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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
shall not be held responsible for identifying any or all such patent rights.
IEC 62282-6-106 has been prepared by IEC technical committee 105: Fuel cell technologies. It
is an International Standard.
This first edition, together with the other parts of the IEC 62282-6-1XX series, cancels and
replaces IEC 62282-6-100:2010 and IEC 62282-6-100:2010/AMD1:2012.
This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to
IEC 62282-6-100:2010 and IEC 62282-6-100:2010/AMD1:2012:
a) A new structure has been set up: IEC 62282-6-101 covers the general safety requirements
common to all fuel types whereas IEC 62282-6-102 and subsequent parts of the IEC 62282-
6-1XX series cover particular requirements for individual fuel types.

The text of this International Standard is based on the following documents:
Draft Report on voting
105/1017/FDIS 105/1025/RVD
Full information on the voting for its approval can be found in the report on voting indicated in
the above table.
The language used for the development of this International Standard is English.
This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in
accordance with ISO/IEC Directives, Part 1 and ISO/IEC Directives, IEC Supplement, available
at www.iec.ch/members_experts/refdocs. The main document types developed by IEC are
described in greater detail at www.iec.ch/publications.
A list of all parts in the IEC 62282 series, published under the general title Fuel cell
technologies, can be found on the IEC website.
This document is to be used in conjunction with IEC 62282-6-101:2024 and is not to be used
as a stand-alone document. This document provides additional requirements specific to
corrosive fuel formulations, which apply in addition to the general requirements specified in
IEC 62282-6-101:2024. The (sub)clause numbers in this document are aligned with those of
IEC 62282-6-101:2024 and are intended to provide additional information and refined
requirements, as appropriate.
The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under webstore.iec.ch in the data related to the
specific document. At this date, the document will be
• reconfirmed,
• withdrawn, or
• revised.
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.

Part 6-106: Micro fuel cell power systems – Safety –
Indirect Class 8 (corrosive) compounds

1 Scope
This part of IEC 62282 covers micro fuel cell power systems, micro fuel cell power units and
fuel cartridges using hydrogen produced from UN Class 8 (corrosive) borohydride formulations
as fuel. These systems and units use proton exchange membrane (PEM) fuel cell technologies.
The designs include fuel processing subsystems to derive hydrogen gas from the corrosive fuel
formulation.
