should 

begin to turn and consume the hydrogen and 

oxygen gases stored in the cylinders. The fan 

may need to be flicked with your finger to start.

Connect the solar panel to the small 

motor with fan blade using the cables 

as shown. The motor should begin to 

turn if there is sufficient sunlight 

available. The fan may need to be 

flicked with your finger to start.

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 connections. 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 motor does not run 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 to purge out impure gases. You should then see the motor 

begin to turn 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.

Make sure the switch on the battery box is in the "off" position 

before you place the batteries into the box.

WARNING: If the cable is short circuited the batteries inside could 

become hot and potentially cause burns, melting of parts, or 

create risk of fire.

Note: Battery’s energy may be consumed after 4-5 times of use. 

Make sure to connect the black cable to the black plug, the red 

cable to the red plug on the fuel cell.

Please remove the screw from cover of battery box using a 

screw driver. Push and slide the cover and open the battery box. 

Try NOT to touch the cables when you open the cover. 

Place two AA batteries as indicated.

Push and slide the battery box cover to closed position and 

screw fightly into place using screw driver.
