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 second edition cancels and replaces the first edition of IEC 62282-3-200, published in
2011. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) a stabilization zone of ± 10 % for thermal output of 100 % response time is provided
instead of the tests for thermal output of 90 % response time, while the tests for electric
output of 90 % response time remain as an option;
b) the calculations for the ramp rate in kW/s are deleted and only the calculations for the
response time (s) remain;
– 6 – IEC 62282-3-200:2015 © IEC 2015
c) the procedures, criteria and figures of 9.3, Electric power and thermal power response
characteristics test, are modified to ensure they produce accurate and consistent results;
d) maximum acceptable instantaneous electric power output transient is moved to informative
Annex D.
IEC has published a related but independent standard IEC 62282-3-201 on performance test
methods of small stationary fuel cell power systems which is harmonized with this standard.
The text of this standard is based on the following documents:
FDIS Report on voting
105/547/FDIS 105/555/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 website 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.
This standard describes type tests and their test methods only. In this standard, no routine
tests are required or identified, and no performance targets are set.
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;
– electrical and heat recovery efficiency under specified operating conditions;
– environmental characteristics; for example, exhaust 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 are dealt with 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 system boundary of the fuel
cell power system:
– all energy recovery systems are included within the system boundary;
– all kinds of electric energy storage devices are considered outside the system 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.

background vibration level
mechanical oscillations caused by the environment that affect vibration level readings
Note 1 to entry: In this standard, background vibration is measured with the fuel cell power system in the cold
state.
3.1.4
cold state
state of a fuel cell power system at ambient temperature with no power input or output
3.1.5
discharge water
water discharged from the fuel cell power system including waste water and condensate
3.1.6
electrical efficiency
ratio of the average net electric power output produced by a fuel cell power system to the
average total power input supplied to the fuel cell power system
Note 1 to entry: Lower heating value (LHV) is assumed unless otherwise stated.
Note 2 to entry: Any electric power that is supplied to auxiliary machines and equipment of a fuel cell power
system from an external source is deducted from the electric power output of the fuel cell power system.

output”; “average total power input” instead of “total enthalpy flow”; Note 2 to entry” added]
3.1.7
external thermal energy
additional thermal energy input from outside the system boundary, such as cycle make-up and
process condensate return
3.1.8
fuel cell module
assembly incorporating one or more fuel cell stacks and, if applicable, additional components,
which is intended to be integrated into a power system
Note 1 to entry: A fuel cell module is comprised of the following main components: one or more fuel cell stack(s),
piping system for conveying fuels, oxidants and exhausts, electric connections for the power delivered by the
stack(s) and means for monitoring and/or control. Additionally, a fuel cell module may comprise: means for
conveying additional fluids (e.g. cooling media, inert gas), means for detecting normal and/or abnormal operating
conditions, enclosures or pressure vessels and module ventilation systems, and the required electronic
components for module operation and power conditioning.
