This part of IEC 62282 covers construction, marking and test requirements for a.c. and d.c.
type portable fuel cell systems. These fuel cell systems are movable and not fastened or
otherwise secured to a specific location. The purpose of the portable fuel cell system is to
produce useable power.
This standard applies to a.c. and d.c. type portable fuel cell systems, with a rated output
voltage not exceeding 600 V a.c., or 850 V d.c. for indoor and outdoor use in a non-hazardous
area.
This standard does not apply to portable fuel cell 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 or auxiliary power of road vehicles;
e) micro fuel cell systems.
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.
