Too high voltage or a short circuit can destroy the fuel cell membrane.
Do not generate electricity or hydrogen for any other purposes than those given in
the instruction manual.
Only generate or store as much hydrogen as fi ts in the fuel cell's storage cylinder
(approx. 15 ml).
Avoid continuous charging of the fuel cell.
Proper Use
The Hydro Cell Kit's fuel cell may only be used to operate fi schertechnik models.
How the Fuel Cell Works
■ A fuel cell converts the chemical
energy of a fuel (e.g. hydrogen) into
electric current (electricity). A fuel cell is
therefore not an energy store but an energy
converter.
Fuels cells are used, for example, to drive
vehicles and to supply homes with heat
and electricity.
A fuel cell consists of two electrodes
(anode and cathode), which are separated
from each other by an electrolyte mem-
brane.
The electrodes are made from metal or carbon. They are coated with a catalyst, for example,
platinum or palladium.
Inside the fuel cell, hydrogen and oxygen react to form water. This reaction produces an electric
voltage between the two electrodes which can be used, for example, to drive an electric motor.
■ The fuel cell included in the Hydro Cell Kit is a so-called reversible fuel cell. This means that
the fuel cell has the following two functions:
