SIST EN 62282-5-1:2008

Fuel cell technologies -- Part 5-1: Portable fuel cell power systems - Safety

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.

Brennstoffzellentechnologien -- Teil 5-1: Portable Brennstoffzellen-Energiesysteme - Sicherheit

Technologies des piles à combustible -- Partie 5-1: Systèmes à piles à combustible portables - Sécurité

Couvre les exigences de construction, de marquage et d'essai des systèmes à piles à combustible portables à courant alternatif et à courant continu. Ces systèmes à pile à combustible sont mobiles et ne sont ni attachés ni fixés par un autre moyen à un emplacement spécifique. Un système à pile à combustible est destiné à produire une puissance utile.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 62282-5-1 has been prepared by IEC technical committee 105:
Fuel cell technologies.
The text of this standard is based on the following documents:
FDIS Report on voting
105/135/FDIS 105/139/RVD

Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

The committee has decided that the contents of this publication will remain unchanged until
the maintenance result date indicated on the IEC web site under "http://webstore.iec.ch" in
the data related to the specific publication. At this date, the publication will be
• reconfirmed;

FUEL CELL TECHNOLOGIES –

Part 5-1: Portable fuel cell power systems –
Safety



1 Scope
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.
