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.

The overall design of the power system anticipated by this standard forms an assembly of
integrated systems, as necessary, intended to perform designated functions, as follows.
– Fuel processing system – System of chemical and/or physical processing equipment
plus associated heat exchanges and controls required to prepare, and if necessary,
pressurize, the fuel for utilization within a fuel cell power system.
– Oxidant processing system – System that meters, conditions, processes and may
pressurize the incoming supply for use within the fuel cell power system.
– Thermal management system – System that provides heating or cooling and heat
rejection to maintain the fuel cell power system in the operating temperature range, and
may provide for the recovery of excess heat and assist in heating the power train during
start-up.
– Water treatment system – System that provides all the necessary purification treatment
of the recovered or added water for use within the fuel cell power system.
– Power conditioning system – Equipment that is used to adapt the electrical energy
produced by the fuel cell stack(s) to application requirements as specified by the
manufacturer.

1 Scope
This part of IEC 62282 applies to stationary packaged, self-contained fuel cell power systems
or fuel cell power systems comprised of factory matched packages of integrated systems
which generate electricity through electrochemical reactions.
This standard applies to systems
– intended for electrical connection to mains direct, or with a transfer switch, or to a stand-
alone power distribution system;
– intended to provide AC or DC power;
– with or without the ability to recover useful heat;
– intended for operation on the following input fuels
a) natural gas and other methane rich gases derived from renewable (biomass) or fossil
fuel sources, for example, landfill gas, digester gas, coal mine gas;
b) fuels derived from oil refining, for example, diesel, gasoline, kerosene, liquefied
petroleum gases such as propane and butane;
c) alcohols, esters, ethers, aldehydes, ketones, Fischer-Tropsch liquids and other
suitable hydrogen-rich organic compounds derived from renewable (biomass) or fossil
fuel sources, for example, methanol, ethanol, di-methyl ether, biodiesel;
d) hydrogen, gaseous mixtures containing hydrogen gas, for example, synthesis gas,
town gas.
This standard does not cover:
– micro fuel cell power systems;
– portable fuel cell power systems;
– propulsion fuel cell power systems.
NOTE For special application such as “marine auxiliary power”, additional requirements may be given by the
relevant marine ship register standard.
This standard is applicable to stationary fuel cell power systems intended for indoor and
outdoor commercial, industrial and residential use in non-hazardous (unclassified) areas.
This standard contemplates all significant hazards, hazardous situations and events, with the
exception of those associated with environmental compatibility (installation conditions),
relevant to fuel cell power systems, when they are used as intended and under the conditions
foreseen by the manufacturer.
This standard deals with conditions that can yield hazards on the one hand to persons, and on
the other to damage outside the fuel cell system only. Protection against damage to the fuel
cell system internals is not addressed in this standard, provided it does not lead to hazards
outside the fuel cell system.
The requirements of this standard are not intended to constrain innovation. When considering
fuels, materials, designs or constructions not specifically dealt with in this standard, these
---------------------- Page: 11 ----------------------

FUEL CELL TECHNOLOGIES –
Part 3-100: Stationary fuel cell power systems –
Safety
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 62282-3-100 has been prepared by IEC technical committee 105:
Fuel cell technologies.
This bilingual version (2015-01) corresponds to the English version, published in 2012-02.
IEC 62282-3-100 cancels and replaces IEC 62282-3-1 published in 2007. IEC 62282-3-100
constitutes a technical revision.
IEC 62282-3-100 includes the following significant technical changes with respect to
IEC 62282-3-1:
a) general reorganization of the safety requirements;
b) major changes for addressing electrical safety requirements for internal components;
c) clarifications for numerous requirements and tests, particularly the pressure leakage and
strength tests;

d) expanded wind tests;
e) additional tests for condensate discharge and ventilation leakage.
The text of this standard is based on the following documents:
FDIS Report on voting
105/371/FDIS 105/384/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.
The French version of this standard has not been voted upon.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
A list of all the 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.

Figure 1 – Stationary fuel cell power systems
The overall design of the power system anticipated by this standard forms an assembly of
integrated systems, as necessary, intended to perform designated functions, as follows.
– Fuel processing system – System of chemical and/or physical processing equipment
plus associated heat exchanges and controls required to prepare, and if necessary,
pressurize, the fuel for utilization within a fuel cell power system.
– Oxidant processing system – System that meters, conditions, processes and may
pressurize the incoming supply for use within the fuel cell power system.
– Thermal management system – System that provides heating or cooling and heat
rejection to maintain the fuel cell power system in the operating temperature range, and
may provide for the recovery of excess heat and assist in heating the power train during
start-up.
– Water treatment system – System that provides all the necessary purification treatment
of the recovered or added water for use within the fuel cell power system.
– Power conditioning system – Equipment that is used to adapt the electrical energy
produced by the fuel cell stack(s) to application requirements as specified by the
manufacturer.
– Automatic control system – System(s) that is composed of sensors, actuators, valves,
switches and logic components that maintain the fuel cell power system parameters within
the manufacturer’s specified limits including moving to safe states without manual
intervention.
– Ventilation system – System that provides air through forced or natural means to the fuel
cell power system’s enclosure.
– Fuel cell modules – Equipment assembly of one or more fuel cell stacks which
electrochemically converts chemical energy to electric energy and thermal energy
intended to be integrated into a power generation system.
