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 62282-3-201 has been prepared by IEC technical committee 105:
Fuel cell technologies.
This second edition cancels and replaces the first edition published in 2013. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) Revision of definitions
b) Revision of symbols (Clause 4, in accordance with ISO/IEC 80000 series and ISO/IEC
Directives Part 2);
c) Revision of Figures 2, 5 and 6;
d) Revision of test set-up (Clause 9);

e) Revision of measurement instruments (Clause 10);
f) Introduction of ramp-up test (14.6);
g) Introduction of rated operation cycle efficiency (14.11);
h) Introduction of electromagnetic compatibility (EMC) test (14.12);
i) Revision of exhaust gas test (15.3);
j) Introduction of typical durations of operation cycles (Annex F).
The text of this International Standard is based on the following documents:

the specific document. At this date, the document will be
• reconfirmed,
• withdrawn,

INTRODUCTION
This part of IEC 62282 provides consistent and repeatable test methods for the electrical,
thermal and environmental performance of small stationary fuel cell power systems.
This document limits its scope to small stationary fuel cell power systems (electrical power
output below 10 kW) and provides test methods specifically designed for them in detail. It is
based on IEC 62282-3-200, which generally describes performance test methods that are
common to all types of fuel cells.
This document is intended for manufacturers of small stationary fuel cell power systems
and/or those who evaluate the performance of their systems for certification purposes.
Users of this document may selectively execute test items that are suitable for their purposes
from those described in this document. This document is not intended to exclude any other
methods.

FUEL CELL TECHNOLOGIES –
Part 3-201: Stationary fuel cell power systems –
Performance test methods for small fuel cell power systems

1 Scope
This part of IEC 62282 provides test methods for the electrical, thermal and environmental
performance of small stationary fuel cell power systems that meet the following criteria:
• output: rated electric power output of less than 10 kW;
• output mode: grid-connected/independent operation or stand-alone operation with single-
phase AC output or 3-phase AC output not exceeding 1 000 V, or DC output not exceeding
1 500 V;
NOTE The limit of 1 000 V for alternating current comes from the definition for "low voltage" given in
IEC 60050-601:1985, 601-01-26.
• operating pressure: maximum allowable working pressure of less than 0,1 MPa (gauge) for
the fuel and oxidant passages;
• fuel: gaseous fuel (natural gas, liquefied petroleum gas, propane, butane, hydrogen, etc.)
or liquid fuel (kerosene, methanol, etc.);
• oxidant: air.
This document describes type tests and their test methods only. No routine tests are required
or identified, and no performance targets are set in this document.
This document covers fuel cell power systems whose primary purpose is the production of
electric power and whose secondary purpose may be the utilization of heat. Accordingly, fuel
cell power systems for which the use of heat is primary and the use of electric power is
secondary are outside the scope of this document.
All systems with integrated batteries are covered by this document. This includes systems
where batteries are recharged internally or recharged from an external source.
This document does not cover additional auxiliary heat generators that produce thermal
energy.
