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 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.
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 62282-6-107 has been prepared by IEC technical committee 105:
Fuel cell technologies
The Second Edition of IEC 62282-6-101 and the other new parts of the IEC 62282-6 series
cancel and replace IEC 62282-6-100 published in 2010. This constitutes a technical revision.
The main changes with respect to the previous edition are as follows:
a) IEC 62282-6 series has been restructured and split in such a way as to have general
requirements for the safety of micro fuel cell power systems within IEC 62282-6-101, and
the specific requirements for the individual fuel types within the other parts of the
IEC 62282-6-1XX series.

The text of this standard is based on the following documents:
FDIS Report on voting
105/XX/FDIS 105/XX/RVD
Full information on the voting for the approval of this International Standard can be found in the
report on voting indicated in the above table.
This document 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 document will remain unchanged until the
stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to
the specific document. At this date, the document 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.

2 Part 107 provides additional requirements, specific to water-reactive fuel formulations, which
3 apply in addition to the general requirements prescribed by IEC 62282-6-101. Part 107 is
4 intended to be used together with IEC 62282-6-101, and shall not be utilized as a stand-alone
5 standard.
6 Clause and subclause numbers in this part are aligned with IEC 62282-6-101, and are intended
7 to provide additional information and refined requirements, as appropriate.

16 Scope
17 1.1 Fuels and technologies covered by this part
18 Part 107 covers micro fuel cell power systems, micro fuel cell power units and fuel cartridges
19 using hydrogen produced from water-reactive (UN Division 4.3) compounds as fuel. These
20 systems and units use proton exchange membrane fuel cell technologies. The designs may
21 include fuel processing subsystems to derive hydrogen gas from the water-reactive fuel
22 formulation.
23 This Part 107 only applies to water reactive (UN Division 4.3) solid compounds which solely
24 evolve hydrogen gas upon contact with water (or non-hazardous aqueous solutions). This Part
25 107 does not include compounds with a subsidiary hazard risk, or which are not permitted to
26 be transported by air according to the ICAO Technical Instructions.
