This part of IEC 62282 covers construction, marking and test requirements for portable fuel
cell power systems. These fuel cell systems are movable and not fastened or otherwise
secured to a specific location. The purpose of the portable fuel cell power system is to
produce electrical power.

This standard applies to a.c. and d.c. type portable fuel cell power systems, with a rated
output voltage not exceeding 600 V a.c., or 850 V d.c. for indoor and outdoor use. These
portable fuel cell power systems are not to be used in hazardous locations as defined by
IEV 426-03-01 unless additional protective measures are added in accordance with
IEC 60079-0.

This standard does not apply to portable fuel cell power systems that are
a) permanently connected (hard wired) to the electrical distribution system,
b) permanently connected to a utility fuel distribution system,
c) exporting power to the grid,
d) for propulsion of road vehicles,
e) intended to be used on board passenger aircraft.

Fuel cells that provide battery charging for hybrid vehicles where the battery provides power
and energy for propulsion of the vehicle are not included in the scope of this standard.

The following fuels and fuel feedstocks are considered within the scope of this standard:
• natural gas;
• liquefied petroleum gas, such as propane and butane;
• liquid alcohols, for example methanol, ethanol;
• gasoline;
• diesel;
• kerosene;
• hydrogen;
• metals (e.g. Mg, Al or Zn) or metal alloys immersed in electrolyte (e.g. aqueous solutions
of salts or alkali) in air or oxygen;
• chemical hydrides.

This standard does not preclude the use of similar fuels or oxidants from sources other than
air provided the unique hazards are addressed through additional requirements.
