• The system is intended for teaching
and demonstration purposes in schools,
universities, institutions, and companies
only.
• It may only be set up and operated by a
competent person.
• Read the Operating Instructions before
setting up the 1-Cell Rebuildable PEM
Electrolyzer Kit. Follow them during
use and keep them readily available for
reference.
• Wear protective goggles and other PPEs.
• Remove inflammable gases, vapors, and
fluids from the vicinity of electrolyzers
and fuel cells. The catalysts contained
in the system can trigger spontaneous
combustion.
• Hydrogen and oxygen are
the two main gases that are
generated by the electrolyzer
system. To prevent the
gases collecting and forming
explosive mixtures only use the system
in well-ventilated rooms. Do not obstruct
the inlet and outlet ports of the system
and prevent pressure building up inside
the cell.
• Hoses, plugs, and tanks are used for
pressure compensation. They must
not be fixed or secured with clamps,
adhesive, etc.
General Safety Precautions
• The system is not a toy. Operate the
1-Cell Rebuildable PEM Electrolyzer Kit
according to the instructions provided
in this booklet and keep the cell and the
gases produced by the electrochemical
cell out of the reach of small children.
• Unless specified otherwise, do not
short-circuit or reverse the polarity of the
terminals.
• Do not operate the system dry. Always
ensure that it contains sufficient liquid
de-ionized water or liquid distilled water
at the anode side of the electrolyzer cell.
• The system may only be operated in
a display case, which is sufficiently
ventilated at all times. The operator
is obliged to prove this by means of
appropriate measurements.
• Do not smoke near this device.
• Only use the gas storage tanks belonging
to or supplied with the system to store
the generated gases during the operation
of the electrolysis cell. Never connect
other alternatives.
• Only operate the system at room
temperature and ambient pressure.
• De-ionized water or distilled water needs
to be transferred into the anode side of
the electrolyzer cell in the liquid form or
while its temperature is in the range of
5 deg. Celsius to 60 deg. Celsius. In the
case of using warmed liquid water, the
user needs to use the proper PPE.
