Electrolyzers can also be used to supply the PEM fuel cells with hydrogen and oxygen. Any type
of electrolyzer may be used, but those employing alkali, acid or membrane electrolytes are
generally employed. For safety reasons, absorption bottles should always be connected between
the cell and electrolyzers employing alkali or acid electrolyte.
To avoid any problems, use equipment from the H-TEC Education product catalog for gas
production. Should H-TEC Education equipment not be employed, the quality of the gases
generated must be monitored carefully. H-TEC Education assumes no responsibility for damage
or injury in such cases.

An oxygen supply is not essential for use of the H-TEC Education PEMFC Kit. In the absence of
an oxygen supply, the cell operates as an air-breathing fuel cell. It obtains sufficient oxygen from
the atmosphere by diffusion and convection. In this operating mode, however, full power is not
reached. To increase the power, unscrew the fittings on the oxygen side (Figures A & B).
