Fuel Cell kit
How does a fuel cell work? How can you produce hydrogen with it? The Fuel Cell kit imparts
knowledge on all aspects of this exciting topic. With the fuel cell and the additional solar
module, interesting additional models can be built in conjunction with the Profi Oeco Energy kit.
The didactic activity booklet in the Profi Oeco Energy kit provides help. All of your questions are
answered.
Important instructions on use of the Fuel Cell kit
The Fuel Cell Kit is an extension kit. You will also need the Profi Oeco Energy kit (Item # 520400)
to operate the fuel cell and to perform the experiments described in this instruction manual.
Alternatively, you can also use the Profi Oeco Tech kit (Item # 505284).
Advice for supervising adults

This experiments kit is only intended for use by children over the age of 10 years.

The instructions should enable adults to assess the experiment's suitability for the
child concerned.
Safety rules

Read these instructions before starting the experiment, follow them and keep them
ready to hand.

Keep the experiments kit out of reach of small children.

Do not put wires into the electrical outlet.

Warning: Do not remove the protective diode between the connections of the fuel
cell! It prevents irreparable damage to the fuel cell if a short circuit occurs between
the positive pole (red) and the negative pole (black) or if cables get too hot.

Do not short circuit the fuel cell (explosion hazard)!

Warning: (Connection) errors or unauthorized changes can cause temperature
increases on exposed surfaces that can exceed the allowable limits!

The fuel cell may only be operated with a direct voltage up to 3V. Never connect any
other power supplies, e. g. 9 V fi schertechnik.

Do not short circuit the contact points of the fuel cell.

Too high voltage or a short circuit can destroy the fuel cell membrane.
