Function and Applications

For a clear demonstration of the use of hydrogen energy. The car has a blackly coated plate and is equipped with a reversible PEM fuel cell and two gas tanks for hydrogen and oxygen. Because the components are fixed on magnetic base plates they stick tight on the plate of the car during the experiments. The car has an electrical motor with a gear and a changeover switch for loading and driving operation. Only distilled water is needed for the filling of the gas tanks.

The fuel cell can be loaded with a solar module. All electric connections occur via 2-mm-plugs and/or sockets.

Benfits

• possible for driving also outside of the classroom, since for the "loading" of the gas tanks a solar battery is on hand
• solar module on magnetic base plate which can be set up under 3 different angles
• usable also on quantitative experiments
•  manual with detailed experimental instructions and additional information
