The principal changes in EN 62282-3-200:2012 as compared with EN 62282-3-2:2006 aim to harmonize
with ASME PTC-50. They are as follows:
– the equations for efficiency calculation are changed from power-base to average powerbase, which is
obtained by dividing energy by test duration;
– the duration of the test and frequency of reading are changed;
– the efficiency test at partial load is no longer mandatory. Whether or not to conduct the test at partial
load should be determined by the parties conducting the tests;
– the flow rate measurement method is modified. Both mass flow rate and volume flow rate are used for
calculations of efficiency;
– the thermal energy input and mechanical energy input are incorporated into efficiency calculations.

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 62282-3-200 has been prepared by IEC technical committee 105:
Fuel cell technologies.
This first edition of IEC 62282-3-200 cancels and replaces the first edition of IEC 62282-3-2,
published in 2006, and constitutes a technical as well as a structural revision.
The principal changes in this first edition of IEC 62282-3-200 as compared with the first
edition of IEC 62282-3-2 aim to harmonize with ASME PTC-50. They are as follows:
– the equations for efficiency calculation are changed from power-base to average power-
base, which is obtained by dividing energy by test duration;
– the duration of the test and frequency of reading are changed;
– the efficiency test at partial load is no longer mandatory. Whether or not to conduct the
test at partial load should be determined by the parties conducting the tests;

– 6 – 62282-3-200  IEC:2011
– the flow rate measurement method is modified. Both mass flow rate and volume flow rate
are used for calculations of efficiency;
– the thermal energy input and mechanical energy input are incorporated into efficiency
calculations.
The development of an independent standard on performance test methods of small
stationary fuel cell power systems is currently under way (future IEC 62282-3-201). It will be
harmonized with this standard.
The text of this standard is based on the following documents:
FDIS Report on voting
105/340/FDIS 105/349/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.
A list of all the parts in the IEC 62282 series, published under the general title Fuel cell
technologies, can be found on the IEC website.
The committee has decided that the contents of this publication will remain unchanged until
the stability 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
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

INTRODUCTION
This part of IEC 62282 describes how to measure the performance of stationary fuel cell
power systems for residential, commercial, agricultural and industrial applications.
The following fuel cell types have been considered:
– alkaline fuel cells (AFC),
– phosphoric acid fuel cells (PAFC),
– polymer electrolyte fuel cells (PEFC),
– molten carbonate fuel cells (MCFC);
– solid oxide fuel cells (SOFC).

FUEL CELL TECHNOLOGIES –
Part 3-200: Stationary fuel cell power systems –
Performance test methods
1 Scope
This part of IEC 62282 covers operational and environmental aspects of the stationary fuel
cell power systems performance. The test methods apply as follows:
– power output under specified operating and transient conditions;
– electric and thermal efficiency under specified operating conditions;
– environmental characteristics; for example, gas emissions, noise, etc. under specified
operating and transient conditions.
This standard does not provide coverage for electromagnetic compatibility (EMC).
This standard does not apply to small stationary fuel cell power systems with electric power
output of less than 10 kW which will be dealt with in the future IEC 62282-3-201.
Fuel cell power systems may have different subsystems depending upon types of fuel cell and
applications, and they have different streams of material and energy into and out of them.
However, a common system diagram and boundary has been defined for evaluation of the
fuel cell power system (see Figure 1).
The following conditions are considered in order to determine the test boundary of the fuel
cell power system:
– all energy recovery systems are included within the test boundary;
– all kinds of electric energy storage devices are considered outside the test boundary;
– calculation of the heating value of the input fuel (such as natural gas, propane gas and
pure hydrogen gas, etc.) is based on the conditions of the fuel at the boundary of the fuel
cell power system.
