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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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 62282-3-1 has been prepared by IEC technical committee 105:
Fuel cell technologies.
The text of this standard is based on the following documents:
FDIS Report on voting
105/138/FDIS 105/143/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.

The committee has decided that the contents of this publication will remain unchanged until
the maintenance result 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

Safety



1 Scope
This part of IEC 62282 is a product safety standard suitable for conformity assessment as
stated in IEC Guide 104:1997, ISO/IEC Guide 51:1999 and ISO/IEC Guide 7:1994.
This standard 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;
– systems intended to provide a.c. or d.c. power;
– systems with or without the ability to recover useful heat;
– systems 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
– portable fuel cell power systems;
– propulsion fuel cell power systems.
A typical stationary fuel cell power system is shown in Figure 1.

Figure 1 – Stationary fuel cell power systems

The overall design of the power system anticipated by this standard shall form an assembly of
integrated systems, as necessary, intended to perform designated functions, as follows.
– Fuel processing system: Catalytic or chemical processing equipment plus associated heat
exchangers and controls required to prepare the fuel for utilization within a fuel cell.
– Oxidant processing system: The system that meters, conditions, processes and may
pressurize the incoming supply for use within the fuel cell power system.
– Thermal management system: Provides cooling and heat rejection to maintain thermal
equilibrium within the fuel cell power system, and may provide for the recovery of excess
heat and assist in heating the power train during startup.
– Water treatment system: Provides the treatment and purification of recovered or added
water for use within the fuel cell power systems.
– Power conditioning system: Equipment which is used to adapt the electrical energy
produced to the requirements as specified
...
