• On the one hand, the reversible fuel cell can be used as a so-called electrolyzer, for produc-
ing hydrogen and oxygen from distilled water. This process is called electrolysis. The hydro-
gen and oxygen are stored in storage cylinders.
• On the other hand, the reversible fuel cell can be used to produce electrical energy by react-
ing the stored hydrogen with the stored oxygen.
Operating the fuel cell
Description of the fuel cell (see Fig. 1 on page 3).
1 Overfl ow chamber, hydrogen side
2 Hydrogen storage cylinder
3 Plugs for air vents
4 Oxygen storage cylinder
5 Negative jack (black)
6 Protective diode
7 Positive jack (red)
8 Overfl ow chamber, oxygen side
9 Level mark
Filling the fuel cell with distilled water
Place the fuel cell on a fl at plate.
Then remove the two plugs (3) from the ventilation ducts. Fill the two storage cylinders with
distilled water up to the level mark (9).
(See Fig. A)
Caution! Material damage possible:
Tap water and other liquids permanently damage the fuel cell membrane.
When the water is added the air in the fuel cell escapes through the air vents. Gently bang the
fuel cell on the table to let the water fl ow more easily around the membrane and the current
collecting metal plates.
Add a little bit more water, only enough to make water escape through the air vents and at the
same time for the water in the overfl ow chambers to reach up to the level mark.
