FUEL CELL TECHNOLOGIES –

Part 6-101: Micro fuel cell power systems –
Safety – General requirements


FOREWORD
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.
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.
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.
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.
IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment
services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by
independent certification bodies.
All users should ensure that they have the latest edition of this publication.
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.
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.
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 62282-6-100 Ed. 1 was prepared by IEC technical committee 105: Fuel cell technologies.
According to 105/266/DC the Standard IEC 62282-6-100 will be restructured to make it more user friendly.
The new standard series will consist of Part 6-101 and further Parts 6-1xxx.
Part 6-101 and subsequent Parts 6-1xxx will the replace IEC 62282-6-100, on a case by case basis, as fuel specific Part
2 standards are completed, a suitable transition period will be needed.

Part 101 will deal with general safety requirements common for all fuel technologies
Part 6-102 until 6-1xxx will deal with specific fuel technologies based on Part 6-101.

This constitutes a technical revision.

The main changes with respect to the previous edition are as follows:
a) IEC 62282-6-100 has been reformatted into two parts. Part 1 covers general requirements. Separate Part 2 documents cover
detailed requirements for specific fuel cartridges, as follows:

IEC Technology Supplement Standard Title
62282-6-102 Fuel cell technologies – Part 6-102:
Micro fuel cell power systems – Safety – Formic acid

62282-6-106 Fuel cell technologies – Part 6-106:
Micro fuel cell power systems – Safety – Indirect Class 8 (Corrosive)
Compounds

62282-6-107 Fuel cell technologies – Part 6-107:
Micro fuel cell power systems – Safety – Indirect water reactive (UN
Division 4.3) compounds


This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
A list of all parts of the IEC 62282 series, under the general title Fuel cell technologies, can be found on the IEC website.
The committee has decided that the contents of this publication will remain unchanged until the stability 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,
• withdrawn,
• replaced by a revised edition, or
• amended.

NOTE: The attention of National Committees is drawn to the fact that equipment manufacturers and testing organizations may
need a transitional period following publication of a new, amended or revised IEC publication in which to make products in
accordance with the new requirements and to equip themselves for conducting new or revised tests.
It is the recommendation of the committee that the content of this publication be adopted for implementation nationally not
earlier than 12 months from the date of publication.
A bilingual version of this publication may be issued at a later date.
