Part 2: Fuel cell modules


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 62282-2 has been prepared by IEC technical committee 105: Fuel
cell technologies.
This second edition cancels and replaces the first edition, published in 2004, its amendment 1
(2007) and constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
• inclusion of definitions for hazards and hazardous locations based on the IEC 60079
series;
• the general safety strategy is modified to reflect the needs for different application
standards. The modifications are in line with similar modifications made to
IEC 62282-3-100;
• the electrical components clause is modified to reflect the needs for different application
standards. The modifications are in line with similar modifications made to
IEC 62282-3-100;

• the marking and instructions have been enlarged to provide the system integrator with the
necessary information.
The text of this standard is based on the following documents:
FDIS Report on voting
105/378/FDIS 105/389/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.
A list of all the parts in the IEC 62282 series, published under the general title Fuel cell
technologies, can be found on the IEC website.
The reader's attention is drawn to the fact that Annex B lists all of the “in-some-country”
clauses on differing practices of a less permanent nature relating to the subject of this
standard.
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.

IMPORTANT – The 'colour inside' logo on the cover page of this publication indicates
that it contains colours which are considered to be useful for the correct
understanding of its contents. Users should therefore print this document using a
colour printer.

INTRODUCTION
Fuel cell modules are electrochemical devices which convert continuously supplied fuel, such
as hydrogen or hydrogen rich gases, alcohols, hydrocarbons and oxidants to d.c. power, heat,
water and other by-products.
Fuel cell modules are sub-assemblies that are integrated into end-use products incorporating
one or more fuel cell stacks and, if applicable, additional components.

FUEL CELL TECHNOLOGIES –

Part 2: Fuel cell modules



1 Scope
This part of IEC 62282 provides the minimum requirements for safety and performance of fuel
cell modules and applies to fuel cell modules with the following electrolyte chemistry:
– alkaline;
1
– polymer electrolyte (including direct methanol fuel cells) ;
– phosphoric acid;
– molten carbonate;
– solid oxide;
– aqueous solution of salts.
Fuel cell modules can be provided with or without an enclosure and can be operated at
significant pressurization levels or close to ambient pressure.
This standard deals with conditions that can yield hazards to persons and cause damage
outside the fuel cell modules. Protection against damage inside the fuel cell modules is not
addressed in this standard, provided it does not lead to hazards outside the module.
These requirements may be superseded by other standards for equipment containing fuel cell
modules as required for particular applications.
This standard does not cover road vehicle applications.
This standard is not intended to limit or inhibit technological advancement. An appliance
employing materials or having forms of construction differing from those detailed in the
requirements of this standard may be examined and tested according to the purpose of these
requirements and, if found to be substantially equivalent, may be considered to comply with
this standard.
The fuel cell modules are components of final products. These products require evaluation to
appropriate end-product safety requirements.
