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 document applies to AC and DC type portable fuel cell power systems, with a rated output voltage not exceeding 600 V AC, or 850 V DC for indoor and outdoor use. These portable fuel cell power systems cannot be used in hazardous locations as defined in IEC 60050-426:2008, 426-03-01 unless there are additional protective measures in accordance with IEC 60079-0[5]¹⁾.

This document does not apply to portable fuel cell power systems that are

1) permanently connected (hard wired) to the electrical distribution system,

2) permanently connected to a utility fuel distribution system,

3) exporting power to the grid,

4) for propulsion of road vehicles,

5) 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 document

The following fuels and fuel feedstocks are considered within the scope of this document:

• natural gas,

• liquefied petroleum gas, such as propane and butane,

• liquid alcohols, for example methanol, ethanol,

• gasoline,

• diesel,

• kerosene,

• hydrogen,

• chemical hydrides.

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