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 62282-6-106 has been prepared by IEC technical committee 105:
Fuel cell technologies
The Second Edition of IEC 62282-6-100 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 62282-6-100, and
the specific requirements for the individual fuel types within the other parts of the
IEC 62282-6 series.

The text of this International 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 106 provides additional requirements, specific to corrosive fuel formulations, which apply
3 in addition to the general requirements prescribed by IEC 62282-6-101. Part 106 is intended
4 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
7 intended to provide additional information and refined requirements, as appropriate.

16 1 Scope
17 1.1 Fuels and technologies covered by this part
18 Part 106 covers micro fuel cell power systems, micro fuel cell power units and fuel cartridges
19 using hydrogen produced from Class 8 (corrosive) borohydride formulations 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 corrosive fuel
22 formulation.
23 Figure 1 from IEC 62282-6-101 continues to apply.
24 2 Normative references
25 The normative references included in Clause 2 of IEC 62282-6-101 apply in their entirety to
26 technologies included in Part 106.
27 3 Terms and definitions
28 The terms and definitions below modify and augment those corresponding terms and
29 definitions in Clause 3 of Part 101 for micro fuel cell power systems and fuel cartridges
30 covered by this Part 106. All terms and definitions in Clause 3 not specifically mentioned here
31 also apply.
32 3.1
33 fuel
34 corrosive (UN Class 8) formulation of borohydride compounds used as fuel for an indirect
35 PEM micro fuel cell power system.
36 The formulation may contain a non-hazardous activator to facilitate the production of
37 hydrogen, and/or an inhibitor, such as an alkali metal hydroxide, to modulate or inhibit the
38 production of hydrogen from the corrosive fuel formulation. The formulation may be solid or
39 liquid, or may include both solid and liquid components that are combined during fuel
40 processing.
41 This Part 106 only applies to corrosive (UN Class 8) compounds which can be processed to
42 evolve hydrogen gas (e.g. though contact with water, non-hazardous or corrosive aqueous
43 solutions, and/or an activator).
44 Note 1 to entry: Guidance on classification of materials, including mixtures, may be found in the United Nations
45 Recommendations on the Transport of Dangerous Goods, Model Regulations current Edition.
46 The additional terms and their definitions below are needed for micro fuel cell power systems,
47 micro fuel cell power units and fuel cartridges covered by this Part 106 in addition to those
48 given in Clause 3 of IEC 62282-6-101.
49 The following additional terms and conditions shall also apply for the purposes of this
50 Part 106.
