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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
shall not be held responsible for identifying any or all such patent rights.

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 document describes type tests and their test methods only. In this document, no routine
tests are required or identified, and no performance targets are set.
A related but independent standard IEC 62282-3-201 on the performance test methods of small
stationary fuel cell power systems has been aligned with this document.
IEC 62282-3-200:2025 © IEC 2025
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, under specified
operating and transient conditions.
This document applies to all kinds of stationary fuel cell technologies, such as:
– alkaline fuel cells (AFC);
– phosphoric acid fuel cells (PAFC);
– polymer electrolyte fuel cells (PEFC);
– molten carbonate fuel cells (MCFC);
– solid oxide fuel cells (SOFC).
This document does not provide coverage for electromagnetic compatibility (EMC).
This document does not apply to small stationary fuel cell power systems with rated electric
power output of less than 10 kW which are dealt with in IEC 62282-3-201.
Fuel cell power systems can 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) is based on the conditions of the fuel at the boundary of the fuel cell power
system.
The document does not provide safety requirements for the testing of stationary fuel cell power
systems. Details on safe operation of the tested system can be obtained from the manufacturers
instructions.
