ASSEMBLY GUIDE
To avoid the risk of property damage, serious injury or death:
Model No.: FCJJ-20
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. The fuel cell generates gases that are
very easily ignited. Read the instructions before use and have them ready for reference.
Warning
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 toy.

Insert the fuel cell into the rectangular slot located on the car chassis.
Place the Hydrogen outer storage cylinder into the round slot located on
the right side of the chassis.
Place the Oxygen outer storage cylinder into the round slot located on
the left side of the chassis.
Remove the cap from each tube connected
to the fuel cell. Using the syringe, inject
distilled water into the Oxygen side of the
fuel cell until the fuel cell is HALF filled with
water.
WARNING: The polymer membrane is an
important part of the proton exchange
membrane (PEM) fuel cell, it should be
prevented from drying out.
Connect the short tubes completely onto the short
H2/O2intake nozzles located on the lower sections of
both "H2" and "O2" sides of the fuel cell.
Please 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.
Use the scissors to cut two lengths of 4cm(1.5 in.) of rubber
tubing from the long rubber tubing provided in the kit.
Place the red pin into one of the 4cm tubes, and the black pin
into the other 4cm tube. Cut the remaining long tube into two
equal pieces.
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.

Connect the pre-cut tubes firmly onto the inner
storage cylinders short nozzle, connect the tubes
opposite end to the upper nozzles located on the
upper positions of both "H2" and "O2" sides of fuel
cell shown here. Make sure the tubes are connected
correctly to the corresponding sides of the fuel cell.
Connect the red and black
cables to the solar panel,
and connect the other ends
to the red and black sockets
on the fuel cell.
For solar panel: remove the cables connecting the solar
panel to the fuel cell.
Turn the switch on the battery box to “off” and remove the
cables from the cable sockets located on the fuel cell.
Keep the battery box switched to the "off" position except
during the time you are performing electrolysis.
Remove the red and black cables connected to the fuel
cell in "step 10".
Insert the banana plug cables from the car’s motor into
the red and black plugs on the fuel cell.
Make sure the colors of the plugs and cables are inserted
into plug socket of the same color as in "step 10".
The motor should begin to power the car and cause it to
start in motion. The estimated driving time on one charge
is about 3 to 5 minutes.
ALTERNATE OPTION:
Connect the red cable from
the battery pack to the
red socket on the fuel
cell and connect the
black cable to black
socket.
Switch the battery pack
to the "on" position.
Electrolysis of water should begin with oxygen
and hydrogen being produced and stored in
each storage tank.
Wait until the bubbles in the hydrogen tank start
to escape from the inner storage cylinder
located in the H2 cylinder.
(Be patient, process can take 5min – 10min)
Battery
Pack
First add water up to the "0" line.
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. Then connect the tubing to the inner
containers. Make sure there is no air trapped inside the
inner containers and the water is level to the "0" line.
Procedure for repeated gas production: 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 electroly-
sis again.
Distilled water

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 electrolyzer does not produce hydrogen and/or oxygen.
Solution:
a. Check whether the wires are appropriately connected, and whether there are any loose connec-
tions. The fuel cell could be completely destroyed if the red wire of the battery pack is connected to the
black jack 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.
