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 62282-5-1 has been prepared by IEC technical committee 105:
Fuel cell technologies.

FUEL CELL TECHNOLOGIES –
Part 5-1: Portable fuel cell power systems –
Safety
1 Scope
This part of IEC 62282 covers construction, marking and test requirements for a.c. and d.c.
type portable fuel cell systems. These fuel cell systems are movable and not fastened or
otherwise secured to a specific location. The purpose of the portable fuel cell system is to
produce useable power.
This standard applies to a.c. and d.c. type portable fuel cell systems, with a rated output
voltage not exceeding 600 V a.c., or 850 V d.c. for indoor and outdoor use in a non-hazardous
area.
This standard does not apply to portable fuel cell systems that are:
a) permanently connected (hard wired) to the electrical distribution system;
b) permanently connected to a utility fuel distribution system;
c) exporting power to the grid;
d) for propulsion or auxiliary power of road vehicles;
e) micro fuel cell systems.
The following fuels and fuel feedstocks are considered within the scope of this standard:
• natural gas;
• liquefied petroleum gas, such as propane and butane;
• liquid alcohols, for example methanol, ethanol;
• gasoline;
• diesel;
• kerosene;
• hydrogen;
• metals (e.g. Mg, Al or Zn) or metal alloys immersed in electrolyte (e.g. aqueous solutions
of salts or alkali) in air or oxygen;
• chemical hydrides.
This standard does not preclude the use of similar fuels or oxidants from sources other than
air provided the unique hazards are addressed through additional requirements.

1.1 System boundary
The overall design of a portable fuel cell system anticipated by this standard shall form an
assembly of some or all of the following systems (see Figure 1), integrated as necessary, to
perform designated functions, as follows:
Fuel processing system – chemical processing equipment including any associated heat
exchanges and controls required to convert input fuel to a composition suitable for the fuel
cell stack.
Oxidant processing system – subsystem that meters, conditions processes, and may
pressurize the incoming oxidant supply for use within the fuel cell power system.
Thermal management system – subsystem intended to provide cooling and heat rejection in
order to maintain thermal equilibrium within the fuel cell power system, and, if necessary, to
affect the recovery of excess heat and to assist in heating the power train during start-up.
Power conditioning system- equipment which is used to change the magnitude or waveform
of the voltage, or otherwise alter or regulate the output of a power source.

62282-5-1 © IEC:2007 – 15 –
Automatic control system – assembly of sensors, actuators, valves, switches and logic
components (including process controllers) that maintains the fuel cell power system
parameters within the manufacturers specified limits without manual intervention.
Fuel cell module – assembly including a fuel cell stack(s) which electrochemically converts
chemical energy to electric energy and thermal energy intended to be integrated into a power
generation system.
Fuel supply system – shall be either integral to the portable fuel cell system, or supplied
through a removable and refillable container assembly.
Onboard energy storage system – an internal energy source intended to aid or complement
the fuel cell module in providing power to internal or external loads.
Ventilation systems – subsystem of the fuel cell power system that provides, by mechanical
means, air to its cabinet.
Water treatment systems – provides for treatment and purification of recovered or added
water for use within the portable fuel cell system.
1.2 Equivalent level of safety
These requirements are not intended to prevent the design and construction of a portable fuel
cell system not specifically prescribed in this standard, provided that such alternative has
been considered in testing and listing the portable fuel cell system. In considering alternative
designs or construction, the materials or methods used shall be evaluated as to their ability to
yield equivalent performance to that prescribed by this standard.
This standard does not cover requirements of pressurized or non-pressurized fuel supply
containers upstream of the appliance gaseous or liquid fuel supply connector that are not
integral to the portable fuel cell system.
1.3 General statements
All pressures in this standard are considered to be gauge pressures, unless otherwise
specified.

3.3
electromagnetic disturbance
EMD
any electromagnetic phenomenon which may degrade the performance of a device,
equipment or system, or adversely affect living or inert matter
[IEV 161-01-05]
3.4
enclosure
part of the equipment providing one or more of the functions as described in a), b) and c)
below
a) Fire enclosure – a part of the equipment intended to minimize the spread of fire or flames
from within.
b) Mechanical enclosure – a part of the equipment intended to reduce the risk of injury due to
mechanical and other physical hazards.
c) Electrical enclosure – a part of the equipment intended to limit access to parts that may be
at hazardous voltage or hazardous energy levels.
NOTE One type of enclosure can be inside another type (e.g. an electrical enclosure inside a fire enclosure or a
fire enclosure inside an electrical enclosure). Also, a single enclosure can provide the functions of more than one
type (e.g. those of both an electrical enclosure and a fire enclosure).
3.5
energy hazard
hazard considered to exist at any exposed live parts of a power supply if, between the
exposed live parts and an adjacent exposed live or unenergized metal part of different
polarity, there exists a potential of 2 V or more and either an available continuous power level
of 240 VA or more, or a reactive energy level of 20 J or more
3.6
hazardous location
any area or space where combustible dust, ignitable fibers, or flammables, volatile liquids,
gases, vapours or mixtures are or may be present in the air in quantities sufficient to produce
explosive or ignitable mixtures
3.7
hazardous energy level
stored energy level of 20 J or more, or an available continuous power level of 240 VA or
more, at a potential of 2 V or more
3.8
hazardous voltage
voltage exceeding 42,4 V a.c. peak (30 V r.m.s.), or 60 V d.c., existing in a circuit which does
not meet the requirements for a limited current circuit
3.9
heat deflection temperature
HDT
measure of a polymer’s resistance to distortion under a given load at elevated temperatures.
The deflection temperature is the temperature at which a test bar, loaded to the specified
bending stress, deflects by 0,25 mm
