Producing electric energy
As soon as there is hydrogen and oxygen in the storage cylinders, they react with each other
and an electric voltage of 0.5 to 0.9 V is produced at the jacks. The fuel cell supplies a 600 mA
current and has a nominal power of 300 mW.
Experiment:
Connect the motor in the Profi Oeco Energy kit (alternatively: Profi Oeco Tech)
(Item # 69205) to the jacks of the fuel cell (see Fig. 3, on page 3).
What do you see?
The motor is rotating. It is driven by the electrical energy generated by the fuel cell.
Shutting down/storing the fuel cell
The fuel cell should not be stored fi lled with water.
Therefore, after you have fi nished your experiments, remove the plugs from the fuel cell and
pour out the water. Shake the fuel cell to empty it completely. Then leave it to dry.
Notes on environmental protection:
Do not put the electrical and electronic components of this construction set such as motors,
lamps and sensors in the household waste. At the end of their service life, hand them in to a
collection point for the recycling of electrical and electronic devices.
The symbol on the product, packaging or the instructions indicates this.
Liability
Liability on the part of fi schertechnik GmbH for damages, which resulted from the fact that the
kit was not used in accordance with instructions, is excluded.
