Horizon FCJJ-16 Folheto

Insert the reversible fuel cell, terminals on top, into the slot on the 

base. Cut 2 x 4cm length pieces of rubber tube and insert a black 

pin into the end of one tube.  Place the tube with the black pin into 

the top pin on the hydrogen side (with black terminal). Place the 

other tube firmly onto the top input nozzle on the oxygen side.

Fill the syringe with DISTILED 

water. On the red oxygen side of 

the reversible fuel cell, connect the 

syringe to the uncapped tube. Fill 

the reversible fuel cell until water 

begins to flow out of the tube.  

Attach a red plug to the oxygen 

side tube. Let settle for 3 min.  

Place inner containers into outer cylinders minding that 

the gaps are not blocked by inner plastic rims. Make sure 

the water is still level to the “0” line. If not, remove some 

water with the syringe so that water level is at “0” line. Cut 

the remaining piece of long tubing into two pieces of 

approximately 20 cm length. Connect the two pieces of 

tubing to the top nozzles on the inner containers. If the 

tubing is connected to the inner cylinders last there will be 

no air trapped inside the inner containers.

 

Connect the other end of the long tube on the hydrogen 

side to the bottom end of the black hydrogen side of the 

reversible fuel cell. Connect the other end of the long tube 

on the oxygen side to the bottom end of the red oxygen 

side of the reversible fuel cell. 

Connect the reversible fuel cell to the solar panel using 

the corresponding cables and expose to direct  sunlight. 

(Important: make sure connections 

are correct or permanent damage 

can occur.)

The system will now start to 

produce oxygen and hydrogen in 

the respective cylinders. When 

bubbles begin to surface in the 

hydrogen cylinder the cycle is 

complete. Disconnect the 

reversible fuel cell.

Procedure for repeated gas 

production: Reconnect the solar 

cell to the reversible fuel cell. 

Disconnect the small plugs from 

the tubes connected to the nozzles 

on the reversible fuel cell. This will 

allow water into the inner cylinders 

to replace the gasses and reset 

water levels to “0” line. Re-insert 

the plugs into the tubes and repeat 

electrolysis again.

Battery operation instructions:

1. The removing and inserting of batteries is to be 

conducted by the adults only. Unscrew the screw holding 

the battery pack’s cover in place using a screw driver. Once 

the screw is removed open the battery pack and take out 

the batteries using your fingers. Do not use a metal 

object.When inserting the batteries make sure that you are 

doing so with the correct polarity (the positive end of the 

battery must match up with the “+” and the negative end of 

the battery must match up with the “-” indicated on the 

battery pack), close the battery pack and secure its cover by 

tightening the screw with a screw driver.

2. Non-rechargeable batteries are not to be recharged.

3. Different types of batteries such as rechargable, alkline 

and standard batteries or new and used batteries are not to 

be mixed and should be used separately.

4. The battery pack cables are not to be inserted into an AC 

socket.

5. The supply terminals of the battery pack are not to be 

short-circuited.

6. The two spare red&black cables are not to be inserted 

into an AC socket.

7. Exhausted batteries are to be removed from the battery pack.

Warning

To avoid the risk of property damage, serious injury or 

death:
This kit should only be used by persons 12 years old 

and up, and only under the supervision of adults who 

have familiarized themselves with the safety measures 

described in the kit. Keep small children and animals 

away, as it contains small parts that could be 

swallowed. Read the instructions before use and have 

them ready for reference.
