Troubleshooting - Conrad H-racer Benutzerhandbuch

6. Troubleshooting

1. The H-racer does not move or runs slower:
a. Check to see if the balloon inside the car's storage tank is full, the wires are not touching the
wheels and the switch underneath the car chassis is at the "on" position.
b. If the balloon is empty, you must complete the steps in section 5 "Refueling and Operating", then
turn the car switch to the "on" position.
c. If the hydrogen storage cylinder's inner balloon appears to be full, unwanted gases have entered
your system. The H-racer only operates on pure hydrogen drawn from its storage tank. One quick fix
is to use your finger to lightly push in the car's refueling input valve (part D), while leaving the car
switched "on". You will notice the car will start moving again. By doing this you would have removed
some of the unwanted gases from the balloon inside the hydrogen storage cylinder.
d. If the wires are touching the wheels move them away so the wheels run freely.
2. The balloon inside the car's storage tank does not fill up:
a. Check the rubber seal securing the balloon inside the cylinder has not become dislodged.
b. Make sure all the tubes inside the car are well connected and that the output valve of the refueling
station is well connected to the input valve of the car (press the output valve tightly into the input
valve). You may want to unplug and plug the connectors once more to be sure.
c. Make sure you filled the Hydrogen Station's water tank with water (distilled water*) and waited for 5
minutes before turning it on. When it is switched on, check to see that the refueling station is
releasing small bubbles on the right hand side of the water tank.
d. If all connections are correct and bubbles are released, and the balloon still does not fill up - your
H-racer refueling system is damaged due to improper use. Do not attempt to repair or fix your
H-racer, contact support@horizonfuelcell.com
3. The bubbles are appearing slowly in the Hydrogen Station's water tank:
a. If you are using solar panels, make sure the solar panel is in direct sunlight. The solar powered
refueling process is slower than if "DC" powered. Therefore it is normal that the bubbles are
appearing more slowly in the Hydrogen Station's water tank. The standard solar cell included with the
Hydrogen Station fills the H-racer after at least 10 minutes in strong sunlight.
b. If you are using the "DC" power option and bubbles are appearing slowly, please replace the
alkaline batteries inside the Hydrogen Station with new alkaline batteries.
c.The Hydrogen Station's electrolyzer may have dried up as a result of continous use or an extended
storage period. In this case find the syringe and remove the blue connector from its tip, leaving the
flexible tube attached to the syringe. Push all the air out of the syringe. Position the flexible tube
inside the water tank, at the tip of the tube where the oxygen bubbles are released from.
Use the syringe to suck water out into the syringe container. Watch the tubes inside the refueling
station closely to make sure water is being "pumped out" into the syringe. This process hydrates the
electrolyser and facilitates hydrogen production. Once this is completed, wait 2-3 minutes before
operating the refueling station again. All should be back to normal!
Be careful not to use the refueling station continuously. Continuous use (over 20 minutes) will
damage the refueling station permanently. Turn off the refueling station immediately after the
refueling of the H-racer is complete.
*you can purchase distilled water at your local drugstore or pharmacy.

4. The bubbles are appearing from the center of the water tank:
a. Turn the refueling station switch to the off position straight away as the electrolyzer is dehydrated.
b. See troubleshooting section 3 c. for details on how to "humidify" the electrolyzer.
5. The blue LED lights do not flash and no bubbles appear in the Hydrogen Station's
water tank.
a. If you are using the included solar panel, check whether the cable connections are correct. If the
weather is cloudy or if it is dark, electricity will not be generated and the Hydrogen Station will not
operate. In this case, you must switch to DC power.
b. If you are using 2AA alkaline batteries, please check they are correctly inserted into the battery box
underneath the Hydrogen Station. If the refueling station still does not operate, the batteries may be
out of power. Please replace the batteries with new alkaline batteries.
c. See troubleshooting section 3 c. for details on how to "humidify" the electrolyzer.
6. The H-racer runs slowly and lasting for a short time, but the hydrogen
storage cylinder is full of hydrogen.
a. The fuel cell needs to be warmed up by adding water and short circuited. Follow the steps as
described in Tip 2 on page 32 to reactivate the fuel cell.
b. After you have finished using the fuel cell, it is highly recommended to place it inside the air-sealed
aluminum bag provided. This will protect the fuel cell while you are not using the H-racer.
