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.

The overall design of a portable fuel cell power system anticipated by this document forms 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
exchangers 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
provide for the recovery and utilization of excess heat and to assist in heating the fuel cell power
systems 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.
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 manufacturer’s 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 – either integral to the portable fuel cell power system or supplied through
a removable and refillable container assembly.
