AMENDMENT 1
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 document may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.

INTRODUCTION to Amendment 1
This amendment to IEC 62282-3-201:2017 provides a method of estimating the electric and
heat recovery efficiency of small stationary fuel cell power systems for a duration of up to ten
years of operation. Furthermore, this amendment to IEC 62282-3-201:2017 provides an
evaluation method for electric demand-following small stationary fuel cell power systems, which
are operating at changing levels of power output. It has been developed as a reference for the
life cycle assessment calculations in IEC TS 62282-9-101.
3 Terms and definitions
Add, at the end of Clause 3, the following new entries:
3.41
test duration
duration of the complete test for the estimation of the electric and heat recovery efficiency up
to ten years of operation, comprising a specific number of test runs
3.42
degradation rate
reduction of the electric efficiency of a stationary fuel cell power system per time of operation
Note 1 to entry: The degradation rate is expressed in efficiency per cent points per time (%/h).
4 Symbols
Table 1 – Symbols and their meanings for electric/thermal performance
Replace the existing title of Table 1 with the following new title:
Symbols and their meanings for electric and thermal performance
Under the header relating to "Time", in the unit column for "Test duration", add the unit "h" after
"s" and insert between the existing definitions of "Test duration" and "Start-up time" the
following new symbol, definition and unit, as shown:

9 Test set-up
Add, after the first paragraph and before Figure 3, the following new paragraph:
For the electric demand-following test (14.14), the electric load shall be capable of applying or
simulating an electric load profile to the system. It may be replaced or upgraded by a device,
which is capable of doing this. Alternatively, the tested small stationary fuel cell power system
may be equipped with means for setting and operating a load profile.
14 Type tests on electric/thermal performance
Replace the existing title of Clause 14 with the following new title:
Type tests on electric and thermal performance
Add, at the end of 14.12.11, the following new subclauses:
14.13 Estimation of electric and heat recovery efficiency up to ten years of operation
14.13.1 General
The main objective of this test is to identify and evaluate the environmental performance of a
small stationary fuel cell power system based on life cycle approach. The test estimates the
electric efficiency through lifetime due to long term effects on the small stationary fuel cell power
system.
NOTE Approximating the degradation rate on small stationary fuel cell power systems is only useful if there is
substantial daily operation, which is not the case for e.g. backup power systems.
Figure 16 shows an example of electric efficiency during ten years of operation.
