HYDROCAR TECHNICAL SUPPORT
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.
